Trying to foretell which rookie pitchers will contribute on the big-league stage (and be sleepers in fantasy baseball leagues) could be a idiot’s errand. It’s a digital certainty that sooner or later within the season nearly each big-league rotation will endure from accidents and lackluster efficiency, which is able to in flip result in alternatives for high prospects. In addition, some golf equipment will experiment with six-man rotations. Some will manipulate service time and name up their prospects at midseason, whereas others will wait till September to provide their minor leaguers an opportunity.
In different phrases, given the vary of potentialities, the one positive guess is that we’ll almost definitely be shocked by who will get referred to as up and when. So, within the spirit of controlling what we will management, the next is a listing of the top-20 rookie pitchers who’re more likely to make an early-season influence. This rating doesn’t essentially mirror long-term potential, however it’s how I might draft these guys in a re-draft fantasy league or organize them on watchlists for keeper and dynasty leagues.

2021 MLB Top Prospects: Fantasy Baseball Rookie Pitcher Sleepers
1. Sixto Sanchez, RHP, Miami. Sanchez impressed in 2020 throughout a late-season cameo and is projected to open the season within the Marlins’ rotation. He had a delayed begin to spring coaching however has loads of time to get into sport form. Sanchez has the potential to be a front-line starter given his high-90s fastball and plus change. He’ll must sharpen his breaking ball, be extra according to all his pitches, and learn to arrange hitters to succeed in his full potential, however in 2021 he ought to at the least match final 12 months’s efficiency (3.50 ERA, 1.20 WHIP, 9.0 Ok/9).
2. Ian Anderson, RHP, Atlanta. Anderson was dominant over six common season begins in 2020 after which excelled within the postseason. He’s in line for a rotation spot to open the season, and, whereas he in all probability gained’t match his 2020 numbers, he needs to be a stable contributor for the Braves. Anderson has a plus change that was nearly unhittable final season, a plus mid-90s fastball, and a stable breaking ball. He ought to publish an ERA below 4.00, a WHIP round 1.20, and a 9.0 Ok/9.
3. Triston McKenzie, RHP, Cleveland. Like Sanchez and Anderson, McKenzie additionally had a profitable big-league debut in 2020 and is projected to win a rotation spot this spring. McKenzie ranks decrease than the opposite two by way of each pure stuff and sturdiness. When wholesome, he has above-average command of 4 pitches: High-spin low-90s fastball, plus curve, improved slider, and stable change. However, he has had a tough time staying wholesome, and his slight body has raised questions on his long-term position. If he can final a full season, McKenzie can in all probability log numbers just like these of Anderson however with a barely higher WHIP and barely decrease strikeout totals.
4. Casey Mize, RHP, Detroit. Mize’s inventory took a success after he struggled in seven big-league begins final season, however he nonetheless has important potential. At his finest, Mize has glorious command of three plus pitches (nasty splitter, mid-90s fastball, and sharp slider), however his stuff was flat final season, with merely common motion and spin. He’s competing for a beginning position this spring, and even when he doesn’t break camp with the massive membership, he ought to achieve a rotation slot earlier than midseason. He’s somewhat little bit of a dangerous gamble for 2021 however I’m betting on the upside, which for Mize is that of a front-line starter.
5. Dane Dunning, RHP, Texas. Dunning was efficient in seven begins final season with the White Sox (3.97 ERA, 35 strikeouts, and .197 BAA in 34 innings) earlier than being traded to Texas within the offseason. He’s competing for a beginning spot this spring and will slot into the center of the Rangers rotation. Dunning has a above-average sinker/slider mixture and in addition mixes in a fringy four-seamer and common change. His command stuff ought to enable him to publish stable numbers (ERA of round 4.00, common WHIP, and near 9.0 Ok/9).
6. Deivi Garcia, RHP, New York Yankees. Garcia held his personal over six big-league begins final season and is competing for a rotation spot this spring. Garcia has a four-pitch combine, together with a plus curve, a vigorous low-90s fastball, a stable change and a growing slider. Garcia’s curve wasn’t that sharp throughout his six main league begins, however his fastball was an efficient weapon. He throws constant strikes however doesn’t all the time command his pitches throughout the zone, resulting in occasional bouts of gopher-itis. If he can regain the traditional chunk on his curve, he ought to higher final season’s numbers and publish an ERA within the 4.00s with a great WHIP and common strikeout totals.
7. Nate Pearson, RHP, Toronto. Pearson scuffled throughout a five-game big-league debut final season however was competing for a rotation spot this spring when a groin harm sidelined in early March. He now’s unlikely to open the season within the majors, however he if his harm doesn’t linger he needs to be again within the combine quickly. On pure stuff and potential, he’s one of many high pitchers on this listing. At his finest, Pearson instructions a wonderful high-90s fastball, a plus slider, and a stable change. He has the upside of a No. 2 starter, however he’ll must harness his stuff this in an effort to succeed within the bigs. If he can regain his command, he has the potential to publish massive strikeout totals and stable ratios.
8. Spencer Howard, RHP, Philadelphia. Howard struggled in six big-league begins final season however is within the combine for a rotation spot this spring. At his finest, Howard has elite stuff, together with a mid to high-90s fastball, a plus change, and a plus breaking ball. Howard didn’t command his pitches nicely final season, and his stuff didn’t have its traditional motion. If he can revert to his pre-2020 type, he profiles as a No. 2 starter. Even if he begins the season within the bullpen or at Triple-A, Howard ought to get one other look in Philadelphia’s rotation within the first half of 2021.
9. Luis Patino, RHP, Tampa Bay. Patino had a tough big-league debut as a reliever with the Padres final season earlier than being traded to the Rays within the offseason. In 2020, Patino’s usually stable command abandoned him as he walked 14 in simply 17 innings, however the Rays have a wonderful pitching growth program and may get him again on observe. At his finest, Patino has electrical stuff that includes an upper-90’s heater, a pointy slider, and a good changeup. He’s within the combine for a rotation spot this spring, and even when he opens within the bullpen or at Triple-A, he’s nearly sure to get an opportunity to begin for Tampa sooner or later in 2021. Long-term, he has the stuff to be a No. 2 starter.
10. Trevor Rogers, LHP, Miami. Rogers confirmed flashes of excellence (39 Ks in 28 IP) in a bumpy big-league debut final season and is competing for rotation spot this spring. Rogers has the stuff (mid-90s fastball, sharp slider, efficient change) to be a mid-rotation starter. If he can persistently execute all three pitches and refine his command, he might publish an ERA within the 4.00s and log greater than a strikeout per inning.
11. Emmanuel Clase, RHP, Cleveland. Clase missed all of 2020 because of harm and a PED suspension, however he’s a candidate to shut for Cleveland this season. I’m not sure he wins the job, however he might slot right into a setup position if he loses out. Clase’s predominant weapon is a triple-digit lower fastball that he pairs with a 90-mph slider. It’s a dominant arsenal when he’s finding, however it’s a hittable bundle if he’s not. Clase is a man to trace this spring. If he wins the nearer gig, he would transfer up 5 or so spots on this listing. If he’s a setup man, he would fall to the underside third.
12. Garrett Crochet, LHP, Chicago White Sox. Crochet impressed as a big-league reliever solely months after being drafted eleventh general. His triple-digit fastball was nearly unhittable regardless that he threw it 85 p.c of the time over six scoreless innings. His slider can be an above common weapon, and the event of his changeup offers him an opportunity to be a starter long-term. He’ll nearly definitely be a reliever for all of 2021, however his stuff is nice sufficient to dominate in a late-inning position.
13. Adbert Alzolay, RHP, Chicago Cubs. Alzolay carried out nicely in a late-season cameo (2.95 ERA, 29 Ks and simply 12 hits allowed in 21.1 IP) and is competing for a rotation spot this spring. Alzolay has a mid-rotation starter’s arsenal, however his command will decide whether or not he sticks as a starter. His mid-90s fastball, plus breaking ball, and stable change are efficient when he locates, however he’s a high-risk, high-reward man. If he improves his command, he’ll publish glorious strikeout numbers and stable ratios. If he can’t, he’ll have just a few good video games interspersed with some clunkers and will ultimately find yourself within the bullpen.
14. Michael Kopech, RHP, Chicago White Sox. Kopech missed the 2019 marketing campaign after present process Tommy John surgical procedure, then opted out of the 2020 marketing campaign. He is projected to open the season within the Sox bullpen, however he has the stuff to be a front-line starter. The staff has been clear that they anticipate Kopech to renew a beginning position however hasn’t dedicated to a timeline. In the meantime, Kopech’s electrical upper-90s fastball and plus slider ought to enable him to be an efficient late-inning reliever.
15. Kohei Arihara, RHP, Texas. Arihara involves the U.S. after a profitable profession in Japan, the place he was Nippon Professional Baseball’s finest pitchers. Arihara has a median fastball however reveals a deep repertoire that includes a stable splitter. He is projected to win a beginning spot this spring and may slot into the center of the Texas rotation. There’s not quite a lot of upside in his profile, however his glorious command and intensive pitch combine ought to enable him to stay within the rotation and publish common numbers.
16. A.J. Puk, LHP, Oakland. Puk is coming off shoulder surgical procedure and has been eased again into dwell motion this spring. When wholesome, there’s no denying the standard of his stuff – high-90s fastball and a plus slider that mission him as a No. 2 starter. However, shoulder surgical procedure is difficult to beat, and Puk has an extended harm historical past. Although Oakland is speaking about Puk as a rotation candidate, I simply don’t see it taking place in 2021. Instead, I believe the most effective case is that he pitches out of the bullpen, the place he assumes a late-inning position. If he’s wholesome, he ought to publish good numbers as a reliever. If he can enhance his command and present that he can throw a number of innings, he may even get some late-season begins.
17. Tarik Skubal, LHP, Detroit. Skubal was one of many quickest rising prospects heading into final season however had an underwhelming big-league debut in 2020 (5.63 ERA in 32 innings). He’s within the combine for a rotation spot this spring, however there’s a great probability he begins the 12 months within the minors. He’s a man to trace throughout Grapefruit League motion to see if he can regain his usually good command and if his offseason work to develop a split-change pays dividends. Skubal pitches off a mid-90s, high-spin fastball and initiatives as a stable mid-rotation starter. A sizzling spring might vault him up this listing.
18. Keegan Akin, LHP, Baltimore. Akin produced blended ends in restricted 2020 big-league motion and now enters this season with an opportunity to fit into the Baltimore rotation. Akin makes use of his low-90s fastball 60 p.c of the time, then mixes in a median change and two non-descript breaking pitches. The fastball-change combo is nice sufficient for him to outlive on the backend of a rotation, however that’s about it. His 2020 ratios (4.56 ERA, 1.44 WHIP) are in all probability what we’ll see him produce in 2021, and he ought to proceed to log strikeouts at a charge of at the least one per inning.
19. Dean Kremer, RHP, Baltimore. Kremer made 4 begins final season for Baltimore and is favored to win a rotation spot this spring. His fastball-curve combo are adequate for him to be a No. 4 or 5 starter, however his breaking ball doesn’t elicit many chase swings and the fastball doesn’t overpower hitters. He can in all probability enhance somewhat on final 12 months’s numbers (4.82 ERA, 1.45 WHIP), however don’t anticipate an excessive amount of greater than that.
20. Kyle Cody, RHP, Texas. Cody was efficient pitching principally out of the Rangers bullpen in 2020 and is competing for a rotation spot this spring. Cody has a median three-pitch combine (fastball, slider, change) and definitely has the stuff to be a back-of-the-rotation starter. His command might want to enhance to win and maintain a big-league spot.
