With the departure of Zack Greinke, the Arizona Diamondbacks new ace is southpaw Robbie Ray and he will be tapping the rubber tonight when Arizona opens a 3-game set with the Washington Nationals at Chase Field. Ray is 9-7, with a 3.91 ERA, a 1.30 WHIP, and the Diamondbacks are 4-1 in his last 5 starts. The Nationals are expected to send Joe Ross to the hill. Ross has pitched mainly out of the bullpen and his numbers are not good. He is 0-3, with a 9.85 ERA, a 2.11 WHIP, and he was lit up in his last start, yielding 7 runs on 9 hits to the Los Angeles Dodgers. Washington has had problems with left-handed starters on the road, going just 4-11 in their last 15.
TONIGHT’S PICK: ARIZONA DIAMONDBACKS
