CINCINNATI -- For the first time this season, the A's are going forward secure in the knowledge they won't lose starting pitcher Bartolo Colon to a suspension over the Biogenesis performance-enhancing drug furor.

The players the Major League Baseball investigators targeted were announced Monday, and Colon, who served a suspension a year ago -- although few had ever heard of the Biogenesis firm at that time -- was not made to serve a second penalty for his involvement.

The A's had thought all along that he would not be penalized a second time, but the club wasn't absolutely sure until Monday's list of players was made public.

"I'm glad I was right about that one," manager Bob Melvin said. "It would have been quite a loss for us."

Colon, who pitches in Wednesday's finale, has a 14-3 record and 2.50 ERA, which leaves him tied for second in baseball in wins and ranked third in the American League in ERA.

Asked about the impact on the A.L. West race with second-place Texas losing home run and RBI leader in Nelson Cruz (27 and 76) to a 50-game suspension, Melvin took the high road.

"They have a good lineup as it is," he said. "They have a good rotation that's going to get stronger and a pretty good bullpen. One guy in the lineup shouldn't change our feelings about them.''

  • Melvin suggested that a day off may be in the cards at some point for third baseman Josh Donaldson, but with the A's in the middle of three days off in an eight-game span, a rest will probably wait until the homestand that begins Tuesday when the Houston Astros come to town.

    The manager is feeling more comfortable with Alberto Callaspo in the fold, because for the first time this season, Oakland has a player Melvin knows can play third. Callaspo was the Angels' third baseman before the A's picked him up to play mostly second base.

    Is Donaldson tired?

    "He doesn't look it to me," Melvin said. "Other teams have (players who play every day), too. He's one of that group. And he wants to do it, too."

  • MLB Network is televising Wednesday's game, which starts at 9:35 a.m. in the Bay Area.
