Fans at the ballpark can keep foul balls, but for the most part, sports equipment stays in the field of play until the contest is over. That's not to say players don't hand out broken bats, batting gloves, basketball shoes -- like the ones Bubba Watson got from Kevin Durant -- after the fact.
And we've seen professional golfers hand out items during a round. Rory McIlroy made this kid's day by giving him a golf ball. And Phil Mickelson is known for giving signed golf gloves to spectators he may have hit with an errant shot.
But an unbroken driver? In the middle of a round? That's a new one.
But Danny Lee apparently got so fed up with his driver during Sunday's final round of the Travelers Championship that he handed it to a young fan and walked away.
Check out the surprised look on everyone's faces afterward:
It was definitely and up-and-down day for Lee, who finished with four birdies and five bogeys for a 1-over 71. And no, Lee wasn't allowed to replace the club, not that it seemed to matter in the end.
