The Arizona Diamondbacks and Colorado Rockies are both feeling upbeat for their weekend series in Denver, but for different reasons. Arizona ended a five-game road losing streak with a 9-5 win at Toronto on Thursday while Colorado, despite an extra-innings loss to Washington, heads home after a 4-3 road trip. Both will try to keep the good vibes going Friday night when the Diamondbacks send Zac Gallen (4-8, 5.19 ERA) against Rockies lefty Austin Gomber (0-0, 0.00) in the opener of the three-game series.
