Pushing his record as the oldest winner on the 50-and-over Tour to 65 years, 10 months, 5 days, the German star broke a tie with Hale Irwin for the victory mark with No.46.

"I have my mother that's going to be 100 on August 4th, so I think I have good genes," Langer said. "Hopefully, I'll be around a few more years."

Seven strokes ahead on the back nine, Langer bogeyed the final three holes for a one-under 70 and a two-stroke victory over home-state favourite Steve Stricker.

"Never thought it would happen at a U.S Senior Open, but I'm very thrilled that the record of 46 wins happened this week," added Langer.

"It's certainly one of the greatest tournaments we ever compete in, and to beat this field, where everybody was here, especially Stricker and (Jerry) Kelly on their home grounds, is a very special feeling."

"I have my mother that's going to be 100 on August 4th, so I think I have good genes. Hopefully, I'll be around a few more years." - Bernhard Langer.

Langer finished at seven-under-par 277, with only eight players breaking par for the week. He shattered the tournament age record set by Allen Doyle in 2006 at Prairie Dunes at 57 years, 11 months, 14 days.

"There are a lot more aches and pains than 10 years ago," Langer said.

"I still enjoy the game. If I play like I did this week, I'm going to keep playing. There have been the odd week when I thought, 'What were you doing out here? Go home and play with the grandkids'."

Also, the 2010 U.S Senior Open winner at Sahalee outside Seattle, Langer extended his record for senior major victories to 12. He won the Chubb Classic in Florida in February to tie Irwin.

American Jerry Kelly was third at four-under.

Rod Pampling and Richard Green were the leading Australians in a tie for 27th at eight-over, five shots ahead of Mark Hensby.
