Kaymer hard at work to end barren spell

Fifteen months ago, Martin Kaymer was the world's top-ranked golfer and a good bet to become a serial winner at the majors after capturing his first at the U.S. PGA Championship in 2010. Now, amidst a slump in form that has seen him drop to No. 14, the German has been ''getting completely away from golf'' by spending an afternoon weeding and mowing lawns in his grandmother's backyard. ''Maybe you can call it therapy,'' was Kaymer's reaction to his Monday spent with his 85-year-old grandmother. Kaymer shot weekend rounds of 78 and 77 at the French Open last week to finish last of the 70 players who made the cut, with a total of 16-over 300. He has gone eight months without a victory.
