If a runner correctly touches a base that was missed (either in advancing or returning), the last time he was by the base, that last touch corrects any previous baserunning infraction.

• A. True.
• B. False.
• C. It depends on the umpire's judgment.
• D. Only if no other baserunning infractions occurred.

Answer: (A)

Missing a base is a baserunning infraction, but that infraction can be cured by the runner later touching the missed base. The touch that occurs when he’s last by that base is the one that counts and retroactively corrects the earlier miss, so there’s no out for that missed base simply because the runner later touched it, provided there isn’t a timely appeal or other rule intervention that would change the call. That’s why this statement is true.
