CASARES, Spain: Luke Donald will meet Martin Kaymer in the semifinals of the World Match Play Championship Sunday, with the No. 1 spot firmly in their sights following the shock elimination of top-ranked Lee Westwood in Andalusia. Westwood's surprise defeat to Ryder Cup teammate Ian Poulter at the last-16 stage Saturday left him vulnerable at the top of the rankings. Second-ranked Donald struggled against Johan Edfors, needing a playoff to beat the Swedish outsider in the first knockout round, but rediscovered his consistent best to beat Masters champion Charl Schwartzel by 2 holes in the quarterfinals. Kaymer won two of the last three holes to defeat local favorite Alvaro Quiros by 2 holes in the last eight. The German player earlier eased past Soren Kjeldsen 3 and 2. Donald or Kaymer will go to No. 1 if either wins the tournament on the Costa del Sol. The two met in the final of the Accenture Match Play in Arizona in February, with Donald emerging victorious 3 and 2. “I suppose I have the upper hand psychologically,” said Donald, who has never been No. 1 but has been a persistent challenger at the top of the rankings in recent weeks after a consistent run of results in the United States.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. But all eyes will be on the Donald-Kaymer match-up, especially with the bigger prize hinging on the result. Colsaerts is the tournament's surprise package. He beat two-time US Open champion Retief Goosen and sixth-ranked Rory McIlroy in the group stages before defeating Venezuela's Jhonattan Vegas 2 and 1 in the last 16 and then No.5-ranked Graeme McDowell by the same score. Toms ties PGA 36-hole record In Fort Worth, Texas, American David Toms fired his second consecutive eight-under 62 at the $6.2 million Colonial event to equal a PGA Tour record and open up a seven-shot lead Friday. Despite a rain delay of more than two hours, Toms, 44, shot another bogey-free round to tie Pat Perez's 36-hole record of 124. Perez shot opening rounds of 61 and 63 at the 2009 Bob Hope Classic. Toms finished with four birdies on the eight holes he completed after play restarted. Australians Steven Bowditch (64) and John Senden (66) were tied for second place with South Korea's Charlie Wi (67) and America's Mark Wilson, who played alongside Toms, (66). Wi and Bowditch completed their rounds before the delay. Favorites lead way Bae Kyeong, Choi Na-yeong, Lee Meena and Park Inbee won second round matches as four South Koreans reached the third round of the $1.5 million Sybase Match Play Championship on Friday. Tseng Yani of Taiwan and Japan's Ai Miyazato were other Asians who moved Friday as the favorites continued to dominate winning seven of 10 matches. Top seeded Choi beat Britain's Karen Stupples in 20 holes while world No. 1 Tseng defeated American Jenny Suh 3 and 2 at the Hamilton Farm Golf Club.
