Wainwright (5-4) went seven innings against the Giants on Friday, and allowed only two runs on five hits and a walk while fanning six.
Wainwright was sharp, but he was outdueled by Johnny Cueto. Despite the loss, the 34-year-old lowered his ERA for the fourth consecutive game, and he registered a season-high mark for strikeouts. Moreover, Wainwright has done a good job keeping the ball in the park recently, having gone without allowing a long ball in three of his last four starts. He'll face the Reds in Cincinnati on Thursday in his next scheduled start.
