Lots of reasons
Cubs are 3-15 vs. lefties and
Cube are 10-28 on the road
Plus last game of a road trip
Plus their horrid bullpen is exhausted
And to top it all off Ump Scott Barry calling balls and strikes and home teams are 11-3
D'backs ML to win a dime
D'backs RL risking 500 to win 685
Let's nail this one
