Perez to miss next start; Tepesch on the way

ARLIINGTON -- Martin Perez experienced discomfort in his left elbow after his third straight subpar start Saturday and will miss at least one start. He was previously slated to make his next start Friday against the Blue Jays.

Right-hander Nick Tepesch was scratched from his start for Triple-A Round Rock on Sunday and will start for the Rangers in Wednesday's series finale against the Astros. Tepesch is 6-1 with a 1.58 ERA for Round Rock this year, going 4-0 with a 0.35 ERA in his last four starts. He went 4-6 with a 4.84 ERA in 19 apperances, including 17 starts, as a rookie with the Rangers last season.

Yu Darvish, who was originally scheduled to start Wednesday, will now take the mound Friday. Darvish threw 126 pitches in Friday's win over the Red Sox, when he took a perfect game into the seventh inning and lost a no-hitter with two outs in the ninth inning for the second time in his career. But the decision to move him back to Friday was primarily because Perez was scratched from his next start.

Perez has followed three stellar starts with three subpar performances, going 0-3 with a 12.83 ERA in his last three outings after winning his previous three starts, tossing a collective 26 scoreless innings during a stretch that included back-to-back complete-game shutouts. Perez allowed six runs on nine hits over a season-low 3 2/3 innings of Saturday's 8-3 loss to the Red Sox.

"You can see the wheels turning a little faster than it did in the beginning," Washington said. "He's got to slow it back down. Once he slows it back down and starts to believe in his stuff, he'll get back to where he needs to be."

With the strange string of outings, Perez became only the second player in the modern era to follow up three straight scoreless starts by surrendering at least as many runs as innings pitched in each of his next three starts. His next start is scheduled for Friday against the Blue Jays.

"When you're dealing with youth, you're dealing with guys that haven't had a lot of failure," Washington continued. "If you're not patient, you can destroy them more. So you've got to be patient. We believe in him. We've got to get him back to believing in himself."

Rangers honor breast cancer survivor

ARLINGTON -- Fortunately for Sheila Taylor, her favorite color is pink.

Taylor, who has twice defeated breast cancer, was selected as the winner of the Rangers' Honorary Bat Girl contest and honored in a pregame ceremony Sunday. She visited with players before the Rangers' series finale against the Red Sox, including Geovany Soto, Leonys Martin and Michael Choice. Also part of the package were two tickets to Sunday's game and pink MLB merchandise.

"I feel like I stand for all the women in Texas who are battling this disease and hope I can do something to promote breast cancer awareness as the Rangers' Honorary Bat Girl," said Taylor. "It's a wonderful honor, especially on a day like Mother's Day. I tease my family that they got off easy because they didn't have to do much today. But it's wonderful to have something like this when you've been in the battle of your life two times."

Accompanying Taylor were her husband, Nate, 4-year-old daughter McKenzie and good friend, Devin. Taylor, whose mother-in-law died of breast cancer at the age of 46, serves on the Board of Directors for The Bridge Breast Network, an organization that provides medical care to women with breast cancer but no health insurance.

"Seeing everybody embrace this with the pink bats, the ribbons and pink everywhere," Taylor said. "It lets us know we're not alone in this battle."

Andrus comfortable again in No. 2 spot

ARLINGTON -- A week after being moved down to the ninth spot in the lineup, Elvis Andrus looks very comfortable batting second again.

Andrus hit ninth in last Sunday's win over the Dodgers and did not return to the second spot in the lineup until Friday's win over the Red Sox. In two games since returning to hitting second, which he's done in 32 of 37 games this year, Andrus is 6-for-9 with three runs, two doubles and one RBI.

"I feel a lot better right now," Andrus said. "It doesn't really matter for me. At any spot in the lineup, you're still going to have an opportunity and you're still going to have to execute."

Andrus took a seven-game hit streak into Sunday's game against the Red Sox and his batting average is up to .255 -- 28 points higher than it was before he started hitting second again. He had multiple hits in both games since after having no multi-hit efforts in the 21 previous contests.

"I'm happy to see him starting to get back to Elvis," Rangers manager Ron Washington said. "When I took him out of the second hole and at the bottom of the lineup, he took a deep breath. He was really rigid. When I put him down there, he loosened up."

Chirinos solid behind plate so far

ARLINGTON -- For the second time this season, Robinson Chirinos threw out a pair of attempted basestealers in Saturday's loss against the Red Sox.

Chirinos caught David Ross stealing in the second inning of that game and caught Pedroia stealing in the fifth. He has now thrown out 41.2 percent (7-of-17) attempted basestealers while Rangers pitchers have gone 12-9 and posted a 3.74 ERA in the 21 games Chirinos has played. They are 7-9 with a 5.67 ERA in the 16 games he hasn't played.

Chirinos has been working with Rangers first-base coach Bengie Molina, a former catcher, on his craft.

"You see a transformation in him becoming a pretty good catcher," Rangers manager Ron Washington said. "He's got a quick release. I'm surprised at the strength. But then I never had a chance to see it. So maybe it was there, I just never had a chance to see it."

Worth noting

• Right-hander Scott Baker and infielder Josh Wilson cleared waivers Sunday. Baker accepted his assignment to Triple-A Round Rock while the Rangers are awaiting a decision from Wilson, who has the option to turn down the assignment.

• Justin Germano made his Rangers debut Saturday, increasing the number of players used by the Rangers this year to 37 -- tied with the Angels for the most in the Majors.

• Rafael Palmeiro hit his 500th career home run 11 years ago today, a three-run shot in the seventh inning of a 17-10 win over the Indians.

• The Rangers are 24-19 all-time on Mother's Day and have won four of their last five Mother's Day games.
