10 Boston Red Sox Prospects To Know Beyond The Top 30 in 2024

31. Bryan Mata, RHP

Mata has yet to harness his standout raw stuff and owns a 12% career walk rate. His sinker sits at 97 mph and tops out at 99 while averaging 16 inches of arm-side run. Mata scaled back the usage of his secondaries as a reliever. He has the stuff to be a multi-inning impact contributor if he can throw enough strikes, but the clock is ticking. 

32. Marvin Alcantara, SS

Alcantara is one of the best defensive shortstops in the system, but his offense lagged as he wore down physically in his first season in the U.S. in 2023. If he can add strength to turn his bat-to-ball skills into serviceable offense, he has a chance to turn into a glove-first regular.

33. Brandon Walter, LHP

Walter, a 2019 26th-rounder, emerged as a top Red Sox pitching prospect in 2021-22, but was sidelined for much of 2022 due to a bulging disk. Though healthy in 2023, his stuff lacked its pre-injury bite. He avoided barrels in the big leagues in 2023. A return of both health and stuff could help him become a bulk reliever.

34. Luis Guerrero, RHP

Though he walks with a limp due to a complication from a surgery as an infant, Guerrero—a 2021 17^th rounder—hasn’t let the condition prevent him from developing on the mound. He throws hard, sitting at 97-98 mph and touching triple digits, but his fastball lacks deception, making it most effective in setting up his splitter and slider. He finished 2023 in Triple-A and could emerge as a big league bullpen depth option.  

35. Kristian Campbell, 2B/OF

The Sox tabbed Campbell in the fourth round of the 2023 draft based not only on his combination of bat-to-ball skills, strike-zone discipline, and plus speed but also a sense that he could add to his profile with strength gains and by getting exposure to the outfield, where his speed is an asset.  

36. Justin Riemer, SS/2B

Riemer showed exceptional contact skills at Wright State, where he posted 15 walks with just two strikeouts before blowing out his ACL after just 12 games of his redshirt sophomore year.  Though he is a shortstop now, Riemer profiles best as a second baseman. No matter where he plays, Boston believes in his hit tool.

37. Zach Penrod, LHP

The Sox signed Penrod out of the Pioneer League in 2023, giving him his first look in affiliated games in five years. The lefthander, who turns 27 in June, impressed by throwing strikes with a mid-90s fastball and a swing-and-miss changeup, then posted a 1.29 ERA in the AFL that was the lowest among starters with at least 10 innings. 

38. Corey Rosier, OF

Rosier has been traded twice since the Mariners took him in the 12^th round of the 2021 draft, with both the Padres and Red Sox drawn to his excellent speed (40-plus steals in both 2022 and 2023) and ability to get on base. Rosier’s high groundball rates limit his offensive ceiling. He’s played all three outfield spots and profiles best in left, but his speed alone gives him a reasonable shot at a big league role. 

39. Jedixson Paez, RHP

Paez pumps strikes with a fastball, curveball and changeup in a way that has allowed him to succeed against older opponents at the start of his pro career. He’s added some power to a fastball that sat in the mid 80s when he signed and that now lives in the 89-91 mph range and also shows a curveball with good shape. If he can continue to add strength to improve his stuff, he could emerge as a depth starter.   

40. Gilberto Bautista, RHP

Signed for $10,000 as a 17-year-old in November 2022, Bautista impressed by attacking hitters with a 93-95 mph fastball and slider in his pro debut in 2023, posting a 34% strikeout rate and 5% walk rate in the DSL. If he develops a third pitch, he could advance as a starter.
