Cardinals pitcher Michael Wacha lasted only five innings in a no-decision Friday night against the Pirates.

Wacha survived an early injury scare, taking a comebacker off the ankle. Trainers came to check him out, but he remained in the game. He was charged with three runs on seven hits and one walk while striking out seven in five innings of a 6-4 defeat.

Over his three starts covering 17 1/3 innings, Wacha has allowed eight earned runs. He owns a 2.85 ERA, a 1.20 WHIP with 57:14 K:BB ratio in 47 1/3 innings. He'll make his next start Wednesday at home against the Cubs.
