Navarro, a Spaniard ranked No. 104, used an unusual serve-and-volley game on the slow clay court to surprise the Russian and also played many drop shots from the baseline to mix things up.
"It's not simple to play against him," Davydenko said. "The first couple of matches in a tournament are usually tough for me."
Fourth-seeded Victor Hanescu of Romania also advanced to the second round by beating qualifier Dominik Meffert of Germany 6-4, 7-6 (6), while Lukasz Kubot of Poland beat Pablo Andujar of Spain 6-2, 6-4 in a match between two qualifiers.
