German golfer and former world number one Martin Kaymer will reportedly end his partnership with his coach Pete Cowen by the end of the year.
Kaymer, who has gone a year without a victory and is currently 39th in the world rankings, will now work exclusively with long-time coach Guenter Kessler.
According to Sport24, Kaymer said that Cowen, who has been helping him with his short game, had brought him a 'great deal' and extended his options on the golf course, although he added that the results are not to his satisfaction.
