Manager Mike Scioscia announced today that Bartolo Colon will start Friday against the Chicago White Sox and that Ervin Santana will be dropped into the bullpen. If Santana were to make the playoff roster, it would be as a reliever anyway, so the Angels want to see if he can be an effective in that role. In essence, this looks like a three-week tryout to see if Santana can work his way onto the playoff roster. It already seems likely that Colon will not be a part of the postseason unless, of course, he is completely dominating in the three starts he would get before the end of the season.
