Djokovic has been No. 1 for a year

Novak Djokovic reached the one-year mark of being the No. 1-ranked player in men's tennis Monday and will take that ranking to Wimbledon next week. Djokovic, who has won three of the last four major tournaments and finished second in the other -- the recent French Open -- has been on top of the rankings for 52 weeks. That ties Andre Agassi for the 12th longest string of consecutive weeks at No. 1, with John McEnroe (53) in 11th, Rafael Nadal (56) 10th and McEnroe (58) again at ninth. There are no changes in the Top 10 this week -- the final Monday before the seedings and draw are determined for the Wimbledon Championships. The third major tournament of the tennis year begins next Monday and is to wrap with the men's singles final July 8. Djokovic has 12,280 ranking points and Nadal is second at 10,060. Roger Federer (9,435) comes in third and Andy Murray is fourth at 6,980. Those four players have grabbed 14 of the 16 semifinal spots in the last four Grand Slam events. Djokovic and Nadal have played in each of those finals. Jo-Wilfried Tsonga is fifth with 5.230 points and David Ferrer is close behind at 5,180 in sixth. Tomas Berdych has 4,685 points and is ranked seventh. Janko Tipsarevic (3,200) is eighth, just 20 points up on No. 9 Juan Martin del Porto, and John Isner (2,655) completes the Top 10. Marin Cilic won last week's AEGON Championships in London and jumps seven places to No. 18 in the rankings. Tommy Haas defeated Federer in the Gerry Weber Open final Sunday and improves his ranking 38 rungs to No. 49.
