World number one Rafael Nadal was dumped out of the Shanghai Masters tennis tournament on Saturday by inspired Argentine Juan Martin del Potro, who blew the Spaniard away with a relentless display of brutal hitting to set up a final against Serbian Novak Djokovic.
The giant Del Potro, fresh from winning the Japan Open, went into the semi-final at the Qizhong Tennis Centre trailing 8-3 in head-to-heads, but rocked Nadal with a double break in the first set and kept up the pressure to win 6-2, 6-4.
Earlier, top seed Djokovic swept aside Jo-Wilfried Tsonga of France 6-2, 7-5 to earn the chance to defend his title.
Nadal has enjoyed one of the best seasons of his career, winning 10 titles including the French Open and the US Open, and came into the match with all eyes on yet another showdown with Djokovic.
But the 13-time grand slam champion was given the run-around by the sixth seed, who launched a sustained and blistering all-court attack from the start, achieving the rare feat of out-hitting his illustrious opponent.
Dominating from the baseline on both forehand and backhand sides, Del Potro raced into a 4-0 lead in the first set as Nadal desperately searched for a foothold.
A single break was enough in the second set for the inspired Argentine, who hit a total of 28 winners and 31 unforced errors, landing 80 per cent of first serves.
