Martin Kaymer said on Sunday he has not decided whether to take out membership to the PGA Tour next year.
The 25-year-old German was speaking after recording a third straight tournament victory at the Alfred Dunhill Links Championship, adding to his wins at the PGA Championship and the KLM Dutch Open.
Those wins have made Kaymer the hot favorite to become the new European number one by winning the Race to Dubai money list next month.
He now has a ?995,580 ($1.3 million) lead in the money table with a maximum of seven events still to be played.
However, Kaymer is still considering whether to launch his first challenge for the U.S. tour?s FedEx Cup title next year.
''I get that question a lot,'' Kaymer said. ''But I cannot answer it at the moment. For me the main goal now is to win the Race to Dubai this year and I know I have still a few weeks in which to decide if I am going to join the PGA Tour.
''I cannot answer the question, because I don't know and at the moment it's not something that I care about.''
Lee Westwood, who is poised to take Tiger Woods' place at the top of the world rankings, announced last week he will not take out PGA Tour membership in 2011, but U.S. Open champion Graeme McDowell has said he will take up his card.
