DENVER -- First baseman Todd Helton was not in the lineup on Sunday for the sixth time in seven games due to back stiffness.
He missed four straight games before playing on Friday, but didn't play Saturday. Manager Jim Tracy said, "Todd's doing better, but he's still a little bit stiff. We just don't want to do anything to aggravate [it]. Like Tulowitzki, I really believe you're going to see some more of Todd, but I want him to feel better."
Helton, 38, has had a highly successful season. He's hitting .303 with 27 doubles, 14 homers and 69 RBIs in 123 games. Additionally, Helton's on-base percentage is .384 and his slugging percentage is .468.
"It's unfair to compromise Todd Helton with what he has done and the body of work that he has given us," Tracy said. "It's unfair to compromise him by sending him out there stiff and sore."
Field stunned to make surprise MLB debut
DENVER -- Infielder Tommy Field, who spent the season at Double-A Tulsa, found himself at Coors Field for the first time Sunday, hitting eighth in the Rockies' lineup and playing shortstop in his Major League debut because of minor injuries to various infielders.
Field was stunned to join the Rockies and said he had "no idea" he would start.
Shortstop Troy Tulowitzki was out with a sore left hip after playing Saturday, soreness that had kept him from playing Friday. Manager Jim Tracy wanted to rest Tulowitzki because he would have two days off with the Rockies not playing Monday. Tracy said Tulowitzki would be ready to play Tuesday at Milwaukee, where Tracy wants to use his most competitive lineup since the Brewers are trying to hold off the Cardinals in the National League Central.
Infielder Chris Nelson, who played shortstop in the Majors for the first time on Friday, came into the clubhouse Sunday with a protective boot on his left heel. Heel soreness bothered Nelson at the end of the Triple-A Colorado Springs season and delayed his activation to the Rockies until Friday, three days after he was brought up.
Also, second baseman Mark Ellis was hit in the back of the helmet and neck with a pitch on Saturday thrown by Reds reliever Carlos Fisher. Ellis had neck soreness Sunday, but no concussion symptoms or headache. As a precaution, Tracy didn't want to start Ellis but said he might be available to play defense.
Field, 24, who was in big league Spring Training this year with the Rockies, hit .271 at Tulsa with 17 home runs and 61 RBIs. He primarily played second base this year, but has extensive experience at shortstop.
Field said he was in Oklahoma on Saturday attending a reunion of his wife's family, and was driving back to their home in Waco, Texas, when a member of the Rockies Minor League department called and said Field might be going to the big leagues.
"We all kind of held our breaths ... finally got the call around midnight," Field said. "They booked, I guess, the first flight they could find out of Dallas. It was at 7 this morning. We ended up leaving Waco, which is about two hours away, at 3:45 to get there.
"It's pretty surreal, and I'm really excited to be here."
White joins Mussina, Wakefield in record books
DENVER -- Alex White was the winning pitcher Saturday despite allowing five home runs in five innings. He gave up seven runs, six earned, in five innings in the Rockies 12-7 victory.
According to the Elias Sports Bureau, White is only the third pitcher in Major League history to get a win in a game in which he has allowed at least five homers in no more than five innings pitched.
Mike Mussina did it for the Orioles against the Angels on July 1, 1994 -- five homers in five innings -- and knuckleball specialist Tim Wakefield did it for the Red Sox at Detroit on Aug. 8, 2005, when he allowed six homers in five innings.
Rockies shuffle roster for Pomeranz, Field
DENVER -- To make room on the 40-man roster for infielder Tommy Field and pitcher Drew Pomeranz, who made his Major League debut on Sunday, the Rockies designated Triple-A Colorado Springs catcher Tom Pagnozzi for assignment and placed outfielder Ryan Spilborghs on the 60-day disabled list with planter faciitis in his right heel.
Spilborghs had been on the 15-day disabled list with that injury from Aug. 5 until Sept. 2. He played in three games, including two starts, but after he reaggravated the injury on Sept. 5, Tracy announced that he wouldn't play the balance of the season.
Drew Pomeranz, who made his major league debut, is the 13th pitcher to start for the Rockies this season.
Right fielder Carlos Gonzalez was scratched from the lineup with lower back stiffness.
Jordan Pacheco gave the ball he hit for his first major league home run Saturday to his father, Joe, after the game. Pacheco said he flipped the ball to his father, who said, "What's this?"
"It's the home run ball," Pacheco said. To which his father replied, "Good job. Better do it again tomorrow."
