Ferrer had his hands full with the Croatian in the first two sets but prevailed 6-4, 6-7 (5-7), 6-1 and advanced to Sunday's championship match against Alexandr Dolgopolov of Ukraine.
Ferrer will be looking to add a fourth Valencia title to his resume Sunday. He has won five titles this year but his most recent one was in Bastad in July.
Dolgopolov advanced Saturday with a 6-4, 6-2 win over Austrian Jurgen Melzer. Dolgopolov won a U.S. Open tuneup this year and was runner-up to Andy Murray in Brisbane.
