NAPBL Umpire Manual Ruling 3.12, page 27 DEFENSE MUST APPEAL ORIGINAL BASE AFTER CATCH

When a runner misses a base and a fielder holds the ball on the missed base, or on the base originally occupied by the runner if a fly ball is caught, and appeals for the umpires decision, the runner is out when the umpire sustains the appeal.


Play: Runner on first, batter hits the ball far into the outfield and runner races for third. Catch is made, and outfielder throws ball to shortstop who steps on second base asking umpire to rule an out.

Ruling: This is improper play by the shortstop, as runner may be called out only by being tagged or first base being touched before the runner reaches first base.

This is the Minor League interpretation, but I have a hard time believing it would be different in MLB.
