Tom Kim, Brian Campbell Each Hit Penalized for Wrong Ball

Tom Kim and Brian Campbell each took a two-stroke penalty during the second round of the Mexico Open at Vidanta Vallarta on Friday after the two PGA Tour players hit each other's golf ball out of the same greenside bunker.

What happened on the 9th hole?

The ninth was Kim and Campbell's final hole of the round after both started on the back nine. Each player arrived at 5-under for the round and 9-under for the tournament. Both tee shots found the left side of the fairway, and both approach shots landed in the same bunker to the right of the green. From the sand, Kim played Campbell's ball and Campbell played Kim's. Television cameras caught the two players and a rules official discussing the mix-up beside the bunker before each was assessed the penalty. Both players finished the hole with a double bogey.

What is the penalty for playing a wrong ball?

Rule 6.3c(1) of the Rules of Golf sets a general two-stroke penalty in stroke play for playing a wrong ball. The player must then correct the error by playing their own ball as it lies, or by taking relief under another applicable rule, and any strokes made with the wrong ball do not count toward the score. The rule becomes a disqualification only if a player fails to fix the mistake before making a stroke on the next hole or, on the final hole of a round, before returning their scorecard. Kim and Campbell each corrected the error in time.

You've got to pay close attention to what you're doing.

Golf Channel analyst Brendon de Jonge, calling the broadcast, said players sharing a bunker need to check whose ball is whose before swinging. Both Kim and Campbell continued play and remain in the field for the weekend at Vidanta Vallarta.
