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.

Chiudinelli was playing in the first semifinal of his injury-affected career, and earned a place in the main draw of next week's Paris Masters.

Ranked No. 884 a year ago, Chiudinelli will be near the top 50 when the new list is published Monday.

Djokovic had beaten Stepanek easily in the last 16 at the U.S. Open in September.

But the 30-year-old Czech forced him to save two break points in the opening game, and took control of the first-set tiebreaker with a pair of overhead winners.

Djokovic's first serves faltered in the second set, and a double fault gave Stepanek three match points.

Djokovic responded with heavy serves and ground strokes, and needed just one set point on his next service game. He converted it with a forehand winner.

In the decider, Djokovic got service breaks in the first and seventh games before closing out victory.
