Juan Martin Del Potro, winner of the 2009 U.S. Open, beat Rafael Nadal 6-2, 6-4 in the Shanghai Masters on Saturday. The win means Del Potro will advance to play Novak Djokovic on Sunday in the final. Djokovic easily beat Jo-Wilfried Tsonga 6-2, 7-5 earlier in the day.
The loss was a shocking one for Nadal, who has put together a remarkable 2013. The Spaniard recently rose to the top of the world rankings and has won ten titles, including the French Open and the U.S. Open, on the season. But he was no match for the powerful Del Potro on Saturday, who jumped out to a 4-0 lead in the first set and didn’t look back.
