Wawrinka has downed 2009 champion del Potro 7-6 (7-5) 4-6 6-3 6-2 to set up a semi-final showdown with sixth-seeded Kei Nishikori of Japan.

The Argentine appeared to have the number of his Swiss opponent In the first set opening up an early three game lead but Wawrinka fought back to take it in a tie-breaker (7-5).

The Olympic silver medallist, del Potro, needed only one break of serve in the second, to draw the match level at a set a piece but shoulder and knee problems appeared to unsettle the crowd favourite and he faded badly in the final two sets.
