Pro golfer Kevin Na wins fierce debate with caddie

Kevin Na was the first round leader at the Fort Worth Invitational thanks to a birdie on No. 9 at Colonial.

But it was what happened that led up to that birdie that's way more noteworthy.

Cameras and mics caught Na arguing about his second shot with his caddie Kenny Harms, in which Harms warns Na about where he's hitting his shot and the club he's selected.

"I'm going with it," Na says definitively.

Watch what happens after that shot:

Na ended up getting relief from the stands … and holed out the next shot for birdie.

"I told you!" Na said. And that's why the golfer always trumps the caddie in an on-course argument.
