Like his Dominican compatriot Melky Cabrera, who also plays on the west coast and tested positive for testosterone and was suspended for 50 games by MLB, Bartolo Colon had recently been playing better than we expected him to. Colon, who pitched for the Yankees last year and Oakland this year, had a 111 ERA+ in 50 starts. He did that after missing all of the 2010 season and going AWOL during parts of the 2008 and 2009 seasons.
But unlike Cabrera, who slimmed down before improving his play, Colon was fat, and he stayed fat. He may have even gotten fatter, because doctors moved fat and stem cells from his butt into his arm last year, and more fat could have replaced the transported fat.
