Swiss legend Roger Federer defeated Frenchman Richard Gasquet on Friday to set up a Shanghai Masters semi-final clash against Juan Martin del Potro.

The 36-year-old Federer was relatively untroubled as he eased to a 7-5, 6-4 victory over the unseeded Gasquet.
He is scheduled to face Del Potro in the last four, although the Argentine’s participation is in doubt after he injured a wrist in his quarter-final victory.

Juan Martin del Potro headed to a hospital for a scan on his left wrist after a nasty fall while winning his quarterfinal encounter.
Del Potro tumbled on the court at 2-2 in the third set against Viktor Troicki of Serbia and instinctively tried to break the fall with his left wrist. Del Potro, who has undergone surgery on both wrists, conferred with a trainer as he repeatedly shook his wrist.
Del Potro ended up breaking Troicki’s serve in that fifth game and prevailed 4-6, 6-1, 6-4.

“I don’t know how my wrist is after I fell down,” del Potro said before leaving for a local hospital. “I felt something wrong in that moment, but I continued to play, just playing (backhand) slices just to finish the match. I’m going to the hospital to see what the MRI says, and what the doctor says.
“Then I will take a decision for tomorrow. I would like to play and be 100 percent.”
