Feliciano Lopez caused a massive upset when he defeated fifth seed Nikolay Davydenko 6-4 4-6 7-5 to secure his place in the Dubai Open final.

The unseeded Spaniard beat Andy Murray's conqueror to set up a showdown with American Andy Roddick on Saturday.

Lopez - ranked 41 in the world - came back from 2-5 down in the final set to secure his victory over the Russian.

Roddick beat Novak Djokovic 7-6 6-3 and said: "I'm excited. I played well and I played the right way."

The sixth seed added: "I had to, otherwise I wasn't going to win. He wasn't missing at all in the first set.

"He wasn't missing serves and I couldn't get into his service games."

Roddick looked in fine touch against the Australian Open champion, making the decisive break in the eighth game of the second set to go 5-3 up before serving for the match.

"I definitely had to try to stay the course and try and tough out some games before I got the momentum on my side there in the tiebreak," said Roddick.

Lopez made the worst possible start against Davydenko, winning just one point in his first three games as the Russian cruised to a 4-2 lead.

But the 26-year-old rediscovered his rhythm and promptly won the next four games to take the set.

The second set was a closer affair, but Davydenko hit back with a break in the ninth game to level the match.

Lopez had looked beaten at 5-2 down in the final set, but completed an impressive comeback by clinching the next five games to win the game.

"It was really good for me because to win a match from 5-2 in the third is tough," said Lopez. "I made it but I think I was a little bit lucky."

A disappointed Davydenko blamed errors at crucial times for his defeat.

"At 5-3 I thought I would win the match," he said.

"It was bad luck. On a few points on my serve I made a mistake and he played pretty well, tried to make no mistakes and pushed the ball back.

"It should have been my match but he won."
