Bronchial ailment keeps Teixeira out of lineup

NEW YORK -- Believing they have exhausted all available treatment options to this point, the Yankees are hopeful that a weekend of rest will be able to cure what ails Mark Teixeira.

The Yankees' first baseman has been battling a bronchial ailment since the club's Welcome Home Dinner in early April. He was out of the lineup for a second consecutive day on Saturday and could sit again on Sunday.

"It's not easy, but you have to sometimes take care of yourself and try to get better because it's a long season," said Teixeira, whose voice is now hoarse from extended coughing fits. "I want to make sure that I'm good for the long run."

Yankees manager Joe Girardi told Teixeira after Thursday's game in Toronto that he was thinking about having the switch-hitter on the bench for New York's series against the Reds.

Teixeira initially resisted, but Nick Swisher started at first base in Teixeira's place on Friday and Saturday. Eric Chavez could start at first base on Sunday, with Swisher returning to right field.

"Tex is a ballplayer and wants to play every day," Girardi said. "But I just said, 'You know what, Tex? Watching what you're going through, I just don't think a day is enough. Let's try something else.'

"And if we can't get rid of it with two or three days off, we'll know that the rest isn't necessarily going to help it, and we'll have to find some other way."

The Yankees have sent Teixeira to a number of specialists for treatment, and while the administered medication has succeeded in keeping Teixeira's ailment from getting worse, his condition has also not improved markedly.

"We've tried everything," Teixeira said. "That's why rest is like the last effort here. I've taken more medicine than I'd like to. I think we're done with that option. Rest is kind of the final straw here for us."

Teixeira said that he watched Friday's game from the bench and planned to do so again on Saturday, and he added that he did not expect to be available to pinch-hit. Girardi said that he preferred to have Teixeira report to Yankee Stadium rather than having him stay at home.

"You could do that, but you do have emergencies when you might need him," Girardi said. "And sometimes -- to put this in a nice way -- when you have young kids, you get more rest at the ballpark."

Robertson still bothered by strained oblique

NEW YORK -- Yankees reliever David Robertson is still feeling some discomfort in his strained left oblique, manager Joe Girardi said Saturday.

The Yankees planned to give Robertson 10 days off without throwing after an MRI taken on Tuesday in New York revealed the strain, but they are hopeful he could return in the minimum 15 days from the disabled list.

"He would feel it a little bit when he would cough," Girardi said. "We'll wait until Day 10 and then we'll make a decision if he's ready."

Bombers bits

• Yankees outfielder Brett Gardner (right elbow strain) was to be evaluated on Saturday to determine if he is ready to resume swinging a bat. Gardner has not played in a Major League game since April 17.

 • With Andy Pettitte winning Friday's game and Raul Ibanez homering, it marked the first time that an age 39 or older starting pitcher earned a win in a game when a teammate of that age homered since Aug. 18, 2008, when the Tigers' Kenny Rogers and Gary Sheffield combined to help Detroit beat the Rangers, according to the Elias Sports Bureau.

 • On this date in 1928, six-time All-Star Gil McDougald was born. McDougald batted .276 in 1,336 games for the Yankees from 1951-60, winning five World Series rings while appearing in eight total Fall Classics.
