BALTIMORE -- Tammy Kestler has been selected as the Orioles' winner of the Honorary Bat Girl Contest, which recognizes fans from all 30 teams whose lives have been affected by breast cancer. The contest is a part of Major League Baseball's "Going to Bat Against Breast Cancer" initiative, which aims to spread awareness about the deadly disease and honor those who have been affected.

In addition to being recognized on the field during the O's game against the Rays on Sunday, Kestler will participate in pregame activities, receive pink MLB merchandise and be provided with two tickets to the game.

Hundreds of players across the Majors will use pink bats stamped with the breast cancer awareness logo on Sunday, with others wearing pink wristbands or the symbolic pink ribbon on their uniform. The bats will be auctioned off following the game, with proceeds going to cancer research.

Kestler was selected by a fan vote and a guest-judging panel of MLB players, media personalities and other celebrities. This is the fourth year in a row that MLB has held the Honorary Bat Girl Contest.

Pomeranz's debut a bright spot in O's loss

BALTIMORE -- If there was a bright spot to be found in Monday's 14-3 loss to the Texas Rangers, it was the performance of Orioles reliever Stu Pomeranz, who fired three scoreless innings in his Major League debut.

The 27-year-old Pomeranz, whose contract was purchased from Triple-A Norfolk before the game, entered in the sixth inning in place of starter Brian Matusz and used a fastball that topped out at 95 mph to hold a lethal Rangers lineup in check.

"I liked the way he handled himself," Orioles manager Buck Showalter said of Pomeranz, who signed with the organization in February and turned heads -- despite not receiving an official invite -- in big league camp this spring.

"He had a lot of mound presence and attacked the strike zone. He hides it well, but you know there had to be a lot of emotion flowing around out there. I was real proud of him. That was probably the highlight for us."

Pomeranz, the older brother of Rockies left-hander Drew Pomeranz, held the Rangers to three hits and a walk, picking up two strikeouts in his 48-pitch outing. Asked what was going through his mind when he ran out of the dugout and took the mound, Pomeranz -- who admitted the nervous energy faded away -- said he didn't want to take in the moment.

"I didn't want to realize what I was doing until after it was done," said Pomeranz who was pitching in Double-A Bowie two weeks ago. "Obviously, it's a big deal. It's my first outing in the big leagues."

Signed on Feb. 2 after impressing the organization during a tryout and securing a spot in minicamp, Pomeranz was frequently called over from the Minor League side this spring, and he's continued to have success at every level so far.

"It's good to see a guy carry over exactly what he's been doing," Showalter said. "He was in camp with us for 27, 28 days, and I think being around that environment and being around the guys made it a pretty easy transition. He knew everybody. He's one of those guys who wasn't in big league camp but was in big league camp."

Davis' remarkable relief has Baltimore abuzz

BALTIMORE -- A day after infielder Chris Davis' improbable performance as the Orioles' winning pitcher in a 9-6 win over the Red Sox that took 17 innings, the 25-year-old's first career outing on the mound -- which Davis joked was hopefully his last -- remained a hot topic in Baltimore on Monday afternoon.

Given the quick turnaround following Sunday's contest, which lasted more than six hours, Orioles manager Buck Showalter admitted he hadn't had much time to reflect on the bizarre victory, which marked the first time since 1968 that an American League position player recorded a win. But Showalter, a self-described media-guide junkie, did reiterate the importance knowing that Davis knew his way around a mound before telling the slugger to head out to the bullpen to warm up.

"They all think they can pitch until you get out there," Showalter said. "I was always the designated guy who had to pitch when the team was getting blown out in Triple-A with Johnny Oates. Until you remove that screen and see how close that batter is and how close that wall is, it's a whole different gig. Chris has some experience with it. The other guy was Nicky [Markakis]. I waited as long as I could before I had to break it to Chris. It's not something you want a guy thinking about for a long time. I just basically said, 'Get your glove, go down and warm up. You're in next inning, unless we score.'"

So Davis took the mound to face the bottom of Boston's order in the 16th inning, with catcher Matt Wieters greeting Davis for a quick mound meeting. Wieters' words of advice?

"Don't blow it out -- just throw strikes," Wieters said. "That was pretty much all I said to him. That's probably the easiest 89-91 [mph] I've ever seen. He came out and threw strikes and had a little movement on it. That was pretty impressive."

Worth noting

• Five Orioles -- Endy Chavez, Davis, Tommy Hunter, Darren O'Day and Pedro Strop -- who were members of the Rangers in 2011 received their American League championship rings in a ceremony before Monday's game. Injured Baltimore catcher Taylor Teagarden was also with Texas in 2011, but he will receive his ring at a later time.

• The Orioles recognized Showalter for his 1,000th career win with a ceremony prior to Monday's game. Showalter became the 58th manager to win 1,000 games when the O's beat the Yankees, 7-1, last Tuesday.

• Miguel Tejada passed his physical at the O's extended spring facility in Sarasota, Fla., on Monday and will sign a contract to rejoin the organization for a third time on Tuesday. Tejada will work out in Florida for the foreseeable future, and according to executive vice president of baseball operations Dan Duquette, the infielder will be put on a program there to get back in baseball shape.

The 37-year-old Tejada last played with the Orioles in 2010, spending time with the Padres and Giants after that.

• Former O's infielder Brandon Snyder started at third base for Texas and batted eighth on Monday, driving in two runs with a second-inning single before hitting a three-run homer in the sixth. With the start, Snyder has appeared in 12 games for Texas this season after playing in 16 games with the Orioles in the 2010 and '11 seasons.

• Class A Delmarva's Dylan Bundy -- the No. 9 prospect in baseball, according to MLB.com -- was named the organization's Pitcher of the Month for April after opening his professional career with 17 scoreless innings.

Bundy entered Monday's start having given up just one hit and two walks, with 25 strikeouts, but he surrendered his first professional run -- an unearned run -- to Charleston on Monday. The right-hander struck out eight in three one-hit innings.

The organization's Player of the Month was Class A Advanced outfielder Ronnie Welty, who has posted a .415 batting average with three home runs and 17 RBIs in 13 games.
