DENVER -- There were superheroes in the D-backs' clubhouse Sunday morning.

In what is a tradition throughout baseball, the D-backs veterans had the rookies dress up in costume during the final road trip of the season. This year's theme was superheroes with players sporting costumes ranging from the Green Lantern to Superwoman.

The players walked from the team's hotel in downtown Denver to "The Delectable Egg," a popular breakfast spot nearby.

"Breakfast of champions," veteran reliever J.J. Putz said.

The presence of the players in costume drew quite a bit of attention among the fellow diners with kids asking to have their pictures taken with them.

"We had kids asking, 'Where's Iron Man?'" rookie catcher Tuffy Gosewisch said. "They were coming giving hugs. People were asking what's going on. It was just a good time."

The team originally was going to have the rookies dress up following last Thursday's game for the flight to Denver, but the Dodgers beat the D-backs that day to clinch the National League West.

"With everything that happened it wasn't appropriate timing," Putz said. "So we pretty much decided not to do it. The guys were all begging after the game yesterday, 'Hey can we just dress up tomorrow and walk to the field?' So we said yeah if you guys want to do it, we'll do it. We were going to bag it for this year."

D-backs manager Kirk Gibson came up with the line of the morning.

"Hopefully, they act like superheroes on the field," he said.

To help fielding, Cahill plans to tweak mechanics

ARI@COL: Cahill pitches a strong game vs. the Rockies

DENVER -- After being struck on the right hip by a line drive for the second time this year, D-backs right-hander Trevor Cahill said he will look to tweak his mechanics during the offseason so that he finishes his delivery in better position to field the ball.

"He's been hit a few times, you know, so it sounds like a good idea," Arizona manager Kirk Gibson said.

A bigger offseason project for Cahill and the D-backs will be to try and figure out how to eliminate the sudden loss of control that has happened to Cahill during his outings this year.

"When he doesn't walk guys he's pretty tough," Gibson said. "He cruises along and then he just loses it, and that's something I'd like to see him fix. We need to fix that together. We didn't get as much out of him as we needed to. He's capable of doing much better."

Cahill is 8-10 with a 4.02 ERA heading into his final start of the season Thursday against the Padres.

"With his stuff, I think he could win 20 games," Gibson said. "I really do."
