Left-hander Watson pumped his left fist in celebration after his winning putt dropped into the cup before shaking hands with Simpson and then being embraced by his wife Angie.

“Somehow now I’ve got three,” a jubilant Watson told reporters after ending a breezy afternoon at the TPC Louisiana with his third PGA Tour title in 11 months.

“A year ago I was a good player who (had) never won, and now I’ve got three under my belt so it’s crazy. It’s something that I could never dream of.

“For me to get one was unbelievable. My career was complete. I’ve done it. Then for me to get another one just adds to my career. It’s something I’ve dreamed about doing.”

The pair had finished the 72 regulation holes on 15-under-par 273 after closing with matching three-under 69s, Watson having narrowly missed a birdie putt from nine feet at the par-five 18th.

Watson then sank a 12-foot birdie putt at the first extra hole to keep the playoff alive. Simpson recorded a two-putt birdie there, his second putt from just three feet.

Jason Dufner birdied the last for a best-of-the-day 66 to tie for third at 13-under, level with fellow American Tommy Gainey (69) and South Korea’s K.J. Choi (69).

British world No. 3 Luke Donald birdied four of the last six holes for a 69 to finish in a five-way tie for eighth, five strokes off the pace.

The final round was a two-horse race, though, between overnight leaders Simpson and Watson who duelled for supremacy with a sizzling display of shot-making in the first eight holes.

They each eagled the par-five second and were four-under for the day after just five holes.

The tournament appeared to turn decisively at the par-3 ninth where Watson found water with a wedge off the tee and double-bogeyed the hole to slip two strokes behind.

Simpson, who reached the turn in four-under 32, then forged three ahead with another birdie at the par-four 10th after an exquisite approach ended up within three feet of the pin.

However, Simpson stumbled with a bogey at the 12th and his lead was cut to one when world number 16 Watson knocked in a four-footer to birdie the 13th.

Simpson suffered a harsh blow at the par-four 15th where he was docked a one-stroke penalty when his ball fractionally moved in the wind after he had grounded his putter.

Facing a tap-in par putt from one foot, Simpson placed his putter roughly five inches behind the ball without taking a stance and immediately backed away as his ball oscillated.

After summoning PGA Tour rules official Gary Young to review the incident, he was penalized and ended up with a bogey five to drop back into a tie for the lead at 15-under.

“A little unfortunate what happened on 15,” said Simpson, who was bidding for his first PGA Tour victory. “I better limit my comments on that rule, because I think it’s such a bad rule.”

The next two holes were parred before Watson squandered an opportunity to seal victory in regulation with a birdie on 18.

“I hit some good shots coming in and gave myself a chance,” said the 25-year-old, ranked 98th in the world. “Unfortunately, I just came up a little bit short.

“It was fun being out there with Bubba. He’s a great friend and a great champion. I’m happy for him. He hit some great shots and great putts coming in.”
 
Hjorth wins Avnet LPGA Classic

In Mobile, Alabama, Maria Hjorth took advantage of Alexis Thompson’s collapse in a failed bid to become the youngest LPGA Tour winner, rallying to win the Avnet LPGA Classic for her fifth tour title.

The 37-year-old Swede shot her second straight 5-under 67 to finish at 10-under 278, two strokes ahead of Song-Hee Kim (71) on The Crossings course at the Robert Trent Jones Golf Trail’s Magnolia Grove complex.

The 16-year-old Thompson, tied for the lead with Kim entering the round, had a 78 to drop into a tie for 19th at 1 under. Na Yeon Choi (69) and Suzann Pettersen (70) finished three strokes back.
