Injury Updates

1B Vladimir Guerrero Jr, Toronto Blue Jays

Vladimir Guerrero Jr. is out of the starting lineup today against the Nationals after leaving last night's game with right hamstring tightness.Vladdy will "probably" be available to pinch-hit if needed, John Schneider announced. pic.twitter.com/Di7pddFZQP— Sportsnet (@Sportsnet) July 29, 2026Guerrero exited last night's game with right hamstring tightness. This could be nothing, but it could also be something. He will not be in the Jays' starting lineup tonight, so be sure to adjust your lineups. Beyond that, he could be in line to land on the 10-day IL, or he could pinch hit as soon as tonight's game. We will be monitoring this situation closely for fantasy baseball owners.
