Donald, Kaymer seek No. 1 ranking

CASARES, Spain - Luke Donald will meet Martin Kaymer in the semifinals of the World Match Play Championship on Sunday, with the world's No. 1 ranking firmly in their sights after the elimination of top-ranked Lee Westwood.

Westwood fell to Ryder Cup teammate Ian Poulter in the final 16 Saturday on the Finca Cortesin course.

Second-ranked Donald struggled against Johan Edfors, needing a playoff to beat the Swedish outsider in the first knockout round. But he rediscovered his consistent best to defeat Masters champion Charl Schwartzel by 2 holes in the quarterfinals.

Kaymer, the former top-ranked player who has slipped to third, won two of the last three holes to defeat local favorite Alvaro Quiros by 2 holes in the last eight. The German player eased past Soren Kjeldsen, 3 and 2.

Belgium's Nicolas Colsaerts, who is No. 108 and claimed a first European Tour title at the China Open last month, will play Poulter in the other semifinal.

GLADSTONE, N.J. - Cristie Kerr, Paula Creamer, and Angela Stanford all advanced to the quarterfinals of the Sybase Match Play Championship.

There was only one major upset in the round of 16: Michelle Wie lost to Sophie Gustafson of Sweden, who sank a 25-foot birdie putt on the 18th hole at Hamilton Farm Golf Club to defeat the ninth-seeded Wie, 1-up.

FORT WORTH, Texas - Charlie Wi made a 32-foot birdie putt on the par-3 16th hole at Colonial, taking the lead after playing partner David Toms blew a 7-stroke advantage in the third round. Wi finished with a 4-under 66 to get to 13 under, a stroke better than Toms (74) and four ahead of John Senden (70).
