Djokovic into Wimbledon final; to get No.1 ranking

Novak Djokovic cut down Jo-Wilfried Tsonga 7-6 6-2 6-7 6-3 on Friday to reach his first Wimbledon final and guarantee becoming world number one next week.

The Serbian second seed looked to be cruising to a straight-sets victory but Tsonga suddenly sprung to life in the third set, breaking Djokovic's serve to force a tiebreak which the 12-seeded Frenchman won 11-9.

But Djokovic held his nerve to secure an early break in the fourth set and Tsonga, who fought back from two sets down to beat six-times champion Roger Federer in the quarter-finals, could not respond.

Djokovic, now certain to knock Rafa Nadal off the top of the rankings, will play top seed Nadal or Briton Andy Murray in the final on Sunday.
