Rafael Nadal celebrates after winning a point against Nikolay Davydenko. Nadal won the match Saturday in Rome.

Rome ? Rafael Nadal extended his winning streak on clay to 76 matches and broke John McEnroe’s record for most victories on one surface by defeating Nikolay Davydenko, 7-6 (3), 6-7 (8), 6-4, Saturday in the semifinals of the Rome Masters.

McEnroe had a 75-match winning streak on indoor carpet between September 1983 and April 1985.

“It’s nice to have these records, but the important thing for me is to be in the final right now,” Nadal said.

In the final, Nadal will meet sixth-ranked Fernando Gonzalez, who ended Filippo Volandri’s impressive run with a 6-1, 6-2 rout.

“The guy seems like he’s unbeatable right now,” said McEnroe, who was at the Foro Italico for a seniors tournament. “Doesn’t he ever have a bad day or a headache once in a while or something? His intensity and quality level is just amazing.”

Nadal was broken while serving for the set in each of the first two sets and lost the second set – the first time he has lost a set in 14 matches on clay this season. But the Spaniard eventually wore out Davydenko to close out the match in 3 hours, 38 minutes.
