The Rangers selected Quantrill's contract from Triple-A Round Rock on Wednesday, Kennedi Landry of MLB.com reports. Quantrill has made three starts at Round Rock so far this year and owns a 5.14 ERA and 1.07 WHIP through 14 innings. The Rangers are short on bullpen arms after losing Chris Martin (biceps) and Luis Curvelo (shoulder) to the injured list Wednesday, so Quantrill could be tapped for long-relief duties while in the majors.
The Rangers reassigned Quantrill to minor-league camp Wednesday. The Rangers closed out spring training with the top four members of the rotation all in optimal health, and with Kumar Rocker pitching well enough to beat out Jacob Latz for the fifth and final spot, Quantrill never made much of a run at securing a starting role while he attended camp as a non-roster invitee. He'll serve as organization pitching depth for the Rangers this season and will likely slot into the rotation at Round Rock.
Quantrill signed a minor-league deal with the Rangers on Thursday, which includes an invitation to spring training, Evan Grant of The Dallas Morning News reports. Quantrill closed the 2025 season in the Rangers' organization, making two starts at Triple-A Round Rock. He looks unlikely to break camp in the rotation, but he could make an impact at some point in the new campaign.
