The Rangers claimed Contreras off waivers from the Angels on Thursday, Kiley McDaniel of ESPN.com reports.
Contreras looked in 2022 like he might be part of the Pirates' rotation for a while, but he's collected a 5.47 ERA and 111:63 K:BB over 136.2 innings since the start of the 2023 season and is now in his third organization since May. The righty mostly pitched in relief in 2024, but the Rangers could stretch him back out during spring training.
