BASEL, Switzerland — Roger Federer set up a rematch with Juan Martin del Potro for his hometown Swiss Indoors title by beating Vasek Pospisil in a tense semifinal Saturday.
Federer advanced to his eighth straight Basel final with a 6-3, 6-7 (3), 7-5 victory over the 40th-ranked Canadian.
The third-seeded Federer faltered when serving for the match at 5-3 in the second set. He fell behind 3-1 in the decider before rallying in front of a capacity crowd of 9,200 at St. Jakobhalle.
“Watching is actually worse than playing itself,” said Federer, describing the atmosphere as a “roller-coaster ride.”
“It’s almost nice to be part of it even though, in the moment, it could have been easier,” he added.
Earlier, defending champion del Potro also let the second set slip away against an unseeded opponent before beating Edouard Roger-Vasselin of France 6-4, 4-6, 6-2.
