So, Uh, Bartolo Colon Tested Positive For Testosterone ...

Via Jon Heyman:

Veteran A's pitcher Bartolo Colon failed an MLB drug test and is subject to a 50-game suspension, CBSSports.com has learned.

Colon resurrected his career after a controversial stem-cell treatement. He is 10-9 with a 3.43 ERA for the A's this year after going 8-10 with a 4.00 ERA with the Yankees last year.

Colon's suspension comes on the heels of the 50-game suspension for Giants outfielder Melky Cabrera.

This news hits a little bit closer to home for the Rangers fan base than the Melky situation, obviously, as the Athletics are running in second place (albeit five games back) and still have an outside shot at the division title, as well as a more realistic shot at a wild-card spot. Colon's been humming along with a ~2.5 WAR this season over 150-plus innings this season, so, as a practical matter, this isn't a crippling blow to their post-season hopes ... but it certainly doesn't help, particularly when you take notice of the fact that Colon had thrown up a 2.55 ERA with good peripherals since the end of May.

Also, Yahoo! Sports' Tim Brown notes on Twitter that Colon actually tested positive for testosterone. Other reports are surfacing indicating that the suspension is already official. And so, with baseball's P.R. department still reeling from the fallout from the Melky imbroglio, they now have this to deal with.
