Up to date 2021 MLB Prime Prospects: Rating the rookies, sleepers to know in fantasy baseball dynasty/keeper leagues


The primary half of 2021 noticed a continued inflow of rookie expertise into the large leagues. The dual challenges of service time manipulation and final 12 months’s misplaced minor league season seemingly did little to impede the circulate of prospect expertise. As of the July 16 begin of the season’s second half, 19 of the preseason Prime 50 prospect rankings have both surpassed the edge for rookie eligibility (50 IP for pitchers, 130 at-bats for place gamers, or 45 complete days on an lively big-league roster not together with September) or are on an lively big-league roster — and fantasy baseball house owners in all kinds of leagues are taking discover.

The compressed minor league system, improved participant growth applications, and the monetary pressures that compel many golf equipment, particularly small-market groups, to “use or lose” their younger expertise are more likely to proceed to push golf equipment to aggressively promote high prospects.   

The second half of the season won’t see fairly the identical variety of high prospects making their big-league debuts, however there are not less than 10 guys on the present Prime 50 who ought to see main league motion earlier than 2021 is over. Most of the relaxation will compete for big-league roster spots in spring coaching subsequent 12 months.  

Two gamers who in all probability gained’t make it to the majors till late 2022 on the earliest are latest draftees Jack Leiter and Kumar Rocker. Whereas neither has formally signed, the possibilities of both not reaching a deal and returning to varsity is extraordinarily distant. There are different ’21 draftees with a lot of upside who may grace future Prime 50 lists, however Leiter and Rocker are the one two whose expertise deserves inclusion with out the advantage of any observe file in professional ball.

Bobby Witt, SS, Kansas Metropolis (No. 2). I’ve been gradual to get on the Bobby Witt bandwagon, however after seeing him in particular person on the Futures Sport in Denver, I’m now all in. Witt confirmed electrical bat velocity and elevated energy which ought to permit him to hit for plus energy. He wowed in batting apply and hit two rockets off plus velocity throughout the recreation itself. His swing path is extremely environment friendly and he ought to hit for common towards superior pitching as he positive aspects expertise.

Grayson Rodriguez, RHP, Baltimore (9). In all probability no pitching prospect has seen their inventory rise as a lot this season as Rodriguez. He had a wonderful 2019 marketing campaign at Low-A, however he has exploded this 12 months with a dominant efficiency in Excessive-A and Double-A. Rodriguez’s mid-90s fastball has gotten extra explosive, his command has improved, his three pitch combine is carving up good hitters and he’s wanting extra like a frontline man than the No. 2 or 3 starter that he gave the impression to be two years in the past.

Shane Baz, RHP, Tampa Bay (10). Baz has tightened up his supply and has begun to harness his energy stuff. He’s gone from a back-end starter to somebody who may very well be a No. 2. His mid-90s fastball regarded electrical once I noticed him on the Futures Sport. His slider was plus and his change was common to above common. With three authentic weapons, a lot improved command, and a rising observe file of success towards superior hitters, he’s on the cusp of the majors.

Francisco Alvarez, C, New York Mets (12). Alvarez had a breakout 2019 and continued to carry out in 2021. Alvarez has unbelievable bat velocity and great energy, however he can overswing and lose his bat path. When he’s at his finest he has good pitch recognition and makes use of a compact swing to make constant contact. He’s nonetheless a great distance from the majors, however he has severe upside and has the potential to hit for each common and energy.  

Nick Lodolo, LHP, Cincinnati (13). Lodolo has gone from a elegant school man with common stuff to somebody who now initiatives as a No. 2 starter. Lodolo has all the time has good command however his fastball now sits within the mid 90’s and had nice motion once I noticed him on the Futures Sport. His slider flashes plus and his change has change into an above-average weapon.  With three pitches and nice command, Lodolo may very well be pitching on the entrance of the Reds rotation earlier than too lengthy.

Riley Greene, OF Detroit (15). Greene was athletic however uncooked in his 2019 professional debut, however he’s added lots of polish since then though he’s nonetheless simply 20.  He’s nonetheless not totally tapping into his decrease half to generate energy, however his swing mechanics are higher, his bat velocity is plus, and he has wonderful hand-eye coordination.  He’ll have to proceed to work on his pitch recognition however he’s beginning to seem like the all-star the Tigers had been hoping for once they drafted him.   

Reid Detmers, LHP, Los Angeles Angels (16). Detmers has made fairly the impression in his first professional season (3.60 ERA and 90/17 Okay/BB in 50 innings whereas leap-frogging ranges and starting his professional profession in Double-A).  Detmers has a elegant four-pitch combine together with a low-to-mid-90s fastball. He instructions nicely and units up hitters. An improved slider to go along with his plus curve and stable change make him a possible No. 2 or 3 starter.

Hunter Greene, RHP, Cincinnati (26). Greene went from high prospect to Tommy John to afterthought all earlier than he turned 20.  Now, nonetheless shy of his twenty first birthday, Greene has begun to harness his triple-digit warmth and put up dominant numbers at Double-A. He hasn’t had the identical success at Triple-A, however he’s now beginning to seem like the front-line starter that everybody anticipated when he was drafted second general in 2017.


Nate Pearson, RHP, Toronto (31). Pearson had a breakout season in 2019 however accidents have slowed him since. When he’s wholesome, Pearson has good command of an overwhelming fastball that reaches triple digits, a plus slider, and a stable change. He ought to be not less than a No. 2 starter within the majors however repeated accidents have clouded his future.  

Matthew Liberatore, LHP, St. Louis (42). In 2019, Liberatore flashed a lot of upside as a future No. 3 starter. Two years later his stuff hasn’t improved, and he’s struggled towards superior hitters. He’s nonetheless simply 21, however he’ll have to sharpen his change or add weapons to succeed in his potential.   

Drew Waters, OF, Atlanta (44). Waters gained the Double-A Southern League batting title and MVP in 2019, however he’s struggled this season at Triple-A. After I noticed him in particular person throughout All-Star weekend he regarded like his steadiness was out of sync, he was getting too broad in his stance, and he was dropping the leverage in his swing. When he’s balanced and in sync, the switch-hitting Waters has above-average uncooked energy from each side of the plate. If he can regain the steadiness in his swing and enhance his pitch recognition, he nonetheless has lots of upside, however his struggles towards superior pitching increase questions on his future. 

Jordan Groshans, SS, Toronto (45). In 2019, Groshans regarded look a complicated hitter with plus energy potential and a stable general skillset. This season it doesn’t seem as if Groshans has developed a lot since then. He isn’t tapping into his energy in video games, and he’s wanting extra common than plus throughout the board. He nonetheless has time to develop but it surely seems to be like he’s stalled a bit.  

MacKenzie Gore, LHP, San Diego (46). On pure stuff, Gore may very well be a top-10 prospect. He was dominant in 2019, then misplaced management of his supply and hasn’t been in a position to get himself in sync since. Blisters have additionally been a persistent drawback. When he’s proper, he has 4 pitches, good command, and profiles as a front-line starter. If he can regain the consistency of his supply he’ll leap again up this record.  

Cristian Pache, OF, Atlanta (50). He was brutally overmatched in his big-league debut and hasn’t performed nicely at Triple-A. He’s nonetheless an elite middle fielder, which suggests he’ll get misplaced of possibilities to enhance his offense. Additionally, he’s simply 22 and has the bodily instruments to be an above-average hitter. In January I wrote that he’d want to enhance his plate self-discipline and refine his swing mechanics. Till he makes progress in these two areas, he’ll wrestle.
