The World number one Roger Federer breezed into the Swiss Tennis Indoors semi-finals but the home crowd's hopes of an all-Swiss final were dashed when Novak Djokovic rallied to beat Stanislas Wawrinka.
Federer overcame Evgeny Korolev 6-3 6-2 and will face unseeded compatriot Marco Chiudinelli, a 6-1 6-3 winner over Frenchman Richard Gasquet.
Wawrinka, the other home quarter-finalist, won the first set against the world number three and was a break up in the second.
But the Serb broke back, won the second set tiebreak and eased through the third to win 3-6 7-6 6-2.
Djokovic will face fifth seed Radek Stepanek who beat fourth seed Marin Cilic 4-6 6-3 6-3.
