Rockies right-hander Pierson Ohl, just acquired in a trade with the Twins last month, has been diagnosed with a torn ulnar collateral ligament in his right elbow and will undergo Tommy John surgery, reports Thomas Harding of MLB.com. Obviously, Ohl will miss the entire 2026 season. He can be transferred to the 60-day IL the next time Colorado needs a roster spot.
The 26-year-old Ohl made his big league debut with Minnesota in 2025, pitching 30 innings with a 5.10 earned run average — mostly out of the bullpen. He was outstanding in the minors, totaling 71 1/3 frames with a 2.40 ERA, a 30.3% strikeout rate and just a 3.9% walk rate. Ohl doesn’t throw hard, averaging only 91.9 mph on his four-seamer, but FanGraphs’ Eric Longenhagen credited him with a plus changeup (60 on the 20-80 scale) and potential plus-plus (70) command this past summer.
Though he’s not yet firmly established in the majors, Ohl had a clear opportunity to win a spot in Colorado’s bullpen. Victor Vodnik, Seth Halvorsen, Juan Mejia, Jimmy Herget, Brennan Bernardino and starter-turned-swingman Antonio Senzatela are highly likely to have spots, but Rule 5 pick RJ Petit is no lock to make the club and several of the other relievers still have minor league options remaining.
Those hopes are now dashed for the upcoming season. If there’s a silver lining for Ohl, it’s that moving to the 60-day IL will keep him in the majors all season, netting him a year of big league service and big league pay. The $780K major league minimum is nearly eight times the $100K bonus that Ohl received when signing as a 14th-round pick out of Grand Canyon University back in 2021.
Even if Ohl spends the entire 2026 season on the 60-day injured list and accrues a full year of service, he’ll still be a potential long-term option for Colorado. He came to the Rockies with just 62 days of MLB service, so he’d finish the season at 1.062 years and remain under club control — with a full slate of three minor league option years — for at least another five seasons. Ohl and former top infield prospect Edouard Julien (who’s out of minor league options) were traded from Minnesota to Colorado in exchange for pitching prospect Jace Kaminska late last month when the Twins needed some 40-man space.
