Neither player realized the error until they reached the green. The penalty for playing the wrong ball is two shots, so the players had to return to the spot where they hit the incorrect golf balls and play from the correct spot.

Rules official Mark Dusbabek said Davis played Zalatoris's ball and vice versa. Therefore, both players had to correct the mistake.

A mix-up between Australian Cameron Davis and American Will Zalatoris in the final round of The Sentry on Sunday led to both golfers walking away from the tournament with significantly reduced prize cheques.
