CROMWELL, Conn —
After a 17-foot birdie putt on the next hole, he made a 45-footer on the 13th hole, a shot that looked as though it might go past the hole to the right, before falling in.
He battled Watson for the lead down the back nine, until the former Masters champion found trouble on the 16th.
Watson put his drive into the water and put his next shot over the green.
He finished two strokes back in fourth place.
"The wind affected the first shot, and the wind didn't affect the next shot," Watson said. "I flew it three feet past the hole, which you can't do right now because the greens are so firm."
Duke looked as though he had the tournament sewn up after saving par on 18, despite a tee shot that went well right and onto a hill, and a second shot that went just over the green. He used a putter to put the ball within 2 feet, then sank the putt as the crowd roared for what they thought was a winning shot.
It looked even more secure when Stroud's second shot hit near the stick, but then rolled well off the green. That just set up the dramatic chip shot.
Stroud hit his tee shot over the cart path and 94 yards from the hole on the first playoff hole, while Duke's first shot jumped out of a fairway bunker and into the rough.
Duke bounced his second shot onto the green. Stroud's went into a greenside bunker.
Stroud chipped to 8 feet but had to watch as Green almost sank a long putt that would have ended it.
The two both struck the ball well on the second playoff hole, but Stroud missed a 25-foot birdie putt, and Duke made his short putt.
