SAN DIEGO (AP) - Yasmany Tomas hit a three-run homer, Shelby Miller pitched 7 1/3 innings of four-hit ball and the Arizona Diamondbacks routed the San Diego Padres 11-2 on Tuesday night.
The Padres lost their fifth straight game. They were coming off a four-game sweep at Atlanta.
Miller (2-1) kept the Padres off balance most of the night, including four 1-2-3 innings, as he pitched into the eighth for the first time this season. San Diego broke through in the third with Wil Myers' two-out RBI single to center, but otherwise was frustrated.
Miller allowed a double to Travis Jankowski leading off the eighth, struck out Christian Bethancourt and then made way for Randall Delgado. Miller struck out five and walked two.
Chris Ianetta homered to right-center off Zach Lee in the eighth, his second.
Padres starter Jarred Cosart (0-1) left after 3 2/3 innings with a strained right hamstring.
