The Rockies have agreed to a minor league contract with free-agent righty Geoff Hartlieb, per the team’s transaction log at MLB.com. The former Pirates and Mets reliever, a client of Paragon Sports International, will presumably head to spring training as a non-roster invitee.
Hartlieb, 29, spent the 2023 season in the Marlins organization and tossed four innings of one-run ball in the Majors. The rest of his season was spent in Triple-A Jacksonville, where he notched a solid 3.63 ERA with a 23.8% strikeout rate, 9.3% walk rate and 47.6% ground-ball rate in 44 2/3 innings of bullpen work.
Through parts of four Major League seasons, Hartlieb has been tagged for a 7.17 ERA in 70 1/3 innings, due largely to lackluster command. He’s averaged better than 96 mph on his four-seamer and better than 94 mph on his sinker, generating grounders at a healthy 49% rate and missing enough bats (20.4% strikeout rate) to get by if he could pare down the free passes. Hartlieb, however, has walked 15.1% of his opponents in the Majors, which has unsurprisingly proven untenable.
The Rockies have minimal certainty in their bullpen and figure to have multiple spots up for grabs heading into the 2024 season. It stands to reason that Hartlieb will be one of many experienced bullpen options brought in on minimal or no-commitment deals such as this one. He’s out of minor league options, so if he cracks the big league roster at any point, he’ll have to stick in the Majors or else be designated for assignment and exposed to waivers.
