BLANC, Mich. — Kenny Perry has picked the perfect time to play his best golf in two-plus decades on the PGA Tour.

Perry shot a 6-under 66 on Sunday to win the Buick Open by a stroke at 19 under, giving him two victories in June and his fourth top-six finish in a six-tournament run.

"This is probably the longest sustained stretch in my career where I've played tremendous golf each and every week," said Perry, who also won multiple times in 2005 and 2003.

Perry likely locked up a spot on the Ryder Cup team — his season-long goal — that will face Europe at Valhalla about 40 miles from his birthplace in Kentucky.

"I'm ecstatic," he said. "It really won't sink in until I'm actually putting on the red, white and blue."

With Tiger Woods sidelined by season-ending knee surgery, Perry trails just two active players in U.S. Ryder Cup standings and one in the FedEx Cup standings.

He's all but guaranteed to reach his goal of playing for his country in his home state. Perry also has improved his chances of winning $10 million in the PGA Tour's playoff.
