That sweaty but happy contestant skipping across the court in the neon yellow shirt Sunday was Rafael Nadal, no longer No. 1 but waving his index finger anyway after a third-round victory in the Sony Ericsson Open at Key Biscayne, Fla.
It has been 10 months since Nadal won a tournament, but he showed some of his old championship swagger by rallying past dangerous wild card David Nalbandian, 6-7 (8), 6-2, 6-2.
Nadal, seeded fourth, remained on course for a showdown against the real No. 1, rival Roger Federer. They haven't met since May in Madrid, but their paths to the final became easier when No. 2 Novak Djokovic and No. 3 Andy Murray lost their opening matches.
A potential semifinal opponent is No. 6 Andy Roddick, who reached the final 16 by beating Sergiy Stakhovsky in 55 minutes, 6-2, 6-1.
Nadal will next face fellow Spaniard David Ferrer, who beat Ivo Karlovic, 7-6 (5), 6-3.
Advancing to the women's fourth round were Grand Slam champions Justine Henin and Kim Clijsters.
