PHOENIX — Cody Ross homered and Wade Miley allowed five hits in seven innings to help the Arizona Diamondbacks beat the Tampa Bay Rays 6-1 on Tuesday night.
Miley (9-8) allowed one run, struck out five and walked two for his fifth win in his past six starts.
Eric Chavez had a pair of RBI doubles for the Diamondbacks, who pulled within five games of the Los Angeles Dodgers in the NL West.
Jeremy Hellickson (10-5) failed to pitch past the fifth inning for the second straight outing for the Rays, both against the Diamondbacks.
Hellickson gave up five runs and five hits and three walks, hit a batter and struck out one as the Rays slipped 1 1-2 games behind Boston in the AL East.
Tampa Bay went ahead 1-0 on Evan Longoria's 22nd home run with one out in the fourth, but Hellickson gave up the lead before recording an out in the bottom of the inning.
Paul Goldschmidt walked and scored on Chavez's double to left to tie the game 1-1. Hellickson then walked Aaron Hill before Ross, who entered the game 4 for 9 against the right-hander, homered to left to make it 4-1.
Arizona added a run in the fifth when Hellickson walked Goldschmidt and Chavez doubled off reliever Jamey Wright.
Martin Prado extended the lead to 6-1 with an RBI double to center, scoring Adam Eaton in the seventh inning.
