Smoke signals

• Pitching prospect Trevor Bauer turned in an unusual line in his start for Triple-A Columbus on Tuesday. The 22-year-old right-hander held Charlotte hitless over 6 2/3 innings but also finished with two runs allowed, four walks, four hit batsmen, seven strikeouts and one wild pitch.

"He's still developing," manager Terry Francona said of the wild performance. "I think that's part of any 22-year-old pitcher. He's still developing. I don't think anybody's a finished product that young."

Cleveland will need a starter for one of the games of Monday's doubleheader against the Yankees. Bauer, who served as a spot starter on April 6 and May 1, is a possibility, but Francona sidestepped questions about any potential promotions.

• Francona indicated that rehabbing starter Brett Myers (on the 15-day disabled list since April 20 with an injured right elbow) is scheduled to throw off a mound in a bullpen session on Friday, when the team is in Detroit. Myers will throw to catcher Lou Marson, who is on the 15-day DL with soreness in his right shoulder.

• Entering Wednesday, the Indians had hit at a .286 clip over their past 20 games, raising their season average from .241 to .271, which ranks third in the Majors behind the Rockies and Tigers. The Tribe also ranks in the top three in the Majors in home runs (tied for first, with 44), slugging percentage (first, .470), extra-base hits (third, 113) and total bases (third, 490).

• Setup man Vinnie Pestano, who was placed on the 15-day DL on Monday with tendinitis in his right elbow, will likely take at least two more days off before resuming a throwing program, according to Francona. Pestano is eligible to be activated on May 16.

• The Indians eked out a 1-0 victory over the A's on Tuesday behind one unearned run. It marked the first time since July 3, 1968 (when Luis Tiant struck out 19 in a 10-inning victory over Minnesota), that Cleveland won a 1-0 contest without an earned run and was also outhit by its opponent.
