Cardinals pitcher Adam Wainwright fell on the wrong end of a pitcher's duel on Sunday, suffering his first loss of the season in a 2-1 defeat to Pittsburgh.

Wainwright (1-1) allowed run-scoring doubles to Neil Walker and Tony Sanchez for his only blemish of the afternoon. He was charged with only two runs on five hits and two walks while striking out seven in seven innings of work. He tossed 100 pitches, 65 of which were strikes.

Wainwright has allowed just two run over 14 innings pitched this season. He'll look to keep rolling on Saturday at home against the Cubs.
