Ireland's McIlroy decides to join PGA Tour in 2010

HONG KONG -- Rory McIlroy has decided to join the PGA Tour next year with hopes of moving up in the world ranking.

McIlroy, a 20-year-old from Northern Ireland, said Wednesday at the Hong Kong Open that he will be competing against stronger fields in the United States, which should make him a better golfer.

He already is No. 17 in the world, despite turning pro only two years ago.

McIlroy made in the cut in all four majors this year, tying for third at the PGA Championship in August. As a U.S. member, he will have to play 15 times next year, although that includes the majors and World Golf Championships.
