Cardinals pitcher Michael Wacha turned in a decent outing on Sunday, and came away with his second win of the season in his team's 6-4 victory over the Cubs.

Wacha (2-0) surrendered a two-run home run to Anthony Rizzo in the opening frame and a run-scoring single to Welington Castillo in the fourth. He was charged with three runs on five hits and one walk while striking out eight over 6 1/3 innings pitched.

Wacha has allowed just four earned runs over his first 19 innings pitched through three starts. He'll look for win No. 3 Friday on the road against Washington.
