Saturday night's Rockies-Reds game was postponed because of a broken water main at 20th and Blake -- the intersection where Coors Field is located. The Denver Office of Emergency Management requested the game be postponed at about 6:50 p.m., or about 40 minutes after the scheduled start time. The water main break at 20th and Blake cut off the water supply to the ballpark, meaning the restrooms and concession stands were "inoperable," the team said in a press release. The game will be made up Sunday at 7:10 p.m. MT as part of a split doubleheader. The Rockies and Reds also will play at 2:10 p.m. MT. That game is expected to be a sellout because of jersey retirement ceremonies for Rockies longtime star Todd Helton, who played 17 seasons in a Rockies uniform before retiring at the end of last season. In Sunday's first game, the Reds will start right-hander Mat Latos (4-3, 2.95 ERA) against Rockies right-hander Jordan Lyles (6-1, 3.70). The second game will pit Reds right-hander Dylan Axelrod in his 2014 debut against Rockies lefty Yohan Flande (0-5, 5.36). The Rockies also have some lineup uncertainty. First baseman Justin Morneau suffered neck stiffness on Saturday and was scratched from the lineup.
