Djokovic one win from No. 1 ranking

PARIS, June 2 (UPI) -- Novak Djokovic, undefeated in 2011, stands one victory from the world No. 1 men's tennis ranking and his next opponent is the last man to have beaten him.

The French Open heads into the men's semifinal round Friday with the top four seeds having advanced this far. Djokovic will be taking on world No. 3 Roger Federer and top-ranked Rafael Nadal, seeking a record-tying sixth French Open title, faces fourth-seeded Andy Murray, who is 0-3 in Grand Slam finals.

Djokovic has won all 41 of his matches this year, winning the Australian Open and six other tournaments along the way. He also won his final two matches in 2011, when he led Serbia to the Davis Cup title.

His most recent loss was Nov. 27 when Federer was a straight-set winner at the semifinals of the World Tour Finals. Federer is 13-9 versus Djokovic in his career but Djokovic has won their three meetings this year.

Federer hasn't lost a set in his current French Open run, taking a 6-4, 6-3, 7-6 (7-3) decision over Gael Monfils in the quarterfinals Tuesday. Djokovic will be well-rested for Friday's semifinal as he hasn't played since Sunday. His quarterfinal opponent pulled out with an injury.

However, if he wins Friday -- even if he loses to Nadal in Sunday's men's singles title match -- Djokovic will be the world No. 1-ranked player on Monday. It would be the first time since Feb. 1, 2004, that someone other than Federer or Nadal would on top of the rankings.

Nadal is 10-4 lifetime against Murray. That includes a 3-0 record on clay, but Murray is in crowded company among those having a losing record to Nadal on clay courts. Nadal is 43-1 all-time at Roland Garros and has won 225 matches overall on clay.

If he can win Sunday, he will match Bjorn Borg's Open Era record of six French Open championships.
