What happened: Vladimir Guerrero Jr. was removed from Sunday's game with left lower back tightness. He was lifted following the top of the fourth inning.
Why it matters: Manager John Schneider said the first baseman aggravated the issue a few games ago while making a stretch. The injury comes as Toronto fights to stay in the American League wild-card race entering the final week of the season.
By the numbers: Guerrero was 1-for-2 with a single prior to his exit.
What to watch: The team decided to be cautious, but Schneider expressed hope Guerrero would be available for their next game.
