I've been swinging well, and the coaches have helped me a ton, the hitters have helped me a ton. I'm like a kid in a candy store right now. I'm the happiest I could ever be right now."
Travis Wood was the last pitcher to deliver a go-ahead RBI in extras, with his bases-loaded walk against Milwaukee on May 18. Before that, the last pitcher who delivered an extra-innings, go-ahead hit was Florida's (now Miami) Burke Badenhop on May 16, 2011. It was an RBI single that gave the Marlins a 2-1 lead vs. the Mets in the top 11th.
Wainwright, following the big hit, is batting .261 with four doubles, one triple and one home run on the season.
