Melzer injures leg at Malaysian Open
Vasek Pospisil of Canada advanced to the second round of the Malaysian Open on Monday after eighth-seeded Jurgen Melzer of Austria pulled out with a left leg injury while trailing 6-4, 2-0.
Pospisil will face Michael Yani, who defeated Brian Baker 6-3, 7-6 (4) in an all-American match.
In other first-round action, Igor Sijsling of the Netherlands ousted Malaysia's top-ranked player, Ariez Elyaas Deen Heshaam, 6-2, 6-1. He will face either Feliciano Lopez or Lukas Lacko of Slovakia.
Jimmy Wang of Taiwan beat Riccardo Ghedin of Italy 6-3, 6-3, maintaining his improved form in a year in which he qualified for the main draw at Wimbledon and reached the second round at the US Open.
