It all started with a birdie splash from a greenside bunker on the par-4 7th hole at Sheshan International Golf Club. Eleven holes and eight more birdies later, Martin Kaymer was signing for a 9-under 63 that gave him a three-shot victory at the World Golf Championships-HSBC Champions. Kaymer, who entered the day five shots behind overnight leader Fredrik Jacobson, opened his round with six pars before his assault on the course got him to 20 under and into the winner's circle. In a way, this victory brings things full circle for Kaymer, who lost in the finals of the first WGC of the season, the Accenture Match Play Championship. A year after earning his first major championship in the final major of the year, Kaymer picks up his first WGC in his final 2011 opportunity. Jacobson, who had played so solidly through three rounds, settled for second-place honors following his Sunday 71. Graeme McDowell finished third at 16 under while Charl Schwartzel, Paul Casey and Rory McIlroy shared fourth at 15 under. Click here to read more about Round 4 at Sheshan International
