Zimmermann stays sharp, Tigers top Pirates 7-4

PITTSBURGH (AP) Jordan Zimmermann pitched six shutout innings, Nick Castellanos homered and drove in four runs and the Detroit Tigers remained unbeaten on the road with a 7-4 win over the Pittsburgh Pirates on Thursday.

Zimmermann (2-0), who signed a five-year, $110 million deal with Detroit last December, gave up six hits and two walks while striking out four. He has yet to give up a run for the Tigers, who won the final three games of the interleague series and improved to 4-0 away from Comerica Park.

Castellanos hit a two-run double in the fourth off Gerrit Cole (0-2) and added a two-run homer in the eighth off Tony Watson. Francisco Rodriguez pitched a perfect ninth for his second save.

Cole gave up two runs in six innings. He survived a scare when a liner from Zimmermann glanced off his head in the sixth.

The Tigers have scored at least four runs in each of their first eight games, tying for their best offensive start since 1913.
