The impromptu postponement did help out a few banged-up sluggers. Reds first baseman Todd Frazier was going to take a second night off with a strained lower back.
For the Rockies, first baseman Justin Morneau was a late scratch with a stiff neck.
The Rockies will retire Todd Helton's No. 17 in a ceremony Sunday. The longtime first baseman wrapped up his 17-year career in the Mile High City last season, departing as the franchise's career leader in games played (2,247), hits (2,519), doubles (592), homers (369) and RBIs (1,406).
Helton will be the center of attention, something he never really craved during his career.
"He's going to have all the eyes on him," said outfielder Michael Cuddyer, who was activated off the disabled list Saturday after missing more than two months. "I know he's going to feel awkward, but he deserves to feel awkward."
Cuddyer firmly believes Helton belongs in Cooperstown.
"He's a Hall of Famer," Cuddyer said. "I'd put his numbers up to anybody's. He's up there with them."
Reds: INF Brandon Phillips (left thumb) was 0 for 2 with a walk and played seven innings during a rehab game with Triple-A Louisville on Friday. Price wants to see how the rest of the weekend goes for Phillips before making any decisions on when he might rejoin the team. "We're anxious to have him back," Price said.
Rockies: LHP Franklin Morales missed his start Friday when his wife went into labor. Morales proudly announced his wife had a girl they named Mariana Elena. She was born at 5:37 p.m. Friday and weighed 6 pounds, 11 ounces.
Reds: RHP Mat Latos (4-3) will start the first game and RHP Dylan Axelrod the second. Axelrod is taking the place of Homer Bailey, who was placed on the 15-day disabled list Saturday with a strained right elbow.
Rockies: RHP Jordan Lyles (6-1) gets the ball in the afternoon contest and LHP Yohan Flande (0-5) will go that night. Flande will try for his first major league win in his eighth start.
