Silvis, IL -- (Sports Network) - Kenny Perry two-putted for par on the first playoff hole Sunday and it was good enough to win the John Deere Classic after his two playoff opponents hit their second shots into the water in the extra session.

Perry bogeyed the par-four 18th at TPC Deere Run to close a round of one-under 70. That left him at 16-under-par 268, where he was joined by Jay Williamson and Brad Adamonis.

"I struggled hard today, tough golf course," admitted Perry, who collected $756,000 for the win. "That northwest wind is brutal out here. I didn't have it, but you know what, I fought hard and made some key putts at the right time. Things are just going my way."

Adamonis also shot 70 in the final round, while Williamson posted a two-under 69 to get into the playoff.

In the playoff at No. 18, Adamonis tried to play a spectacular second shot from the right rough. However, his shot bounced left of the green and into the pond next to the putting surface.

Williamson was up next. From the middle of the fairway, he pulled his approach shot into the pond and basically gave Perry the title.

After watching his opponents find the water, Perry knocked his second shot 25 feet right of the pin.

Williamson pitched his fourth to 17 feet and Adamonis putted from nearly 100 feet to within eight feet of the hole.

Perry ended the suspense right there. His birdie putt stopped within two feet and he kicked that in for par and his third win this season and 12th of his career.

Earlier this year, Perry lost a playoff at the TPC Sugarloaf to Ryuji Imada after his second shot to the par-five playoff hole hit a tree and ran across the green and into the water fronting the putting surface.

"The second shot is the one with all the trouble and it is kind of ironic that they both put it in the water. It kind of came back to me," Perry said of the playoff at the AT&T Classic.

Afterwards, he reiterated his stance that he will play the U.S. Bank Championship in Milwaukee instead of the British Open next week.

"I'm going to Rockford tomorrow to play in the pro-am and then I'll drive from there to Milwaukee on Monday night and play there next week," Perry stated.

Perry committed to that event earlier in the year when his goal was to make the U.S. Ryder Cup team. With this win, he is a lock to make that squad now.

Williamson does get one big perk despite the loss. Being the highest finisher not already qualified for the British Open, Williamson qualified and will head to Royal Birkdale as the final player to qualify for the season's third major.

Charlie Wi closed with a two-under 69 to share fourth place at minus-15. He ended alongside Eric Axley (71) and Will MacKenzie (70).

Adamonis birdied the first to take the lead at 16-under. However, he fell one back with bogeys on three and four. A 16-foot birdie putt on six moved him back to minus-15. At that point, Adamonis was tied with Perry and Wi.

Wi had birdied the first two to get there, but played the remaining 16 holes at even par, with 14 pars, one birdie and one bogey.

Perry rebounded from a bogey on the third to birdie the par-four sixth to get to minus-15, where he was again tied for the lead with Adamonis.

However, Adamonis came right back with a 13-foot birdie putt on seven to regain the lead at 16-under. He parred six straight from there and fell out of the lead during that span.

Perry grabbed a share of lead at the 10th with a nine-foot birdie putt. He birdied the short par-four 14th to move into the lead at 17-under.

Adamonis bogeyed the same hole to fall two back. He recovered that lost stroke with a birdie at the 17th.

Meanwhile, Williamson treaded water for the first half of his round. He was even-par with three birdies and three bogeys through 13 holes.

He moved to 15-under with a birdie on the 14th. Williamson then birdied the 17th to get within one of the lead.

Perry stepped to the 18th tee one shot clear of Adamonis and his playing partner, Williamson. Perry missed the green right and ran his chip off the left side of the green.

The 47-year-old chunked that chip, but saved bogey from seven feet to fall into a three-way tie for the lead.

"I kind of gave it away on the last hole and then I got it right back, they gave it right back to me," said Perry.

Williamson missed a 21-footer for birdie and the win, but tapped in for par to force the extra session.

Adamonis, who was in the final pairing, watched all of that transpire. He knocked his approach to 17 feet and had that for the win. However, his birdie putt came up well short and he tapped in for par to get into the playoff.

Chad Campbell carded four rounds in the 60s, including a final-round 69, to end alone in seventh at 14-under-par 270. Kevin Sutherland closed with a three-under 68 to finish one further back at minus-13.

Woody Austin, J.P. Hayes and Jeff Gove shared ninth at 12-under-par 272.
