LOS ANGELES (AP) Mike Bolsinger got out of the first inning on five pitches and three ground balls in his first big league start. Then he struck out four of his next five batters and was sailing along until the Los Angeles Dodgers figured him out the second time through the lineup.

The 26-year-old right-hander didn't make it through the fifth. By then, the defending NL West champions had turned a four-run deficit into a four-run lead for Dan Haren and went on to beat the Diamondbacks 8-6 - despite Martin Prado's two-run double in the eighth against Brian Wilson.

"The first time through the order was good, but I kind of got away from my game plan a little bit," Bolsinger said. "I left some balls up. And when you do that up here, there's consequences. It's how you respond to it. Each time I've been out there, I've kind of learned. I learned a lot from my first time out and I learned a lot from this start. Hopefully I can take it on to the next one."
