PHOENIX -- A few days into the season, D-backs manager Kirk Gibson said that Juan Miranda would get the majority of the playing time at first base as the organization tries to figure out what it has in the young player.

On Friday, though, veteran Russell Branyan started for the third straight game and fifth overall compared to Miranda's four. While Gibson was circumspect in his reasoning, it appears it's just too tempting to have Branyan's bat in the lineup. Branyan entered play hitting .421 with a homer, in addition to playing good defense at first base.

Miranda, meanwhile, is hitting just .227, and his one homer and all three of his RBIs came as a pinch-hitter against the Cardinals on Tuesday night.

"Looking at the matchup tonight, I just thought it was a better matchup," Gibson said.

What about what he said about Miranda getting the majority of the playing time?

"That's probably the reason why I reserve a lot of the things I say," Gibson said. "You can always change your mind. Juan's going to get his playing time, but right now I felt this was the right way to go. Tomorrow it may be somebody different."

Shoulder tendinitis forces Heilman to DL

PHOENIX -- Aaron Heilman was fine with pitching through the discomfort in his shoulder, but when it started to affect the right-hander's performance, he knew something had to be done.

The D-backs placed Heilman on the 15-day disabled list Friday with tendinitis in his shoulder and recalled right-hander Josh Collmenter from Triple-A Reno.

For Heilman to experience any kind of injury is rare, as he has been a workhorse. The 32-year-old is the only pitcher in the Majors to have made at least 70 appearances in each of the last five seasons.

Heilman said he first felt discomfort when he tried to overthrow a pitch in his last start of Spring Training on March 27.

"It just got to the point where I couldn't pitch through it anymore," Heilman said. "I tried to pitch through it the last couple of weeks and felt that it was starting to affect my performance, and it's not fair to my teammates to go out there when you can't be effective."

After five years in the bullpen, Heilman tried to win a spot in the rotation this spring, but said he did not think the increased workload had anything to do with the injury.

In his last relief appearance Wednesday, he allowed six runs in 1 2/3 innings.

"Hopefully this is something we nip in the bud now," he said.

Collmenter gets first big league callup

PHOENIX -- Sleep did not come easy for Josh Collmenter on Thursday night.

The D-backs right-hander was informed earlier in the evening that he had been promoted from Triple-A Reno to the big leagues.

"Very excited -- it's the call you kind of wait for your entire career, so to get it is kind of an indescribable feeling," said Collmenter, who is getting his first taste of the Majors. "I tried to get as much [sleep] as I could. Besides the anticipation, half [was] not wanting to miss that alarm and miss the flight, so that kind of kept me on edge a little bit."

Collmenter, 25, made one start for Reno, allowing two runs (one earned) on two hits with seven strikeouts over six innings.

A 15th-round pick in the 2007 First-Year Player Draft, Collmenter has made a steady rise through the D-backs' farm system and was added to the club's 40-man roster this past offseason.

"My goal was move up a level every year," he said. "I didn't want to get stuck in that rut. You always have people coming from behind you and you have to keep proving yourself. It's a goal of mine not to let an opportunity slide by."

A starter throughout his Minor League career, Collmenter will pitch out of the bullpen for the D-backs, and he said his experience doing that in big league camp this spring will help.
