Second-seeded Andreas Seppi from Italy and Benoit Paire of France reached the Serbia Open final on Saturday.
Seppi rallied to beat fourth-seeded David Nalbandian 2-6, 6-2, 7-5.
Nalbandian easily won the opening set, but Seppi returned the pressure and eventually broke at 5-4 in the third to serve out the match.
Nalbandian committed seven double-faults.
Seppi said it took him a while to adapt to playing an evening match. He said he expected a tough match from Paire on Sunday.
Paire upset top-seeded Pablo Andujar of Spain to reach his first final on the ATP Tour.
Paire served seven aces in winning 6-3, 1-6, 6-3.
Andujar started off well, breaking early in the first set, but Paire responded by breaking twice for a 5-3 lead and serving out the set.
Paire previously eliminated sixth-seeded Fabio Fognini, Guillermo Garcia-Lopez and third-seeded Jarkko Nieminen.
