ASH, England — Top-seeded Henrik Stenson defeated Thongchai Jaidee 2 and 1 to reach the quarterfinals undefeated after the opening three rounds of the World Match Play Championship.

Stenson sealed the win when his wedge shot into the 17th green spun back into the hole for birdie on the London Club course. He finished with an eagle and six birdies on the final day of round-robin play and will play fellow Swede Jonas Blixt in the quarterfinals on Saturday. Thongchai, last year’s runner-up, was eliminated.

American Ryder Cup player Patrick Reed, a former University High golfer, also advanced after beating Jamie Donaldson 3 and 2, and will play George Coetzee of South Africa.

In the other quarterfinals, Victor Dubuisson of France faces Mikko Ilonen of Finland and Joost Luiten of the Netherlands takes on Pablo Larrazabal of Spain.

Luiten, overlooked for European Ryder Cup selection in favor of Lee Westwood, had been 3 down to McDowell after eight holes before going ahead for a first time with a birdie at 17 and then also managing to birdie the last.

Reed, who was undefeated in the recent Ryder Cup, was 2 up after just four holes and then moved to 4 up with a birdie at 12.

“It feels good to win as today I made a lot of clutch and solid putts,” he said. “This is one of those events I’ve always wanted to play. I watched it last year on TV back home. Justine, my wife, goes, ‘I think we need to play there next year or whenever we get a chance.’ And luckily we got an invite this year and I couldn’t pass it up.”
