Sanchez was forced to exit Wednesday's game against Boston with a blister, Gregor Chisolm of MLB.com reports.

Analysis:

Sanchez's blister problems continue. He has already been on the disabled list three times this season with blister problems and has yet to build up a rhythm this season as well. It's unclear if this injury will result in a fourth disabled list trip quite yet, but given his struggles this year, it's understandable to be pessimistic after this news.
