Arizona at Colorado

Arizona has won four of six after its 9-1 victory over the Rockies on Friday night. Ildemaro Vargas continued his sensational season as he went 4-for-5 with a double and two RBIs, and Merrill Kelly pitched a complete game. The Diamondbacks are on a 7-2 UNDER run, and they have allowed one or no runs in five of those games. Six of their past seven games at Coors Field have stayed UNDER. Arizona has won 10 of the past 15 meetings, and Colorado has lost seven of its past eight home contests. The Rockies are 1-5 and have scored more than three runs once in their past six games. Eduardo Rodriguez is 4-0 with a 2.25 ERA, and Arizona has won his past six starts. He comes off a 5-1 win over the Mets when he allowed one run on four hits in 8 1/3 innings. Take the Diamondbacks and the UNDER.
