I don't know about Vargas, but we know for a fact that Shane Smith is approaching a career high in innings not even halfway through the season, and his previous career high of innings was achieved over a 6 month period and not a 3 month one. Because of this it is tough to pick apart what is conditioning, what is the league figuring him out, or some combination of both. Obviously on the conditioning side of things, the Sox need to get more involved in picking their spots to give him shorter outings, longer breaks etc. It would be nice to let him continue on, but you really have to monitor his stuff his health to make sure that he isn't hurting himself to continue. Injuries increase with fatigue, and we need to make sure we don't let that happen into a more major injury.
