Vargas was placed on the 15-day DL on Saturday with a left flexor strain. Vargas had been pitching fairly well of late, tossing six scoreless innings and getting the win in his last outing against Minnesota. It is not clear how long Vargas will be out, but he will miss at least a few turns in the rotation. Brandon Finnegan was recalled from Triple-A to add bullpen depth in the short term and Joe Blanton will take his rotation spot.
