"It was after that stretch, obviously," Schneider said. "At this time of year, everyone is kind of grinding a little bit, and that just irritated his hammy. It's just tightness."

Vladimir Guerrero Jr. makes an incredible play by doing a split to record an out for the Blue Jays, but would be pinch hit for a couple innings later.

Guerrero is set to undergo an MRI on Tuesday, per Schneider, to determine the extent of the injury.
