PHOENIX (AP) — Arizona's Cody Ross hit a sacrifice fly to drive in the winning run in the bottom of the 10th inning, lifting the Diamondbacks to a 3-2 win over the Colorado Rockies on Saturday, closing the gap between the National League West's top teams back to one game.
A.J. Pollock led off the inning with a single, stole second and moved to third on a throwing error. After a walk, Ross hit his fly ball more than 400 feet to center field, giving the Rockies no chance to throw out the speedy Pollock.
