Valdez was recalled by the Blue Jays on Saturday, Ben Nicholson-Smith of Sportsnet reports.
The Blue Jays recently claimed Valdez after he was designated for assignment by the A's. He was touched up for three or more runs in three of his four outings with Oakland earlier in the season. He'll add some depth to the Blue Jays' bullpen, likely as a middle reliever with the capability to go multiple innings if needed.
