The Arizona Diamondbacks are holding a firm grip of the top Wild Card in the National League. They're coming off three straight victories and defeated the Giants 3-2 here at AT&T Park Friday night.

Tonight Zack Greinke (16-6, 2.99 ERA) will take the ball for the D'Backs. He's allowed just six runs in 26 2/3 innings through his last four starts overall, and he's 10-2 against the Giants in his career behind a 2.56 ERA in 16 starts.

The Giants' left-hander Madison Bumgarner (3-8, 3.55 ERA) has been tagged with 11 runs on 15 hits in 11 innings through his last two starts overall. The Giants have lost each of his last four starts overall and they're 0-8 in Bumgarners' last eight starts against team from the National League West division.

My selection in this matchup between a pair of aces is an 8* play on Arizona Diamondbacks.
