John Holobetz Is the Next Red Sox Pitching Prospect Worth Buying Into

John Holobetz could be the next dominant pitching prospect in a line of recent names that have stolen the show. We’ve seen Payton Tolle and Connelly Early already break through, and Anthony Eyanson is having a dream start to his professional career right now. Jake Bennett is in the majors as well. Holobetz is the next name Boston Red Sox fans need to buy stock in before it’s too late.

John Holobetz’s Updated Red Sox Scouting Report

Holobetz was originally a fifth-round pick in the 2024 MLB Draft when the Milwaukee Brewers selected him to be the next member of their pitching laboratory. Holobetz pitched for three seasons in college, with one run at Radford before logging a pair of years at Old Dominion to catch Milwaukee’s eye. He debuted with the then Single-A Carolina Mudcats before the Crew dealt him as part of a package deal in the Quinn Priester trade. 

Holobetz, voted as the Red Sox no. 15 prospect per Talk Sox, is currently with Boston’s Double-A affiliate, the Portland Sea Dogs. Through 14 appearances (13 of them starts), he has a 4-3 record with a 4.57 earned run average. Holobetz has 74 punchouts to 22 walks over 67.0 innings of work.

Building Off An Electric Fastball

Holobetz’s fastball has a 55-grade on MLB Pipeline’s 20-to-80 scouting scale. His primary offering is electric, but not in the way that most pitchers’ fastballs are. The pitch rides in between 92-95 miles per hour and can climb up to 97 on occasion, but his above-average extension and low release point gives the ball plenty of arm-side ride off of his hand. This makes his fastball extremely tough to time up, and he does a remarkable job of mitigating hard contact.

Opposing hitters managed just a .514 OPS against his fastball in 2025, making the 50-grade slider, 45-grade cutter and 45-grade changeup that much more impactful. The slider breaks both vertically and horizontally, and the changeup caused trouble for opposing hitters during his Old Dominion days. Everything starts with the fastball, though, and the better he tunnels it with the other pitches, the more effective he’ll be.

Controlling The Ballgame

Control is another prominent part of Holobetz’s game. The 23-year-old righty walked just 4 percent of hitters during the 2025 campaign, good enough for the second best rating in Minor League Baseball. The Pottsville, PA native has kept this reputation through his career thus far, logging 194 punchouts to only 42 walks for a better than 4-to-1 strikeout to walk ratio. This consistency earned him a 60-grade for control, as his ability to work through a lineup efficiently gives him back-end starter potential. 

A Realistic Timeline

When will this deceptive Red Sox prospect break into the big leagues? The Sox may be struggling in the win-loss column, but they are loaded with arms. Injuries aside, the rotation includes the likes of Garrett Crochet, Ranger Suarez, Sonny Gray, Payton Tolle, Connelly Early, Jake Bennett and then Anthony Eyanson, who is also in Double-A Portland, is lighting the world on fire. 

Just like how the trade market changed Holobetz’s trajectory by giving him a new organization, he may need it to come in handy again to cut out of what is a surplus of pitching talent in and around Boston. 

Overall, I’d guess he breaks in some time during the 2028 season, unless the ball club makes some splash moves and lets a few of the names above Holobetz go. His scouting report (per MLB Pipeline) describes him as a “high floor” player, so he should climb his way to the show. It’s just a matter of making room for him with so much talent standing in the way.
