Arizona at Colorado

Arizona has scored 34 runs in the last five games, winning three of them. Starter Zac Gallen (3.32 ERA) goes here, and he shut out Colorado, 4-0, in May. The Diamondbacks have also won eight of his last 12 starts. Colorado is on a 4-7 run and is saddled by a pitching staff that is 28th in team ERA (4.98) and a relief staff that is second-worst in the Majors (4.81 ERA). Colorado is 18-37 against teams that strand 6.9 or fewer runners per game, as well. Arizona has won five of the last seven meetings, including wins of 4-1 and 4-0 earlier this season. The wagering value is on the visitors to win again by more than one run. Play Arizona on the runline.
