World number one Rafael Nadal was dumped out of the Shanghai Masters 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 Novak Djokovic. The giant Del Potro, fresh from winning the Japan Open, went into the semi-final at the Qizhong Tennis Center 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.
