Hamels was scratched from Monday's scheduled start against the Yankees with left groin soreness, Evan Grant of The Dallas Morning News reports.
Hamels missed a start last August due to a similar ailment, but the Rangers don't seem to be overly worried by this latest occurrence. The left-hander isn't expected to miss more than one turn in the rotation, so while he'll miss out on a two-start week, he should be lined up to take the bump during the Rangers' weekend series with the Angels. It's unclear who will replace Hamels on the mound Monday.
