The Rockies have agreed to a minor league contract with left-handed reliever Parker Mushinski, per the transaction log at MLB.com. He’s represented by the Ballengee Group. It’s not listed on the transaction log, but Mushinski will be in camp next spring as a non-roster invitee, MLBTR has confirmed.
Mushinski, 30, has spent parts of three seasons in the majors — all of them as a member of the Astros. He’s pitched 33 big league frames and worked to a 5.45 ERA with a 17.4% strikeout rate, 8.1% walk rate and 45.2% ground-ball rate. Mushinski has done a nice job avoiding hard contact overall (average 88.4 mph exit velocity, 35.2% hard-hit rate), but much of the hard contact he’s allowed has been of the maximum-damage variety, especially against righties. He’s faced 83 right-handed opponents in the majors and served up five home runs.
Houston originally selected Mushinski out of Texas Tech in the seventh round of the 2017 draft. He spent his entire career in the Astros organization until this past season. Mushinski became a minor league free agent following the 2024 campaign and signed a minor league deal with the Guardians. The 6’0″, 225-pound southpaw spent last year in Triple-A Columbus, tossing 50 innings of 3.78 ERA ball. Mushinski fanned almost 30% of his opponents there but also walked nearly 15% of the batters he faced. In parts of five Triple-A seasons, Mushinski has a 3.71 ERA in 179 2/3 innings pitched.
Signing with the Rockies is a double-edged sword for any pitcher. On the one hand, the utter dearth of established big league arms on the staff creates plenty of opportunity, particularly for a non-roster player hoping to secure a bullpen spot. On the other hand, winning that roster spot means pitching home games at altitude and at the notoriously hitter-friendly Coors Field.
Mushinski becomes the second left-handed relief addition for Colorado in the past week. The Rox, under new president of baseball operations Paul DePodesta, acquired lefty Brennan Bernardino from the Red Sox last week. Bernardino, unlike Mushinski, is already on the 40-man roster. However, he’s the only established lefty reliever the Rockies have on the 40-man roster. Luis Peralta and Welinton Herrera are both on the 40-man, but Peralta has a 6.03 ERA in 31 MLB frames and Herrera has yet to pitch above Double-A.
