Novak Djokovic's perfect season is still intact, his winning streak is still alive and his clay-court form still looks devastating after he reached the third round of the French Open when Victor Hanescu retired Wednesday because of injury.
The second-seeded Serb, who joined 2009 champion Roger Federer in the third round at Roland Garros, improved to 39-0 in 2011 after Hanescu retired while trailing 6-4, 6-1, 2-3. Djokovic also has won 41 straight matches dating to last year's Davis Cup final.
If he makes the final, Djokovic will be assured of the No. 1 ranking in men's tennis for the first time.
