Red Sox acquire pitching prospect John Holobetz from Brewers to complete Quinn Priester trade

Exactly four weeks after dealing right-hander Quinn Priester to the Brewers, the Red Sox completed their April 7 trade with Milwaukee by adding some minor-league pitching depth on Monday.

Having already obtained outfielder Yophery Rodriguez and a competitive balance draft pick (33rd overall in this year’s draft) last month, Boston acquired minor-league righty John Holobetz from Milwaukee as the player to be named later (as opposed to cash considerations) in the deal to officially complete the swap.

Holobetz, 22, was selected by the Brewers in the fifth round (156th overall) of last summer’s draft out of Old Dominion (where he primarily pitched out of the bullpen) by way of Radford. The Pennsylvania native signed with Milwaukee for an under-slot $322,500 but did not make his professional debut until this April. He posted a 3.00 ERA (2.48 FIP) with 31 strikeouts to five walks in five outings (three starts) spanning 24 innings for Low-A Carolina to begin the 2025 season. Opposing hitters batted just .180 against him.

Among 15 qualified Carolina League pitchers, Holobetz currently leads the pack in strikeout rate (31.3 percent), batting average against, WHIP (0.88), FIP, and xFIP (2.71). He also ranks second in strikeouts per nine innings (11.63), walks per nine innings (1.88), and walk rate (5.1 percent), and seventh in ERA, per FanGraphs.

Listed at 6-foot-3 and 190 pounds, Holobetz throws from a three-quarters arm slot and puts a lot of effort into his delivery. At present, he features a 92-94 mph fastball that has reached 96 mph this season, an 83-86 mph slider, and a high-80s changeup. According to Holobetz’s Baseball America pre-draft scouting report, “scouts believe the changeup is his best pitch, a potential weapon, but his breaking ball is more of a work in progress. Despite his reliever history, he throws enough strikes to potentially start in pro ball.”

Holobetz, who turns 23 in late July, has been assigned to Low-A Salem and will presumably report to Boston’s Carolina League affiliate in the coming days. Given how he has fared at the Low-A level thus far, though, it would not be all that surprising if Holobetz were to make his way to High-A Greenville before long.
