The Arizona Diamondbacks took a 13-2 beating here at Coors Field Monday night and have now lost three in a row and eight of their last 10. The Rockies lead the National League West by 1 1/2 games with the Diamondbacks in third place, 3 1/2 games back and the Dodgers sandwiched in between.

Arizona needs to get it together ASAP if it wants to make it to the postseason, and it should get an important win here with Zack Greinke on the mound.

Greinke (13-9, 3.08 ERA) is 2-0 with a 2.33 ERA in three outings against Colorado this season and he owns a 4-1 behind a 4.20 ERA in 11 career games (10 starts) at Coors Field.

The Rockies counter with Antonio Senzatela (4-5, 4.92 ERA). He is 0-2, 6.75 in two games (one start) against the Diamondbacks this season and 0-3, 8.27 against them in six career games (two starts). He's 2-4, 4.47 in nine starts since returning to the rotation July 3.
