Stanislas Wawrinka's wonderful run at Australian Open leads to shake up in rankings

Stanislas Wawrinka’s wonderful run at the Australian Open has propelled him to third in the rankings, making him Switzerland’s No.1.

Nadal has cemented his world No. 1 ranking by reaching the final and will be hard to shift from the top but below him the ranking will change.

Novak Djokovic remains No. 2, but both Andy Murray and Roger Federer are falling, to numbers six and eight respectively.

Federer, who played beautifully to reach the semis, was outplayed by Nadal and his chances of adding to his record haul of 17 grand slam titles are receding.

At number four is Argentine Juan Martin del Potro.

Spain’s David Ferrer will slip from three to five in Monday’s ranking list, Dawn reports.

Bulgaria’s 22-year-old Grigor Dimitrov will enter the world’s top 20 for the first time.
