Clarke gave up two runs (one earned) on four hits and two walks over four innings in a no-decision versus the Rockies. He struck out four.
Clarke was called on for the start after Merrill Kelly was scratched with a shoulder injury. The 27-year-old Clarke did fairly well on short notice. He's posted a 2.33 ERA and 1.09 WHIP with 18 strikeouts in 19.1 innings in seven appearances, six of which have been in relief. Clarke could be in for another start this weekend while Kelly remains out.
