The doubleheader was scheduled when heavy snow began falling in the second inning Wednesday night and caused that game to be wiped out.
Colorado third baseman Matt Holliday paced the clubhouse from the time the groundskeepers put the tarp back onto the field Thursday until the postponement was announced an hour before the scheduled first pitch of the opener. Rain was falling and the temperature was 37 degrees.
The doubleheader was rescheduled for Aug. 8, which had been an off day for both teams.
"I'm ready to play," Holliday said. "I wanted to play."
Holliday went right to the video room and began preparation for Odalis Perez, the scheduled starter for the Dodgers on Friday, when the Rockies open a series in Los Angeles.
"He is a smart young man," Colorado manager Clint Hurdle said. "And a very mature one."
Holliday is hitting .321 with four triples and 14 RBI. Last year, he batted .290 with 14 home runs and 57 RBI.
"I'm maturing as a hitter, one that has gotten out away from the mode of trying to pull everything," Holliday said. "Today I stay back and look for pitches away especially when I fall behind in the count and you expect to see breaking balls away."
Holliday's progress helped allow the Rockies to trade Larry Walker to St. Louis.
"He's a smart hitter and become a good two-strike hitter," Hurdle said. "And he becoming a better fielder."
- Florida pushed back starter A.J. Burnett to Friday in Philadelphia. Dontrelle Willis replaced Brian Moehler as Saturday's starter and Josh Beckett will work Sunday against the Phillies.
- Jason Jennings will start for Colorado on Friday at Los Angeles, Joe Kennedy on Saturday and Shawn Chacon on Sunday. The Rockies will follow with Jeff Francis, Jamey Wright and Jennings in San Diego. "That way we give Chacon another day of rest and we split the left-handers," Hurdle said, referring to Kennedy and Francis.
- Rockies RHP Aaron Cook is to throw a 50-pitch simulated game Friday in Tucson.
- The Rockies purchased the contract of RHP Jay Witasick from Colorado Springs, optioned RHP Scott Dohmann and RHP Ryan Speier to their Triple-A farm team and activated OF Dustan Mohr from the DL.
