The Blue Jays activated Jose Reyes for Wednesday's game against the Rays.
Reyes had been sidelined since mid-April with a left ankle injury.
To make room for Reyes, Toronto optioned Munenori Kawasaki to Triple-A Buffalo.
"It's tough," John Gibbons said. "You feel for the kid -- he did a tremendous job for us. But he'll be back."
Filling in for Reyes, Kawasaki hit .225/.337/.325 with seven stolen bases.
