Hearn didn't factor into the decision in Saturday's 5-4 extra-inning win over the Mariners, giving up two unearned runs on three hits and a walk over 3.2 innings. He struck out three.
The 26-year-old still isn't fully stretched out and got the hook after 52 pitches (34 strikes), but after Kyle Seager took him deep in the first inning for a two-run blast, Hearn settled down and gave the Rangers a chance to rally. The lefty wraps up July with a 0.57 ERA, 0.64 WHIP and 13:5 K:BB through 15.2 innings over eight appearances, and he should remain in the rotation as long as he remains effective.
