What happened: Aaron Boone said Trent Grisham has a hamstring strain. Boone said it is too soon to determine whether Grisham will return during the regular season, though that remains possible.
Why it matters: The uncertainty complicates New York's outfield planning for the stretch run. Any extended absence would reduce the Yankees' available options as the schedule winds down.
By the numbers: The Yankees lost 4-3, turning a 1-1 series tie into a 2-1 deficit.
What to watch: Watch for the Yankees to establish a recovery timeline and clarify Grisham's regular-season availability.
