In Phoenix, Luis Castillo struck out eight over six-and-two-thirds innings of shutout ball to help the Reds blank the Diamondbacks 7-0.
Castillo allowed just three hits on the way to his first big league victory. Joey Votto keyed the offense with a home run and three RBI. Scooter Gennett and Tucker Barnhart also went deep in the winning effort.
Taijuan Walker surrendered five runs over five innings of work to take the loss for the D'Backs. Arizona has dropped four-of-five.
Reds manager Bryan Price says Castillo did a nice job of keeping the Diamondbacks off balance.
And the Indians blanked the Tigers.
Mike Clevinger and two relievers combined on a four-hit shutout as the Indians topped the Tigers, 4-0, in Cleveland.
Clevinger allowed three hits over six scoreless innings for his fifth win. The Tribe pulled away with a three-run eighth inning, highlighted by a Bradley Zimmer RBI-triple. Cleveland has won three straight games and needs another to sweep the Tigers.
Justin Verlander allowed a run over six-and-two-thirds to take the loss for Detroit. J.D. Martinez had the only extra base hit for the Tigers, who have lost five-of-seven.
