Scouting Report
Red Sox Video
Holobetz was the player to be named later in the Quinn Priester trade and immediately made an impact, beginning with High-A Greenville. Making 12 appearances there, Holobetz showcased an ability to keep walks limited as he allowed only 10 free passes in 63 innings of work. He also managed to strike out 62 batters in that same span. He would end up being promoted to Double-A Portland where he would finish the season, appearing in six games and tossing 37 2/3 innings to a 2.39 ERA. During that same span Holobetz looked even better, walking just five batters and allowing just one home run.
Holobetz starts on the first base side of the rubber and has a deceptive delivery, as he manages to hide the ball well. His repertoire is a fastball that can top out at 96 mph and has shown bat-missing ability and he’s comfortable using it at the top of the strike zone. He also has a slider that is his weakest pitch due to inconsistent feel. Entering spring training in 2026, he’s tweaked it to become more of a bullet slider.
The 23-year-old also has a curveball that he struggles to land in the strike zone consistently and a changeup that has some two-seamer action to it. Both pitches are viewed as being potentially average pitches with enough development.
Holobetz will begin 2026 back with Portland but should he do well to open the season and the Red Sox are forced to call up their starting pitching depth from Worcester, he could see a promotion to Triple-A by the middle of the season. Despite a decent fastball and an improved slider, Holobetz’s ceiling is likely that of a middle reliever unless he can develop a third reliable offering.
