Bryson DeChambeau's odd moment came after sour interaction with fans at BMW Championship

DeChambeau was competing for a first-place finish at the Tour Championship and was on the 18th hole at East Lake when he hit a wild shot off the tee. He couldn’t find the ball and officials determined a fan picked up the ball and walked away with it. He was awarded a free drop.

DeChambeau made the green in two and finished with a birdie on the hole. He was the fifth player to hit the green on the 18th hole in two shots, according to the PGA Tour.

He finished the tournament Sunday in seventh place with a 13-under par. Patrick Cantlay came away with the victory, edging Jon Rahm by a stroke.

Last weekend, DeChambeau got into an incident with fans at the BMW Championship.

While walking toward the tunnel near the 18th hole at Caves Valley Golf Club, DeChambeau handed his hat to a young fan but just moments later another spectator shouted, "Great job, Brooksie," referencing DeChambeau’s longtime feud with Brooks Koepka.

"You know what? Get the f--- out!" DeChambeau yelled, via ESPN. DeChambeau reportedly "had rage in his eyes" but quickly diffused the situation after motioning for security to come over.
