Well, Melky Cabrera might now have some company. Jon Heyman is reporting that Bartolo Colon has failed a drug test and is subject to a 50 game suspension by MLB, which would end his season and make him ineligible for most of the playoffs.

Colon has been fantastic for the A’s this season at age 39, but his career revival was subject to some skepticism surrounding the injections of platelet rich plasma that he received in 2011, which raised questions about what kinds of treatments are performance enhancing in a viable way and which ones should be illegal. Colon was the poster child for the positive effects of PRP, and it seems unlikely that promoters of the treatment will continue to lean on him as evidence of its success.

For the A’s, this is certainly a blow, but the arrival of Brett Anderson from the disabled list now looks like incredibly valuable. Anderson might not be able to pitch at the same level that Colon did, but he should be able to replace most of that production, and help keep Oakland in the pennant race.

For Colon, my guess is that this will be the end of the line. He had trouble finding work last winter, and now heading into his age 40 season and coming off a PED suspension, I don’t imagine too many teams will be lining up to give him another shot.
