Martin Kaymer to play on PGA Tour

Former world No. 1 Martin Kaymer will be playing more of his golf in the United States in 2013, the PGA Tour announced on Tuesday.

The German will take up PGA Tour membership starting in January and is eligible due to his PGA Championship victory in 2010 at Whistling Straits. The 27-year-old will officially be a rookie despite his 10 wins on the European Tour, two of which also count as PGA Tour victories.

Joining Kaymer as rookies in 2013 are European Ryder Cup teammates Nicolas Colsaerts and Peter Hanson.

Colsaerts, 30, known as the "Belgian Bomber" due to his prodigious drives, ranked first in driving distance in 2012 on the European Tour at 318.6 yards per average drive. Hanson, 35, hails from Sweden and is currently second to Rory McIlroy on the European Tour's Race To Dubai, which is that tour's official money list.

Japan's Ryo Ishikawa, 21, and England's David Lynn, 39, are also headed to America next season to play on the PGA Tour. Ishikawa won't be a rookie because he joined as a special temporary member in March and played more than 10 events. Lynn's move is possible due to his second-place finish at the PGA Championship in August.

Colsaerts, Hanson, Ishikawa and Lynn are all eligible since their 2012 non-member earnings -- the money they won in PGA Tour sanctioned events like major championships and WGC events -- was greater than No. 125 on this year's money list.

The 2013 PGA Tour season begins with the winners-only Hyundai Tournament of Champions in Hawaii on Jan. 4. The first full-field event -- the Sony Open -- starts Jan. 10.
