Houston at Arizona

The Astros need to win and have ace Dallas Keuchel (19-8, 2.47 ERA) going, but hold on: he is 4-8 with a 3.82 ERA in 14 road starts. Keuchel is also just 2-2 with a 4.13 ERA in four career starts against Arizona. The Astros are 16-40 in their last 56 road games, plus 1-5 in Keuchel's last six road starts. They face a terrific Arizona offense anchored by star Paul Goldschmidt, with the team eighth in on-base percentage, and seventh in runs scored. The Diamondbacks have won four consecutive games and five of their last six. Diamondbacks starter Rubby De La Rosa (14-8) has won his past two starts and is 7-3 at home this season. Houston is 8-18 on the road against a right-handed starter, while the Diamondbacks are 9-4 in De La Rosa's last 13 starts. With the Astros on a 7-19 run at Arizona, so jump on the hot home dog and play Arizona.
