ANAHEIM -- Hard at work before Tuesday's game against the A's, Mark Trumbo could be seen on the field at Angel Stadium hours before first pitch, taking ground balls at third base.

Trumbo wasn't in the team's starting lineup for the second straight night, but manager Mike Scioscia insists Trumbo will get his chances.

"He'll get in there," Scioscia said. "We have some things that we are looking at. Mark had a great workout at third base today and he will get in there.

"He'll get starts at first, third, left, right and designated hitter. Right now, some guys look like they are going to break out that we just want to keep in the lineup."

On Tuesday, Trumbo specifically worked on his approach to the ball at third base and how to present his glove, while Scioscia and coaches Alfredo Griffin and Rob Picciolo looked on. It's a routine he's begun doing three to four times a week.

"I want them to be comfortable putting me out there. I am putting so much emphasis on putting the work in to try and give myself the best chance to make those plays," Trumbo said. "I need to make those plays to be at third. If I can't make the routine play, I don't belong there."

In his three starts at third -- he's also started twice at DH -- Trumbo has committed three errors.

He's done especially well at the plate though, batting .375 with two home runs and three RBIs to begin the season.

"My confidence has to remain high at third," Trumbo said. "Whether or not I am getting the results, I have to go in mentally thinking I am the best third baseman in the game.

"I didn't expect it to be easy. It is tremendously challenging. I expected it to be difficult, and at times it has been."

Carpenter eager to make impression on Halos

ANAHEIM -- Still taking it all in as he adjusts to pitching at the Major League level, Angels reliever David Carpenter is just happy to be with the team.

Called up by the Angels on Friday, Carpenter made his Major League debut for the team later that night, tossing a scoreless ninth inning against the Yankees.

"It really is a dream come true," Carpenter said. "I really want to show in each outing why I deserve to stay here."

In two appearances this season, both against the Yankees, Carpenter has tossed a a total of three innings, giving up two runs on two hits, while walking two and striking out one.

More than anything, the organization likes the makeup of the 24-year-old right-hander.

"In the few outings he's had here, he hasn't been intimidated," Angels manager Mike Scioscia said. "He has some deception to his delivery and has a good sinker. That should play well for a guy slotted somewhere in the middle of the bullpen right now.

"He'll get a chance to contribute. That's for sure."

Angels keep Kendrys in mind for time at first

ANAHEIM -- While the Angels are set at first base with Albert Pujols, the team hasn't ruled out Kendrys Morales playing the position sometime this season, manager Mike Scioscia said Tuesday.

"He isn't an option to play defense right now unless it is an emergency, but at some point this year you'll see him available and playing first base," Scioscia said.

However, Morales isn't there yet. With Morales taking ground balls at first base since the beginning of the season, the Angels want to make sure he goes at his own pace.

"It isn't something we are saying we need to do. It is something that will happen in its own time," Scioscia said. "We just want the availability if a player would have to miss a month or so."

Morales last played first base on May 29, 2010, against the Mariners, the game in which he broke his ankle when celebrating a walk-off grand slam.

"A lot goes into being able to play first base," Scioscia said. "You have to push off to hold the runner, make throws to second and you just need an overall agility. That is a little further down the road.

"We are going to let him go at his own pace and hopefully it won't have to happen this year. He can go out comfortably right now and take ground balls, we just don't have a need for it."
