An NBC cameraman has avoided upsetting Marc Leishman at the US PGA Tour's second playoffs event with a stunning flick of the leg.
The Australian golfer was struggling for his second shot on the par-five 18th hole at the Dell Championship, with little room to move in the weeds.
Leishman needed a birdie to finish second but it was always going to be a tough shot.
He shanked it badly to his right, leaving the cameraman to quickly move his leg out of the way.
"How about that dexterity? That is the move of the week!" said one commentator.
The ball landed near the greenside bunker and Leishman would end up with a bogey to finish third.
"I got things going just the way I wanted to on the front and then a bad tee shot on 10," said Leishman.
"There was some tough holes out there but certainly not 10 shots tougher than the front nine."
There was plenty of consolation to take from Leishman's week, however, as his performance tlifted him from 20th to seventh in the season-long points race standings.
It puts him right in contention for a big pay day, including the $US10 million bonus top prize, with two tournaments remaining in the playoffs.
The $US595,000 ($A745,000) pay cheque in Boston took Leishman's 2017 prizemoney passed the $US4 million ($A5 million) mark, a career best.
Thomas took his tally to five US tour victories for the season while was runner-up for the second consecutive playoffs event.
Thomas moved to No. 4 in the world and appears likely to pip Spieth for PGA Tour player of the year honours.
"We've just had a great year," Thomas said. "Obviously, there are two more events to finish it off,"
Spaniard John Rahm and Briton Paul Casey were a shot behind Leishman in a tie for fourth.
Jason Day had eight birdies but closed his round with three bogeys in five holes to shoot 66 and finish at six-under, and a tie for 25th.
The Australian world No.9 moved up one spot to 28th in the points standings.
After a one-week break, the top 70 players will tee it up in the penultimate event of the season before the an elite field of just 30 contest the end of season Tour Championship.
