BASEL, Switzerland (AP) — Roger Federer will take on Novak Djokovic in the final of the Swiss Indoors as he tries for a fourth straight title in his hometown tournament.

Djokovic saved three match points before rallying to beat Radek Stepanek 6-7 (4), 7-5, 6-2 in their semifinal Saturday. Federer then beat childhood friend and fellow Basel-native Marco Chiudinelli 7-6 (7), 6-3 in the other.

“Obviously the home crowd will be behind him,'' Djokovic said of playing Federer in the St. Jakobshalle – where the 28-year-old Swiss was once a ballboy.

The third-ranked Djokovic trailed 5-4 in the second set and was 0-40 down before reeling off five straight points to win the game.

“I wouldn't say necessarily it was my good shots that prevented the loss. It was luck only,'' Djokovic said. “I just tried to get some first serves in and at least get that advantage. On this (hard-court) surface, it's crucial.''

He then broke the 14th-ranked Stepanek's serve for the first time before dominating the decider.

Djokovic's ATP Tour-leading 70th win this year carried him into his ninth final, also best on tour. He is 3-5 in title matches in 2009.

Chiudinelli had a set point in a thrilling first-set tiebreaker, but Federer struck a backhand crosscourt winner as his opponent advanced to the net, then took the next two points.

Federer broke serve early in the second set and quickly closed out the win. He has progressed without dropping serve in four matches, though Djokovic will be his first seeded opponent.
