DENVER -- Outfielder Charlie Blackmon was reinstated from the 15-day disabled list and optioned to Triple-A Colorado Springs on Saturday. Before Friday, he had last played on March 19, and was sidelined with a severe case of turf toe on his left big toe.

Blackmon made his 2012 debut for Colorado Springs on Friday, and went 1-for-4 with three strikeouts. He was also 1-for-4 on Saturday.

At the time of his injury, Blackmon was vying with Tyler Colvin for a reserve outfielder job. Colvin proceeded to finish the spring strong, though manager Jim Tracy said Blackmon "was in a good place" at the time of his injury.

Tracy said Blackmon has made adjustments on both offense and defense that have helped him. He is standing less erect at the plate, Tracy said, and has learned to incorporate the lower half of his body in his swing, which helps him drive the ball more. On defense, Tracy said Blackmon has gotten more aggressive on balls that are in front of him.

"This is a guy, believe me, I think as we go through the course of the season, is going to be helpful to our club," Tracy said.

CarGo sits out with strep throat

DENVER -- Left fielder Carlos Gonzalez, who played Friday with strep throat and went 2-for-5, was not in the lineup Saturday.

Asked if Gonzalez was completely unavailable on Saturday, Manager Jim Tracy said, "I won't pin myself down 100 percent, but I would probably say that there's a strong chance that he would be unavailable."

Tyler Colvin replaced Gonzalez in left field, and hit a two-run homer in his first at-bat. His other start this season was in center field, last Sunday in Houston. Troy Tulowitzki moved from fourth to third in the batting order, with Todd Helton and Michael Cuddyer moving up one spot, from fifth and sixth to fourth and fifth.

Pomeranz set to make debut on Sunday

DENVER -- Left-hander Drew Pomeranz is scheduled to make his 2012 debut for the Rockies and start on Sunday, when they first need a fifth starter. However, bad weather is forecast for Sunday, which could delay him.

"I'm already on a weird schedule anyway," said Pomeranz, who is no stranger to disruptions.

He couldn't officially be traded to the Rockies last year until Aug. 17, the one-year anniversary of signing his first professional contract. So when the Indians included Pomeranz in the July 31 deal that sent pitcher Ubaldo Jimenez to Cleveland, Pomeranz had to go to the Indians complex in Goodyear, Ariz., and work out for two-plus weeks.

Three days after his first start for Double-A Tulsa, Pomeranz underwent an emergency appendectomy, which sidelined him until Tulsa's final regular season game. "I just tell myself to get used to weird schedules," Pomeranz said. "Whatever's going to happen is going to happen; I just got to be prepared."

Pomeranz threw 77 pitches in four scoreless innings on Tuesday. Coupled with his two starts for Tulsa last year, Pomeranz has pitched 14 innings for Tulsa without allowing a run or a walk, giving up six hits with 11 strikeouts in that span.

Pomeranz, 23, went 2-1 with a 5.40 ERA for the Rockies in four September starts, three of them very good. Manager Jim Tracy said the biggest difference in Pomeranz this year is he's in ideal health and at full strength.

"There's more life to his pitches than when he was competing for us last September," Tracy said. "There's no getting around the fact he had a tremendous Spring Training."

Tracy gets Pacheco in lineup on Saturday

DENVER -- In his first two starts, Jordan Pacheco batted second and played third base last Sunday, and hit seventh while playing first base on Thursday. Manager Jim Tracy, wanting to keep Pacheco in the mix, started him at third base and hit him eighth on Saturday, a difficult spot for a young hitter with the pitcher behind him.

"The eight hole when you're trying to break in a young player is a difficult spot in the lineup," Tracy said. "He has tremendous plate discipline, and the other thing is his awareness to situations, and what it is that's taking place as the at-bat is unfolding.

Rogers pitching well out of bullpen

DENVER -- Reliever Esmil Rogers has pitched 3 2/3 scoreless innings in his past two games, with no walks and five strikeouts. He relieved struggling starter Juan Nicasio in the third inning on Friday, with two outs and runners on first and second, and got Willie Bloomquist to ground out.

In the fourth, Rogers put runners on second and third with no outs and escaped, striking out Chris Young and Paul Goldschmidt for the final two outs.

Rogers has not allowed a run in 5 2/3 innings this year, but in his first outing on Monday against the Giants, he gave up three hits and two walks in two innings. Bullpen coach Jim Wright helped Rogers make a mechanical change when he was throwing in the bullpen that stopped him from being so rotational with his upper half.

Wright told Rogers he was not quick enough getting his arm back. And then he put his hands on Rogers' shoulders, shook him from side to side and asked Rogers if he got tired of moving that way all the time.

"I said, 'What you're doing is throwing around your left shoulder,'" Wright said. "I said, 'I want you to think about what it means to throw over the front shoulder.' He threw two throws, he looked at me and he said, 'I got it.' And that was basically it."

Worth noting

• The Rockies hit back-to-back homers for the first time this season when Tyler Colvin and Ramon Hernandez went deep in the second.

• Second baseman Marco Scutaro entered the game just 5-for-27, but he had not yet struck out.

• The start of the game was delayed 16 minutes by rain.
