Dodgers pitcher Zack Greinke endured a rough outing as he dropped his first decision of the season Tuesday night against the Brewers.

Greinke, who made his second start since returning from a broken left collarbone, gave up nine hits, five earned runs and three walks -- all a season high --  in four innings of work against his former team. Greinke was traded to the Angels midseason in 2012 before signing with the Dodgers in the offseason.

"I didn't think about it at all," Greinke said. "Everything was bad, not just command. Just no feel out there, no adjustments to be made. Started out bad. I got out of some jams early but never really got better."

Greinke has allowed six runs in 9 1/3 innings of work since returning from injury. He will try to bounce back Monday at home against another former team -- the Angels.
