Injured ace Bartolo Colon was left off the Los Angeles Angels' roster for the AL Championship Series Tuesday and will not pitch against the Chicago White Sox. A 21-game winner during the regular season, Colon left his start Monday night against the New York Yankees in Game 5 of the playoffs after only 23 pitches because of inflammation in his right shoulder. He had been bothered by tightness in his back since early September, and was to be re-evaluated by team doctors on Tuesday before Game 1 of the ALCS. The right-hander was expected to have an MRI on Wednesday in Chicago. "You have to know Bartolo, he's a horse. This guy doesn't complain about anything. When he says something is bothering him, you know it's significant," Angels manager Mike Scioscia said.
