Top Free Agents for 2018-2019: Pitchers

Starting Pitchers

1. Patrick Corbin (2019 Age: 29-30)
2018 Stats: 11-7, 3.15 ERA, 1.05 WHIP, 246/48 K/BB, 200 IP in 33 starts
There are no true aces available on the market this year, though 29 year old Patrick Corbin is arguably the closest. He has been improving steadily over the past three seasons, dropping his ERA from 5.15 in 2016 to 4.03 in 2017 and 3.15 in 2018 while increasing his strikeout rate from 18.7% to 21.6% to 30.8%. His big success in 2018 even came while losing velocity on his fastballs, which have dropped about 1.5 MPH over the past year. Still, you can't argue with the results this year, and the high strikeout rate paired with the low walk rate shows that very little luck was involved in his big season. As one of the younger arms available (he turns 30 in July), he has the ability to continue pitching at this #2 to #3 starter level for quite a few years, making him a candidate for a long term deal. For his career, the Syracuse native is 56-54 with a 3.91 ERA, a 1.28 WHIP, and an 897/271 strikeout to walk ratio over 172 games (154 starts) since 2012.

2. Dallas Keuchel (2019 Age: 31)
2018 Stats: 12-11, 3.74 ERA, 1.31 WHIP, 153/58 K/BB, 204.2 IP in 34 starts
Keuchel is a similar option to Corbin in terms of projection, though while Corbin is a strikeout pitcher, Keuchel gets his outs with ground balls. It's a more sustainable model for success later into into his career, but it's also more volatile due to the nature of batted balls (a strikeout is a strikeout regardless of luck, but bad luck with ground balls leads to more hits). He has to be weary that he was getting fewer swings and misses on all of his pitches, so continuing to keep the ball on the ground will be key for him. I think this season is indicative of how he will pitch going forward, as a solid #2 or #3 starter. For his career, the former Arkansas Razorback is 76-63 with a 3.66 ERA, a 1.25 WHIP, and a 945/343 strikeout to walk ratio over 192 games (183 starts) since 2012.

3. Charlie Morton (2019 Age: 35)
2018 Stats: 15-3, 3.13 ERA, 1.16 WHIP, 201/64 K/BB, 167 IP in 30 starts
Charlie Morton's career looked like it was on the downswing in 2015 and, if you weren't looking closely, 2016. After posting a 4.81 ERA in 2015, he literally just decided to throw harder over the offseason. He was injured for much of 2016 but kept with the new deal, and he has been lights out ever since. Between 2017 and 2018, he went 29-10 with a 3.36 ERA and a 1.18 WHIP, striking out 364 and walking 114 in 313.2 innings. All of this by just deciding to throw harder. He literally added about 2.5 MPH to his sinker and nearly 4 MPH to his fastball, and the result has been taking a back-end starter and making him into a solid #3 or even #2 starter. Turning 35 this offseason, he won't get a long term deal, but he'll be a very useful starting pitcher for any team over the next couple of seasons. For his career, the Connecticut native is 75-81 with a 4.23 ERA, a 1.37 WHIP, and a 994/451 strikeout to walk ratio over 217 games (216 starts) since 2008.

4. Nathan Eovaldi (2019 Age: 29)
2018 Stats: 6-7, 3.81 ERA, 1.13 WHIP, 101/20 K/BB, 111 IP in 22 games (21 starts)
It's hard to peg Eovaldi's value exactly because he has a lot of factors in his favor and a lot against him, and it all averages out to an average pitcher. He missed the 2017 season with Tommy John surgery and hasn't qualified for the ERA title (162+ IP) since 2014. However, he's been pretty consistent when on the mound, and he posted his second best ERA (3.81), best WHIP (1.13), and best K/BB (101/20) in 2018. Flipping back to the negative side, that 2014 season was his only full season. And on the positive, he turns 29 in February and is one of the youngest free agent starters available. Going forward, the hard throwing right hander has built his value up enough with a strong postseason to be a safe bet to be a valuable #3 or #4 starter, but only if he's healthy. The health isn't a safe bet, which knocks his value, but overall he'll be a good addition to any rotation that has the depth to make up for injuries should they strike. His excellent performance in the playoffs certainly helps. For his career, the Houston area native is 44-53 with a 4.16 ERA, a 1.35 WHIP, and a 640/259 strikeout to walk ratio in 156 games (148 starts) since 2011.

5. Hyun-Jin Ryu (2019 Age: 32)
2018 Stats: 7-3, 1.97 ERA, 1.01 WHIP, 89/15 K/BB, 82.1 IP in 15 starts
Ryu, like Eovaldi, is difficult to rank. He is clearly a #2 starter when healthy, but health has been a huge issue with trips to the disabled list stemming from his shoulder, elbow, both hips, foot, and groin all since 2014, which was also the last time he threw 150 innings in a season. This year, Ryu was dynamite when he was actually on the mound, posting a 1.97 ERA, a 1.01 WHIP, and an 89/15 strikeout to walk ratio over 82.1 innings. While he's not a guy that will sustain those numbers over a full season, he has proven he is perfectly capable of ERA's consistently below 3.50 when on the mound. While age might render him even more susceptible to injury, he's healthy right now, and that's saying a lot. For his career, the South Korean lefty is 40-28 with a 3.20 ERA, a 1.22 WHIP, and a 502/140 strikeout to walk ratio over 97 games (96 starts) since 2013.

6. J.A. Happ (2019 Age: 36)
2018 Stats: 17-6, 3.65 ERA, 1.13 WHIP, 193/51 K/BB, 177.2 IP in 31 starts
J.A. Happ may have just turned 36 during the playoffs, but he's still a valuable #3 starter even in his mid 30's. He has made at least 25 starts in each of the past five seasons and has kept his ERA below 3.70 in each of the past four, and deeper analytics show no sign of him slowing down. I think he's the safest bet on this list, at least in the short term, to give you exactly what you expect: 150-180 innings, a sub-4.00 ERA, good command, and relative start-to-start consistency. He only ranks this low because even just a three year deal will see him pitch right up to his 39th birthday. For his career, the former Northwestern Wildcat is 109-82 with a 3.90 ERA, a 1.31 WHIP, and a 1357/556 strikeout to walk ratio over 284 games (259 starts) since 2007.

7. Yusei Kikuchi (2019 Age: 27-28)
2018 Stats (NPB): 14-4, 3.08 ERA, 1.03 WHIP, 153/45 K/BB, 163.2 IP in 23 starts
Japan's Seibu Lions will be posting 27 year old lefty Yusei Kikuchi this year, and he could be a mid-rotation starter right off the bat. In 2017, Kikuchi had a huge year in Japan by going 16-6 with a 1.97 ERA, 0.91 WHIP, and a 217/49 strikeout to walk ratio in 187.2 innings. He took a minor step back in 2018 with a 3.08 ERA, a 1.03 WHIP, and a 153/45 strikeout to walk ratio in 163.2 innings, but he was still effective with a 23.4% strikeout rate and just a 6.9% walk rate. Kikuchi throws a mid 90's fastball, a good slider, and a curve and changeup, the classic mid-rotation arsenal, and he commands it all well. For his career (in Japan), Kikuchi is 73-46 with a 2.77 ERA, a 1.17 WHIP, and a 903/371 strikeout to walk ratio over 158 starts since 2011.

8. Lance Lynn (2019 Age: 32)
2018 Stats: 10-10, 4.77 ERA, 1.53 WHIP, 161/76 K/BB, 156.2 IP in 31 games (29 starts)
After years of being a well above average starter, Lynn's ERA jumped above 4.00 for the first time in his seven year career, landing way up there at 4.77. He was actually throwing a little bit harder and was keeping the ball on the ground better in 2018, but he stopped throwing strikes and his walk rate rose to a career-high 10.9%. Interestingly, even though Lynn's 3.43 ERA in 2017 was far better than his 4.77 ERA in 2018, deeper analytics such as FIP and xwOBA actually think he was a better pitcher in 2018 and the difference was simply luck. I somewhat agree, and while I think he's done with those ERA's around 3.00, I think he settles in around 4.00 for the next few seasons, considering he doesn't turn 32 until May. For his career, the former Ole Miss Rebel is 82-57 with a 3.57 ERA, a 1.32 WHIP, and a 1080/445 strikeout to walk ratio over 214 games (190 starts) since 2011.

9. Drew Pomeranz (2019 Age: 30)
2018 Stats: 2-6, 6.08 ERA, 1.77 WHIP, 66/44 K/BB, 74 IP in 26 games (11 starts)
It's tough to know exactly where to rank Pomeranz, who was an above average starting pitcher from 2016-2017 (38-18, 3.32 ERA, 1.27 WHIP, 360/134 K/BB) but who struggled in 2018 (2-6, 6.08 ERA, 1.77 WHIP, 66/44 K/BB). He has always been inconsistent, interspersing dominant stretches with times where it looked like he couldn't get anyone out. While he was at his best often in that 2016-2017 stretch, 2018 was a different ballgame as he lost about 1-2 MPH and forgot how to throw strikes. He turns 30 in a few weeks, so he's one of the younger free agents available, and a team that thinks they can unlock his 2016-2017 success will have a young, effective arm on their pitching staff. For his career, Lance Lynn's Ole Miss teammate is 44-48 with a 3.92 ERA, a 1.35 WHIP, and a 687/305 strikeout to walk ratio over 196 games (122 starts) since 2011.

10. Gio Gonzalez (2019 Age: 33)
2018 Stats: 10-11, 4.21 ERA, 1.44 WHIP, 148/80 K/BB, 171 IP in 32 starts
Honestly, it's hard to know what to expect from Gio Gonzalez. After watching him for six and a half years in Washington, I can tell you that you never know what kind of game Gio is going to have until about the fourth or fifth inning. He tends to cruise early on before either finishing off a gem or falling apart, and it has led to wildly erratic seasons: a 4.57 ERA in 2016, 2.96 in 2017, and 4.21 in 2018. You can look at him month to month, as he posted a 2.10 ERA over the first two months this year, a 6.53 ERA over the next three months, and a 2.13 ERA in the final month. He'll probably continue to be maddeningly inconsistent over the next couple of seasons, but with enough good days to fit into most rotations. On his side is the fact that his one consistent attribute has been health, making at least 27 starts in each of the past nine seasons and at least 31 starts in each of the past four. For his career, the Miami native is 127-97 with a 3.69 ERA, a 1.32 WHIP, and a 1748/759 strikeout to walk ratio over 313 games (307 starts) since 2008.

11. Garrett Richards (2019 Age: 30-31)
2018 Stats: 5-4, 3.66 ERA, 1.28 WHIP, 87/34 K/BB, 76.1 IP in 16 starts
Honestly, I have no idea where to rank a guy who might not even pitch in 2019, so I'll slap him at number ten. Richards is an immensely talented arm who should already have a $100 million plus contract by now if he could actually stay healthy, and while he is 6-9 with a 3.05 ERA and a 1.22 WHIP over his last 28 starts, those 28 starts have been the entirety of his last three seasons. He'll miss most if not all of 2019 as well after undergoing Tommy John surgery in July, so he'll likely get at least a two year deal with most of the money deferred. There is recent precedent for this, with the Rays signing Nathan Eovaldi to a two year deal before the 2017 season with full knowledge he would not pitch until 2018, and it worked out for them. Richards is a better arm, near ace-like when he is healthy, though his high numbers of unearned runs should be a minor red flag. He's so talented that I really hope he can get it together and have a productive, healthy 2020 season. For his career, the former Oklahoma Sooner is 45-38 with a 3.54 ERA, a 1.25 WHIP, and a 645/268 strikeout to walk ratio over 170 games (115 starts) since 2011.

12. Jeremy Hellickson (2019 Age: 32)
2018 Stats: 5-3, 3.45 ERA, 1.07 WHIP, 65/20 K/BB, 91.1 IP in 19 starts
If it weren't for a down 2017 (5.43 ERA, 96/47 K/BB), Jeremy Hellickson would be a higher profile free agent this winter. He was very good in 2016 (3.71 ERA, 154/45 K/BB), and he was pitching well in 2018 (3.45 ERA, 65/20 K/BB) before a wrist injury shut him down for the most part in August. Turning 32 at the start of the 2019 season, he's not old as far as free agents go and probably has a few productive seasons in him as a #4 starter. While he hasn't been the most consistent, he is very effective during many stretches. For his career, the Des Moines native is 74-72 with a 4.07 ERA, a 1.24 WHIP, and an 899/365 strikeout to walk ratio over 223 games (216 starts) since 2010.

13. Clay Buchholz (2019 Age: 34-35)
2018 Stats: 7-2, 2.01 ERA, 1.04 WHIP, 81/22 K/BB, 98.1 IP in 16 starts
Honestly, it's hard to say what happened for Clay Buchholz in 2018. Released by the Royals in May, he ended up going 7-2 with a 2.01 ERA and a 1.04 WHIP over 16 starts for the Diamondbacks, allowing two or fewer earned runs in 14 of those 16 starts. His velocity was actually down, dropping 2-3 MPH from where he sat in his healthy 2015-2016 seasons. He also outperformed his peripheral stats, though his 3.47 FIP and .300 xwOBA (vs 2.01 ERA and .269 wOBA) aren't bad by any means. He did succeed with a career-best 32.4% chase rate, but he's been pretty consistent with that metric throughout his career and his next best season was 32.3% in 2015 (3.26 ERA). Overall, it's hard to know what to expect from Buchholz going forward, but he has a very good chance of at least being a productive starter if he can maintain some of whatever gave him success in 2018. For his career, the southeast Texas native is 88-64 with a 3.86 ERA, a 1.29 WHIP, and a 985/442 strikeout to walk ratio in 224 games (206 starts) since 2007.

14. Matt Harvey (2019 Age: 30)
2018 Stats: 7-9, 4.94 ERA, 1.30 WHIP, 131/37 K/BB, 155 IP in 32 games (28 starts)
The Matt Harvey who posted three straight seasons with an ERA under 2.75 from 2012-2015 (sitting out 2014 with Tommy John) isn't coming back, but Harvey doesn't turn 30 until spring training and had a great strikeout to walk ratio (131/37) in 2018 while turning around his season, and maybe his career, with the Reds. After posting a 7.00 ERA and a 20/9 strikeout to walk ratio before the trade, his ERA dropped to 4.50 in 24 starts with the Reds as he struck out 111 and walked 28 in 128 innings. A team that thinks it can bring Harvey further along towards its former self will hope to get a #4 starter out of him. For his career, the former UNC Tar Heel is 41-44 with a 3.80 ERA, a 1.20 WHIP, and a 723/203 strikeout to walk ratio over 133 games (128 starts) since 2012.

15. Trevor Cahill (2019 Age: 31)
2018 Stats: 7-4, 3.76 ERA, 1.19 WHIP, 100/41 K/BB, 110 IP in 21 games (20 starts)
Cahill has been very inconsistent throughout his career, serving as a valuable mid-rotation starter from 2009-2013 before being ineffective from 2014-2015, having a good year as a reliever in 2016, putting up and up and down 2017, and finally having a solid 2018. This past year, he was 7-4 with a 3.76 ERA and a 1.19 WHIP, the latter of which was his best since his 1.11 WHIP in 2010, and his 9.1% walk rate was his lowest since 2015. Overall, he can't be counted on to contribute a full season's worth of innings to a starting rotation, either because of injuries or because of ineffectiveness, with his most recent qualifying season (162+ IP) coming in 2012. He's likely a good option to make 20 or so solid starts. For his career, the San Diego area native is 80-83 with a 4.08 ERA, a 1.36 WHIP, and a 1007/548 strikeout to walk ratio over 304 games (208 starts) since 2009.

Right Handed Relievers
Note: RE24 stands for Run Expectancy 24, a theoretical stat which measures the run expectancy subtracted from one at bat to the next. An RE24 of 5.00 would mean that a pitcher has taken five runs off his team's theoretical run expectancy based on the situations he inherited and left. Higher is better and it is both cumulative (like fWAR as opposed to ERA) and park adjusted. More here.

1. Craig Kimbrel (2019 Age: 30-31)
2018 Stats: 2.74 ERA, 0.99 WHIP, 16.93 RE24, 96/31 K/BB, 62.1 IP in 63 appearances
Kimbrel is the best reliever on the market, and he'll probably make something close to the $80 and $86 million given to Kenley Jansen and Aroldis Chapman, respectively, though I don't think he'll reach quite that high. While Kimbrel was easily the best reliever in baseball from 2012-2014, he has been more inconsistent since 2015. His ERA reached as high as 3.40 in 2016, when his WHIP was a career-high 1.09 and his strikeout and walk rates were among the worst of his career. Then in 2017, his ERA dropped to 1.43, his WHIP to 0.68, and his strikeout and walk rates to among the best of his career. This past year was something in the middle, with a 2.74 ERA, a 0.99 WHIP, and a 38.9% strikeout rate to a 12.6% walk rate. Whether he can maintain himself as one of the best in the game going forward depends on whether he can maintain his command, which is a valid question, but he should continue to remain elite or at least very, very good for the next few seasons. He's also younger, turning 31 in May. For his career, the Huntsville, Alabama native has a 1.91 ERA, a 0.92 WHIP, and an 868/205 strikeout to walk ratio over 542 appearances.

2. Adam Ottavino (2019 Age: 33)
2018 Stats: 2.43 ERA, 0.99 WHIP, 23.77 RE24, 112/36 K/BB, 77.2 IP in 75 appearances
Pitchers in Colorado often fly under the radar, and that is what Adam Ottavino has done. He doesn't have the name recognition of Craig Kimbrel, but he's a great option that will come slightly cheaper. Over 75 appearances this season, he had a 2.43 ERA, a 0.99 WHIP, and a 112/36 strikeout to walk ratio in 77.2 innings, finishing ninth in all of baseball (min. 50 IP) with his 36.3% strikeout rate, three spots behind Kimbrel and his 38.9% rate. While walks were a little bit of a problem, he was nearly un-hittable and should be a viable closing option wherever he goes. For his career, the righty out of Northeastern University has a 3.68 ERA, a 1.30 WHIP, and a 464/174 strikeout to walk ratio over 366 games (3 starts) since 2010.

3. Jeurys Familia (2019 Age: 29)
2018 Stats: 3.13 ERA, 1.22 WHIP, 9.76 RE24, 83/28 K/BB, 72 IP in 70 appearances
Familia has had so much happen in his career, from ups and downs as the Mets closer to a 2016 domestic violence charge that was ultimately dropped to his 2018 trade to Oakland, that is easy to forget he'll spend the whole 2019 season at 29 years old. Familia was one of the better relievers in baseball from 2014-2016 when his ERA's were 2.21, 1.85, and 2.55, respectively, though recently he has fallen into more of a second tier category. In 2018, he posted a 3.13 ERA and a 1.22 WHIP while striking out 83 and walking 28 over 72 innings, showing shut-down stuff on most nights but also being subject to the occasional rough game. He's younger than the above two options but less consistent, so he offers a cheaper option to those two, still with closing experience. For his career, the Dominican has a 2.73 ERA, a 1.21 WHIP, and a 369/143 strikeout to walk ratio over 343 games (one start) since 2012.

4. Kelvin Herrera (2019 Age: 29)
2018 Stats: 2.44 ERA, 1.20 WHIP, 8.72 RE24, 38/10 K/BB, 44.1 IP in 48 appearances
Herrera, like Familia, was one of the better relievers in baseball from 2014-2016 with ERA's of 1.41, 2.71, and 2.75, respectively, though also like Familia, he was down a bit in 2017 and has been inconsistent in 2018. This year, as of June 21st (two games after his trade from Kansas City to Washington), he had a 0.98 ERA, a 0.76 WHIP, and a 22/2 strikeout to walk ratio over 27.2 innings. From then on, though, he had a 4.86 ERA, a 1.92 WHIP, and a 16/8 strikeout to walk ratio in 16.2 innings. It's hard to know what to expect out of him going forward, but he's likely to be at least a solid late-inning guy, and when he's at his best he's still one of the best in the game. Also in his favor is that he'll spend all of 2019 at 29 years old, making him one of the younger free agents available. For his career, the Dominican has a 2.82 ERA, a 1.15 WHIP, and a 454/136 strikeout to walk ratio over 463 appearances since 2011.

5. David Robertson (2019 Age: 34)
2018 Stats: 3.23 ERA, 1.03 WHIP, 6.81 RE24, 91/26 K/BB, 69.2 IP in 69 appearances
Now about a decade into his run as one of the game's better relievers, Robertson has managed remarkable consistency while most relievers around him suffer through ups and downs. Since 2011, his ERA has never gone above 3.47 and his WHIP has reached above 1.17 just once. This past year, those numbers were 3.23 and 1.03, respectively, and even though he'll turn 34 at the start of next season, I see no reason he can't be a late-inning reliever for the next couple of seasons. As far as relievers go, he's a high floor, low ceiling option in terms of output; you know what you are going to get. For his career, the University of Alabama alumnus has a 2.88 ERA, a 1.14 WHIP, and an 874/260 strikeout to walk ratio over 654 appearances since 2008.

6. Joakim Soria (2019 Age: 34-35)
2018 Stats: 3.12 ERA, 1.14 WHIP, 7.23 RE24, 75/16 K/BB, 60.2 IP in 66 appearances
Soria finds himself in a very similar spot to Robertson. Both have been unusually consistent for relievers, with Soria's ERA never reaching above 4.05 in any of his ten major league seasons. Over the last few seasons, his walk rate has been dropping, and his component ratios (strikeouts to walks to batters faced) leave him in a very good position to continue to be successful in the short run. Like Robertson, he's a safe bet, but probably at a slightly lower level of production. For his career, the Mexico native has a 2.88 ERA, a 1.13 WHIP, and a 688/189 strikeout to walk ratio over 639 appearances since 2007.

7. Cody Allen (2019 Age: 30)
2018 Stats: 4.70 ERA, 1.36 WHIP, 3.30 RE24, 80/36 K/BB, 67 IP in 70 appearances
After five straight seasons with ERA's below 3.00, it wasn't a great season for Cody Allen. His ERA ballooned from 2.94 last year to 4.70 this year while his WHIP jumped from 1.16 to 1.36. While he wasn't actually quite as bad as the ERA might say, he still wasn't great and his walk rate jumped to a career high 11.4% while his strikeout rate dropped to a career-low 27.7%. His velocity has also been trending down, and he's just no as deceptive as he was in years' past, which is interesting because he's just turning 30 at the beginning of the offseason. He's young enough to bounce back, but the trends aren't in his favor and I'm not confident he can drop his ERA back below 3.00 consistently. For his career, the Orlando native has a 2.98 ERA, a 1.19 WHIP, and a 564/173 strikeout to walk ratio over 456 appearances since 2012.

Left Handed Relievers

1. Andrew Miller (2019 Age: 33-34)
2018 Stats: 4.24 ERA, 1.38 WHIP, 4.80 RE24, 45/16 K/BB, 34 IP in 37 appearances
After four years as the game's premier left handed reliever, Miller made three separate trips to the disabled list in 2018 while battling hamstring, knee, and shoulder problems. In between, his 4.24 ERA and 1.38 WHIP were his highest marks since 2011, when he was a starter for the Red Sox. His strikeout rate also dipped below 30% for the first time since that year. It seems that his troubles likely originated from those injuries, as it is really tough to get anything going when you're always playing hurt. To me, his production in 2019 will not be a matter of his performance, but his ability to stay healthy and on the mound. A healthy Miller likely drops his ERA back below 3.00, in my opinion, even though he turns 34 in May. For his career, the former UNC Tar Heel has a 3.98 ERA, a 1.34 WHIP, and an 853/335 strikeout to walk ratio over 483 games (66 starts) since 2006.

2. Zach Britton (2019 Age: 31)
2018 Stats: 3.10 ERA, 1.23 WHIP, 5.15 RE24, 34/21 K/BB, 40.2 IP in 41 appearances
It has been mostly downhill since Britton posted a 0.54 ERA and a 0.84 WHIP in 2016, finding himself on and off the disabled list. He still posted a 3.10 ERA over 41 appearances this year, though his 20.1% strikeout rate and career-high 12.4% walk rate leave something to be desired. He's still young, turning 31 in December, so his signing team should still hope to get a late-inning reliever out of him. For his career, the Weatherford, Texas native has a 3.21 ERA, a 1.26 WHIP, and a 446/205 strikeout to walk ratio over 331 games (46 starts) since 2011.

3. Justin Wilson (2019 Age: 31)
2018 Stats: 3.46 ERA, 1.43 WHIP, 4.82 RE24, 69/33 K/BB, 54.2 IP in 71 appearances
Wilson has been up and down throughout his career, but with a rising walk rate, he's looking closer to a lefty specialist than the closer he was for much of 2017. In 2018, lefties slashed just .188/.301/.342 with a 34.4% strikeout rate against him, while right handed hitters hit a healthier .244/.350/.358 with a 25.9% strikeout rate. He's not strictly a specialist at this point, but the Cubs clearly saw a little bit of that in him as he managed just 54.2 innings in his 71 appearances, well under an inning per appearance. For his career, the former Fresno State Bulldog has a 3.33 ERA, a 1.27 WHIP, and a 407/166 strikeout rate over 412 appearances since 2012.
