The Rangers invited Heuer to spring training Thursday.
Heuer was not able to pitch in 2024 due to a fractured right elbow he suffered in 2023. He was only able to pitch in 12.2 inning during 2023 and he allowed 11 earned runs in his shortened season. The right-hander made his last MLB appearances in 2021, when he pitched for both Chicago teams. The veteran recorded a 4.28 ERA and 1.31 WHIP across 61.1 innings that season.
