(AP) Juan Martin del Potro of Argentina set up a potential Swiss Indoors title rematch against Roger Federer by beating Edouard Roger-Vasselin 6-4, 4-6, 6-2 in the semifinals on Saturday.
The top-seeded del Potro rallied after letting the second set slip away. He cruised in the third set against the 65th-ranked Frenchman.
Federer, who lost to del Potro in the 2012 final, played 40th-ranked Vasek Pospisil of Canada in the second semifinal.
A five-time champion in his hometown event, Federer is seeking just his second title this season.
