Michael Kopech

Kopech threw one clean five-pitch inning last spring during Cactus League play, which marks his lone game action in over two years. He needed Tommy John surgery in September 2018 after a brief cup of coffee and opted out of the 2020 season due to the pandemic. He will be 30 months removed from TJS this spring. New pitching coach Ethan Katz said in December that Kopech is feeling great and the team expects him to compete for a rotation spot in camp. Kopech's arm should be healthy and fresh, but considering he has been unable to build up his workload, the White Sox will probably have to devise a creative way of managing him this season. Kopech has an 80-grade fastball, plus slider, improving changeup and shaky control. He is the type of pitching prospect who could dominate any team over six innings or get chased by any team before making it out of the third inning.

Since 2000, of six starting pitchers who had their first Tommy John surgery in September, as Kopech did in 2018, the average innings pitched in the season that began 18 months later was 101.2. Two of the six (Mike Hampton, Scott Mathieson) did not make it back at all during what should have been their comeback years. Kopech has an 80-grade fourseam fastball with elite spin and will flash a plus slider and plus changeup. However, his command and control are fringe-average at best. Considering command is often the last thing to return for pitchers coming off TJS, we should not panic if he is wild in spring training or even the first couple months of the season. He is undeniably a flyball pitcher, so home runs will sometimes follow his walks and hit batsmen. This is not the year to expect quality ratios, but there will be a lot of strikeouts if he is lucky enough to avoid setbacks when he starts to ramp up.

Chicago's tantalizing fireballer grinded his way to a late-season MLB debut, battling control issues at Triple-A for much of the season. The excitement was short lived, as he required Tommy John surgery in mid-September. Kopech gave up a run on 11 hits and one walk while hitting five batters and striking out nine over 11 innings in his first three MLB starts (two were cut short by rain). He was pummeled in his final start, which also included a rain delay before he tore his UCL. There is a lot of noise in his tiny MLB sample -- elbow issues resulted in his velocity ticking down in each successive start and only one was unaffected by rain -- but in his debut outing his 96.8 mph four-seamer averaged 2,629 rpm -- Justin Verlander led qualified starters at 2,618 rpm. He also flashed a plus slider and plus changeup. Kopech will miss all of 2019 and with a normal recovery he will be fully healthy for spring training in 2020 -- 17-plus months removed from the surgery.

Last year Kopech's doubters thought he would end up as a high-leverage reliever, but now he seems more likely to wind up on the cover of GQ than in a big-league bullpen. There are reasonable arguments for a couple other hurlers (Forrest Whitley and Alex Reyes), but Kopech will be ranked by most as the top pitching prospect in the game this offseason. In addition to his famed 80-grade fastball, which he can dial up to triple digits with ease, Kopech made massive strides with his slider and changeup. Both secondaries now project as plus offerings, and with improving command, a future No. 1 starter is coming into focus. The White Sox kept him at Double-A for most of 2017, but rewarded his improvement with a three-start run at Triple-A to close out the year. He will return to Charlotte, but he should spend the bulk of 2018 in the big-league rotation. His immediate floor is a high-strikeout ratio risk, but if he throws enough strikes, he could be an SP2 on a per-start basis.

Kopech made headlines in 2016, both bad and good. The bad was breaking his hand in spring training while getting into an altercation with a teammate, delaying his start to the season until July. Between this incident and missing 50 games of development in 2015 due to testing positive for a banned substance, there were some makeup questions dogging him. Once the 6-foot-3 right-hander started pitching, the good headlines started. His calling card is an overpowering fastball that touches triple digits. He breezed through Carolina League hitters, striking out 82 in 52 innings (14.2 K/9) and was clearly one of the top prospects in the Arizona Fall League. It is easy to see why the White Sox insisted Kopech be part of the deal for Chris Sale. Commanding the heater (5.0 BB/9 in 2016) in addition to improving the secondary offerings and building up innings (134.2 in three seasons) make up his to-do list for 2017.

Kopech is one of Boston’s better pitching prospects at the lower levels of the organization, projecting as a No. 2 starter if it all clicks for him. He was given a challenging assignment to Low-A Greenville to start the season and was successful at that level, finishing 4-5 with a 2.63 ERA while striking out 70 in 65 innings. The bad news is that Kopech was suspended 50 games for testing positive for Oxilofrine, a stimulant in violation of the Minor League Drug Prevention and Treatment Program. The suspension wiped out the rest of his regular season, leaving him only an option of working out at team’s training facility in Fort Myers. He was able to work on a few things there, in particular his off-speed stuff and ironing out his mechanics. Kopech participated in the Fall Instructional League, making up for some lost development time. His major areas of focus in 2016 are repeating his delivery, commanding his fastball and refining the secondary stuff. He’ll likely open at Greenville.

Kopech was the second of Boston's two first-round picks in the 2014 draft. Coming out of high school, he was immediately assigned to the Gulf Coast League, where he held opponents to a measly .216 average and .255 slugging percentage. His problems with control and command were evident -- nine walks in 13.2 innings -- but his mid-90s heater (touching 97-98 mph) was effective against other rookies. Kopech has a lot of moving parts to his delivery, but has already worked to correct some of that. His secondary pitches are works in progress, but his raw stuff gives him a high ceiling if it can be harnessed. The Red Sox may challenge him at Low-A Greenville in 2015 for his first full-season assignment.
