The Toronto Blue Jays announced that pitcher Marco Estrada left his Triple-A rehab start in Buffalo on Tuesday with a blister on his right middle finger.

The Blue Jays placed Estrada on the 10-day disabled list on July 13. The starter left the mound after recording just one out in the first inning against the Atlanta Braves on July 10, and an MRI the next day revealed a left glute strain.

Estrada is 4-7 on the season with a 4.72 ERA.
