What happened: Ronald Acuña Jr. left tonight's game with a left shin contusion. X-rays were negative and he is listed as day-to-day.

Why it matters: An absence from the starting outfield requires a lineup adjustment. The series between the Tampa Bay Rays and the New York Yankees is tied 1-1 ahead of a scheduled meeting at 0-0.

What to watch: His availability before first pitch of the next game is the next checkpoint.
