Bubba Watson sank an 18-foot birdie putt on the last hole on Tuesday to give a US trio representing the PGA Tour a triumph over the Champions and LPGA tours in the Three-Tour Challenge.
The closing birdie gave Watson, Boo Weekley and Dustin Johnson a combined 14-under par score in the best-ball showdown at Rio Secco Golf Club in which each team could drop the score of one player on every hole.
"Having a chance to make that putt is something you dream about," Watson said. "When you actually make it, you don't know what to do."
The Americans rallied to shoot 11-under over the last 11 holes for a one-stroke victory over the 50-and-over Champions Tour lineup of Zimbabwe's Nick
Price, Germany's Bernhard Langer and American Kenny Perry.
The defending champion LPGA team of Norway's Suzann Pettersen and Americans Natalie Gulbis and Cristie Kerr finished third at 11-under.
PGA players were four down with seven holes remaining and two off the pace at the 17th tee. Johnson eagled the par-5 hole, sinking an eight-foot putt, and Watson birdied 17 to pull the PGA level with the Champions entering the 18th.
"I knew I needed to make something happen on 17," Johnson said.
Watson, who won his first PGA title this year, put his second shot from 150 yards to 18 feet and rolled in the winner.
Langer had a 12-foot birdie putt to force a playoff but it rolled left of the cup, giving the PGA the 500,000-dollar top prize in the made-for-television event.
The Champions side took 270,000 dollars while the LPGA players took 230,000 dollars.
Watson, Johnson and Perry shared low-individual honors at four-under par 68.
The PGA has eight victories in the event while LPGA and Champions players have each won six times.
