Kenny Perry parred the first hole of a playoff to edge American compatriots Brad Adamonis and Jay Williamson to win the $A4.34 million PGA John Deere Classic.
Perry won his third title in his past five starts by firing a final round one-under 70 to join the three-way sudden death playoff.
Adamonis also shot 70 while Williamson had a two-under 69 at the Deere Run course. All three players finished 72 holes at 16-under 268.
David Lutterus was the best placed Australian finishing seven shots off the pace after a final round 69 while compatriot Aaron Baddeley (73) finished a further stroke back.
Perry's productive streak started with a win at The Memorial and he also won his last start, the Buick Open.
After Adamonis and Williamson found the water on 18 in the playoff, Perry played it safe.
Perry could have wrapped up the victory without going into a playoff, but he bogeyed the 18th after needing three shots from 30 feet from the hole.
The bogey opened the door for Adamonis, who had a 20-foot birdie putt on 18 for the win, but he left it well short and then hit his drive to start the playoff into the trees down the right side of the fairway.
Williamson was in the middle of the fairway but pulled his approach into the water and Perry took two putts from 25 feet to wrap up the win.
Perry started the day in a tie for the lead with Adamonis and Eric Axley, who came up short on a 26-foot birdie putt at 18 that would have put him in the playoff.
