CLEVELAND -- Major League Baseball announced the winners of the 2013 Honorary Bat Girl Contest on Wednesday, and Kristin Frost has been chosen to represent the A's.

A mother of two young girls, Frost was diagnosed with Stage III breast cancer on Sept. 17, 2012. She said that baseball plays a big role in her house, where Stomper, the A's mascot, is a favorite.

"I had to face this cancer and the world head-on with all my strength, for I was going to persevere, win and thrive, for I am a fighting Momma," Frost wrote in a press release. She is expected to continue with radiation for another two weeks.

Since the A's will be on the road this Mother's Day, Frost will be recognized by the club later in May. She'll participate in pregame activities, be honored during an on-field ceremony and receive pink MLB merchandise and two game tickets.

The program, which was introduced in 2009, raises additional awareness and support for the annual "Going to Bat Against Breast Cancer" initiative, celebrated every Mother's Day. Frost is one of many fans across the country who shared inspirational stories about hope and motivation in the fight against breast cancer, in addition to why they or their nominee should represent their favorite team.

Frost and the 29 other honorary bat girls were selected through fan votes on HonoraryBatGirl.com, along with feedback from a judging panel that included CC Sabathia of the Yankees, Matt Kemp of the Dodgers, Andrew McCutchen of the Pirates, Alex Gordon of the Royals, Maria Menounos of Extra TV and Sam Ryan of MLB Network.

On Mother's Day, players and on-field personnel will sport the symbolic pink ribbon on their uniform, along with pink wrist bands to further demonstrate their support. Commemorative base jewels and dugout lineup cards will also be pink.

Barton brings superb glove to the bigs

OAK@CLE: Barton singles home go-ahead run in the 10th

CLEVELAND -- To replace injured outfielder Josh Reddick, the A's on Wednesday selected Daric Barton from Triple-A Sacramento. Barton started at first base and hit seventh on Wednesday night against the Indians.

Barton, who has not appeared for Oakland in 2013, has played in 468 games for the club across each of the past six seasons. In that time he has hit .249 with 27 home runs and 163 RBIs while proving himself as a reliable defender. He also drew 272 walks, which helped give him a .360 on-base percentage.

"Like most of the guys we bring up over the course of the season, he's having a good year," manager Bob Melvin said. "[Barton is] another good defender, an on-base guy, kind of all about what we've been doing here this year, and swinging the ball well on top of it."

Melvin said that Barton will primarily play first base and appear against right-handed pitchers, allowing Brandon Moss to move to the outfield, which has been affected by injuries. Against lefties, look for Nate Freiman to play first.

In Sacramento this season, Barton got on base at an impressive .422 clip. In 29 games he batted .287 with three home runs and 21 RBIs. He also added 24 walks and 16 strikeouts.

"I've heard a lot of [garbage] over the last two years about how I don't swing enough and how I walk too much," Barton said. "But if I'm on base 40 percent of the time, I'm OK with that, whether it be walks, hits, whatever it may be."

Barton has talked a lot about maintaining a positive mind-set and ignoring all the negative things people might write or say about him. Although such noise can affect a player in the batter's box, Barton said it should never inhibit a player's defensive efforts.

In the field is probably where Barton excels most, as he has a .992 career fielding percentage. Melvin praised Barton's glove work, saying that he is as good around the bag as just about anyone in the league.

"Over the last four years, I feel like I've been good defensively," Barton said. "I don't want to sound cocky or anything, but I'm really proud of how far I've come defensively and what kind of defensive player I am."

Added Melvin: "It always makes the infielders feel that much more secure when [if] you throw the ball across the diamond and you throw it in the dirt, you know there's a good chance he's going to pick it."

Injuries have Oakland using backup plans

LAA@OAK: Crisp pulls up running to first, leaves game

CLEVELAND -- The decision to bring up first baseman Daric Barton from Triple-A underscores just how severely Oakland has been affected by injuries this season.

In addition to Josh Reddick, who was placed on the 15-day disabled list retroactive to May 7, the group of injured outfielders includes Coco Crisp and Chris Young. Crisp has a strained left hamstring, and Young has a strained left quad.

"[Crisp is] moving around better. He's not feeling it when he walks around," manager Bob Melvin said. "I think he took a few swings off the tee. But I still feel like Chris Young has a better chance to come [back] before Coco does."

Melvin also mentioned a few injured pitchers. He said that Brett Anderson, who is dealing with a sprained right ankle, threw well in his bullpen session and is "feeling as good as he's felt here in a while."

Melvin also reaffirmed that he expects Jarrod Parker, who has a strained neck, to make his next start, scheduled for Saturday in Seattle.

"Very rarely is everybody going to be 100 percent," Melvin said. "Part of putting together the roster in the offseason by the front office was based on flexibility and being able to combat injuries.

"We never expected to have three of our outfielders on the [disabled list] at the same time, but a guy like Brandon Moss makes it a lot easier. He can go from first base and go to the outfield rather easily. We still have four good outfielders here right now. It's just a little different dynamic at first base."

On Wednesday against the Indians, Oakland started Seth Smith in left, Yoenis Céspedes in center and Moss in right.
