The Blue Jays placed designated hitter Adam Lind on the disabled list with strained back.
The move was made retroactive to July 26. To fill Lind's roster spot, the Blue Jays recalled first baseman David Cooper from Triple-A Las Vegas.
Toronto currently has 12 players on the disabled list. Lind, who also played first base, was having a resurgent month after spending time in Las Vegas earlier this season to work through confidence issues at the plate.
