LONDON -- Rory McIlroy has decided not to join the PGA Tour next year, which could mean as many as three of the top 10 players in the world ranking not belonging to golf's strongest tour.

McIlroy told British newspapers Monday evening that he found himself not wanting to be in America, especially during the FedEx Cup playoffs when the majors were over. In his rookie season on the PGA Tour, McIlroy closed with a 62 to win at Quail Hollow, and finished among the top three at the British Open and PGA Championship.

Lee Westwood, the new world No. 1, has not been a PGA Tour member for several years. PGA champion Martin Kaymer, who is No. 3 in the world, has indicated he will not join the U.S. tour next year.

McIlroy is No. 9 in the world. He says it's a great time for European golf.
