Reimold left the game in the top of the fourth inning when he appeared to injure himself running the bases. Reimold pulled up limping while advancing from second to third on Juan Francisco's groundout to the right side.
The Blue Jays called the injury a left calf strain, and Reimold is also day to day.
Reimold had walked to lead off the inning. After the injury, Darin Mastroianni replaced Reimold as a pinch-runner and remained in the game in right field.
The Blue Jays claimed Reimold off waivers from the Orioles on Sunday. The 30-year-old Reimold has dealt with multiple injuries over his career, and he has had surgeries on his neck and Achilles tendon.
