As with most golf tournaments, picking a definitive winner prior to the PGA Tour Championship was difficult. Despite Patrick Cantlay holding the top spot in the leaderboard for most of the season-ending contest, the title was still up for grabs on Sunday.

In the end, Cantlay held on to win the trophy by one stroke over Jon Rahm after carding a 1-under 69 in the final round. While the finish was thrilling, perhaps this year's PGA Tour Championship would be most remembered for a fan stealing the spotlight. Quite literally.

On Saturday, Bryson DeChambeau hit a long par-5 on the 18th hole. A fan, however, casually decided to pick up the ball and walked away with it! Like a thief in the daylight. The fan probably thought “Hey, a ball! I need it.” That's a rule, right? DeChambeau kept looking for his ball but to no avail. It's because he was looking at the wrong places. He should've looked into the obvious ones. Like a fan's pocket maybe.

Quite fortunately for DeChambeau, officials of the PGA Tour Championship allowed him to have a free drop, which he converted into a birdie. This helped him stay in contention with Cantlay and Rahm, but it sure made for an oddball moment.

There's stealing in basketball, baseball, football, and other sports. But not in golf. Unless apparently, you're playing in the PGA Tour Championship.

DeChambeau hasn't had much luck recently, also losing to Cantlay in the BMW Championship last week. Someone keeps, um, stealing his thunder.
