CINCINNATI -- Just about everything right now is a new experience for D-backs right-hander Josh Collmenter. After making 91 starts in the Minors, he's getting his first taste of big league life, and is working as a full-time reliever for the first time.

"I had some sunflower seeds in the bullpen [on Sunday]," Collmenter said. "I never had sunflower seeds during a game when I was starting. It's getting used to doing different things. Good thing I'm not that superstitious about stuff."

Collmenter, 25, made his Major League debut on Sunday and earned his first career victory in the D-backs' 6-5, 12-inning win over the Giants. He pitched two perfect innings with two strikeouts and secured a couple of baseballs and the lineup card for his trophy case.

Although Collmenter pitched out of the bullpen in Spring Training, he's still getting acclimated to the role, particularly when it comes to his pregame preparation.

"It's such a quick rush," he said. "That makes it pretty exciting. You're just a phone call away. As a starter you have so much more preparation."

Manager Kirk Gibson likes what he's seen from Collmenter, on and off the mound.

"His arm angle is really funky," Gibson said. "He did a really good job [on Sunday] of establishing his changeup early on, and his fastball was really effective after that. He's got a lot of character. He's not shy. He's just a very confident kid."

Mora out of lineup with jammed foot

CINCINNATI -- D-backs third baseman Melvin Mora was in Tuesday night's starting lineup when it was first released, but he was scratched moments later.

According to manager Kirk Gibson, Mora was still feeling the effects of jamming his left foot into the first base bag after grounding out as a pinch-hitter in Sunday's win over the Giants.

"He went out and warmed up ... he was still a little sore," Gibson said. "We wanted to make sure he's OK. He could be available to pinch-hit."

Mora is batting .281 in 11 games, including eight starts at third.

Ryan Roberts, who is hitting .355, is making his seventh start at third and batting second on Tuesday night in Mora's absence.

In other lineup news, catcher Miguel Montero was moved back to sixth after batting eighth on Sunday. Juan Miranda made his sixth start at first base, batting eighth.

Gibson sees change in clubhouse

CINCINNATI -- D-backs manager Kirk Gibson has seen signs of a shift in the culture surrounding his ballclub.

One example was seeing a jam-packed visitor's weight room at Great American Ball Park during Monday's off-day.

"These are the types of things we talked about coming into Spring Training," Gibson said. "I believe in not focusing on negative things. We want more success, I know that. We'll keep pushing ahead."

Gibson said he'd prefer not to dwell on the past, in particular the D-backs' 25-56 record last season on the road. This season, the club is 2-3 on the road heading into the start of a six-game road trip in Cincinnati.

One shift in attitude he tried to instill in Spring Training was not getting too high or too low over the long haul of a six-month season. Celebrations like Sunday's walk-off win over the Giants should be savored, but brief, he said.

"You have quick celebrations and you move on," Gibson said. "You've got to be scared to death to keep it going. Every day is a new day."

Worth noting

Josh Collmenter's first career victory on Sunday was historic on several levels. He is the fourth D-backs pitcher to toss at least two scoreless innings in his Major League debut, and just the second to not allow a hit in his debut over at least two innings. Collmenter is the seventh pitcher in Arizona history to earn the victory in his first career outing, and the first to do so at home. According to the Elias Sports Bureau, Collmenter is the only relief pitcher to win his big league debut against a defending World Series champion club.
