Two major reasons why I like the Under in this matchup: Cubs starter Javier Assad and the weather, primarily the wind. It's going to be blowing in at 10-15 mph.

Assad has been fantastic in going 3-2 with a 2.69 ERA in seven starts. He's been super sharp in his last three starts with a 1.33 ERA and 0.98 WHIP. The key Cubs' relievers are rested, including closer Adbert Alzolay.

Arizona scored 12 runs on the hapless Rockies at home yesterday. Previously to that, however, the Diamondbacks had averaged 2.8 runs in their last eight games. Arizona also might be without dynamic rookie Corbin Carroll, who left Wednesday's game with a bruised wrist after being hit by a pitch.

Ryne Nelson gets the start for Arizona. He's been respectable on the road with a 4-2 record and 3.30 ERA.
