Colorado at Arizona

Colorado is on a 15-7 run behind a sizzling offense that is second in baseball in runs scored, and third in slugging. They've scored 73 runs the last eight games, off an 8-1 rout of Arizona yesterday as a +140 dog. The Rockies are 10-4 against a right-handed starter, plus 11-1 versus a starter with a WHIP less than 1.15. Arizona has a losing home record and has lost three of five allowing 33 runs. The Diamondbacks are 1-7 against the NL West, plus 2-5 when Zack Greinke works on five days of rest. With Colorado 16-5 in the last 21 meetings, back the red hot underdog and play Colorado.
