Jacob deGrom's return for the AL West-leading Texas Rangers has been pushed back until at least late June after the two-time National League Cy Young Award winner was transferred to the 60-day injured list Monday.

DeGrom hasn't pitched since April 28, when he exited early because of injury concerns for the second time in a span of three starts. He was placed on the 15-day IL the following day after an MRI showed inflammation in his right elbow.
