NEW YORK (AP) _ Jim Courier, who won four Grand Slam titles in the 1990s, is retiring after a 13-year professional tennis career, USA Today reported Monday night.

Courier, 29, was ranked No. 1 in the world for 58 weeks during the `90s and was one of six men in the Open era to reach the finals of all four Grand Slams.

``I wouldn't trade anything for one more title, one more match won or lost,'' Courier, who will be an analyst for TNT at Wimbledon this summer, told the newspaper. ``I feel full.''

Courier, of Dade City, Fla., lost to Sweden's Thomas Enqvist in the second round of the Ericsson Open, his last tournament, on March 25. His last title came in April 1998, when he beat Michael Chang in Orlando, Fla.

Courier, known for his baseball caps and powerful forehand, won the French Open twice (1991 and `92) and the Australian Open twice (1992 and `93). His five five-set Davis Cup victories is an American record, and the United States was 13-1 when he played on the team, including championships in `92 and `95.
