Cardinals pitcher Carlos Martinez was not at his best and was charged with second loss of the season Friday night against the Pirates in Pittsburgh.

Martinez allowed a three-run home run to Neil Walker in the seventh inning for his only damage of the night. He was charged with three runs on three hits and no walks in one inning of work. He owns a 4.19 ERA and a 1.19 WHIP in 19 1/3 innings.
