Hearn agreed to a one-year contract with the Rangers on Friday to avoid arbitration.
Hearn worked as a swingman for the Rangers last season with 13 starts in 31 appearances, and he had a 5.13 ERA, 1.50 WHIP and 97:43 K:BB across 100 innings. Texas has significantly revamped its rotation during the offseason, so the 28-year-old will likely be limited to a relief role in 2023.
