Hearn didn't factor into the decision Monday against the Rockies after tossing four innings of one-run ball, allowing eight hits and a walk while fanning six.
The 27-year-old southpaw gave up plenty of contact despite tossing 54 of his 76 pitches for strikes, but at least he found a way to limit the damage. Hearn, who didn't see action in the Rangers' opening series against the Blue Jays last week, is projected to have a two-start week since he's scheduled to make his second start April 17 against the Angels in Arlington.
