The Rockies announced that they have selected the contract of right-handed pitcher Gavin Hollowell, while fellow righty Alex Colomé will go to the bereavement list in a corresponding move. The club already had a vacancy on their 40-man roster.
Hollowell, 24, was selected by the Rockies in the sixth round of the 2019 draft. He made an appearance in rookie ball that year before the minor leagues were canceled by the pandemic in 2020. He returned to official games in 2021, though was limited by injury to just 24 innings. He fared well in that limited action, largely in A-ball, putting up a 2.25 ERA with a 34.4% strikeout rate and 7.3% walk rate.
This year, he’s finally been able to have a normal season, throwing 48 2/3 innings out of the bullpen for the Double-A Hartford Yard Goats. In that time, he’s registered a 3.14 ERA with an excellent 34% strikeout rate and a strong 7.4% walk rate. Baseball America had Hollowell on their list of top 30 Colorado prospects both last year and coming into this year, complimenting his 95 MPH fastball and mid-80s power slurve. He’s also currently #40 on the Rockies’ list at FanGraphs.
With the Rox well out of contention and just over two weeks left on the schedule, the club can use that time to take a look at how Hollowell’s stuff plays in the big leagues. He’ll be making his major league debut as soon as he gets into a game.
