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. Jaidee, last year's runner-up, was eliminated.
American Ryder Cup player Patrick Reed also advanced after beating Jamie Donaldson 3 and 2, and will play Geroge 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.
