( CNN ) -- Martin Kaymer has claimed golf 's No . 1 ranking after reaching the final of the World Match Play tournament in Arizona on Saturday . The German toppled Englishman Lee Westwood as he first beat Spanish veteran Miguel Angel Jimenez in the quarterfinals and then ended the hopes of American Bubba Watson . The 26-year-old will face European Ryder Cup teammate Luke Donald in Sunday 's final at Dove Mountain 's Ritz-Carlton course after the Englishman made light work of his matches against Americans Ryan Moore and Matt Kuchar . `` It has taken me only five years to get to number one . For myself , my family and the people I work with , it 's a great achievement , '' Kaymer told reporters . `` I was not thinking about the number one spot as I was sure I would get the opportunity again over the next few weeks , I just wanted to win the match . `` Luke is probably one of the best match-play players in the world . We get along well , but because it 's a final it will add more pressure . '' Westwood had been top of the rankings since the end of October , when he ended Tiger Woods ' record reign , but he lost in the second round of the $ 8.5 million tournament . European Tour No . 1 Kaymer won both of his matches at the 18th , surviving a late rally from Jimenez after leading by four holes at 14 . Kaymer closes on golf 's top spot . Jimenez -- at 47 the oldest man in the initial 64-strong field -- reduced the gap to one as Kaymer lost his accuracy , but then failed to find the green in regulation at the last . Kaymer was pegged back three times by Watson -- who earlier beat compatriot J.B. Holmes at the first extra hole of their quarterfinal -- but won 15 and 16 before the left-hander birdied 17 . Watson struggled to find the green at 18 , and Kaymer sank an eight-foot par putt to seal victory . Sunday 's opponent Donald can climb to third in the world rankings with victory in the final , which would end his five-year title title drought in U.S. events and earn him $ 1.4 million . Westwood and Mickelson crash out of Match Play . The 33-year-old opened the day in fine style with a 5 & 4 win over Moore as he led from the first green , and won three holes in a row from the eighth before his fifth birdie of the match at 14 sealed it . Donald then thrashed U.S. Ryder Cup player and 2010 PGA Tour money list champion Kuchar 6 & 5 in the first semifinal to be completed . He fired six birdies in 13 holes in increasingly windy conditions at Dove Mountain 's Ritz-Carlton course . Kuchar earlier eliminated 2009 PGA Championship winner Y.E . Yang , defeating the 39-year-old Korean 2 & 1 in the quarterfinals . Woods follows Poulter out of WGC-Match Play championship . Yang , who beat U.S. Open champion Graeme McDowell on Friday , was never ahead in the match and trailed by four holes after the eighth , then Kuchar matched his four consecutive pars to 17 . Watson came from 5-down after 10 holes to beat Holmes at the 19th hole , which his compatriot bogeyed to go behind for the first time in the match . The semifinals were originally scheduled for Sunday , but warnings of adverse weather meant they were brought forward . Organizers hope the final will not be disrupted by the forecast drop in temperatures which could bring snow to the desert course .
