Clayton was relieved with one out in the sixth by Ian Ekery, who inherited runners on the corners. Ekery induced two fly balls to escape the jam, and threw 2 2/3 innings of scoreless relief to record the win.
Closer Andrew Lines earned the save with a perfect top of the ninth.
"My job was to come in, keep the ball down," Ekery said. "My ideal job was to get an inning-ending double play, but as long as we got out of there without any runs, that's just the main job. To get out of there with no more damage."
