Davydenko, the top seed and defending champion, beat unseeded Jiri Novak of the Czech Republic, 6-2, 6-2. The 32-year-old Pavel moved up in a walkover against seventh-seeded Luis Horna of Peru, who was unable to play Friday because of a back ailment.
"I'm glad that this match only lasted for (1 hour, 8 minutes)," Davydenko said. "My goal is always to be on the court as short a time as possible, which I did manage today."
Pavel, who trails Davydenko, 2-1 in past matches, will be playing in a final for the eighth time in his career. He has not won a tournament since 2001.
Davydenko, who also won this event in 2003, raised his match record for the year to 30-14.
The winner of Saturday's championship match will pocket $44,100.
