ESTORIL: Second seed Nikolay Davydenko shrugged off a sluggish start, claiming his ninth victory in succession to move into the quarter-finals of the Estoril Open.

The Russian, who won the Miami title little more than a week ago over Rafael Nadal, staged a comeback to defeat Czech Ivo Minar 2-6, 6-2, 6-4 at the Estadio Nacional. Davydenko is riding a run of form after also helping Russia into the Davis Cup semi-finals at the weekend over the Czechs.

But the Russian is unsure of his confidence as he ventures onto clay.

"I was leading 4-1 in the third set and I was not sure if I could win the match," said the player with a 22-5 record this season. "At this moment, I don't have particularly good confidence. I need more matches on the clay."

The world number four has a hit-or-miss history in Portugal, losing three times in the first round while winning the 2003 title and playing a final two years ago.

He will on Friday face seventh seed Marc Gicquel, who beat fellow Frenchman Thierry Ascione 7-6 (7/2), 6-3.
