Davydenko through in Marseille

Marseille - Nikolay Davydenko hit nine aces and did not face a single break point as he beat Andreas Beck of Germany 6-1, 7-5 on Tuesday to reach the second round of the Open 13.

Davydenko, a semi-finalist at the ABN Amro World Tennis final in Rotterdam last week, broke Beck's serve three times in the match. The Russian next faces fourth-seeded Juan Martin del Potro of Argentina for a place in the quarter-finals.

In other first-round matches, Frenchmen Nicolas Mahut and Albano Olivetti, and Russia's Igor Kunitsyn all advanced in straight sets, while David Goffin of Belgium was up 6-2, 1-0 against Adrian Mannarino when the Frenchman retired.

Mahut hit 12 aces in beating Arnaud Clement 6-3, 6-4 and will play another Frenchman, top-seeded Jo-Wilfried Tsonga, in the second round.

Olivetti did not face a break point in his 6-4, 6-3 win over Matthias Bachinger of Germany, but Kunitsyn saved seven of the eight he faced before getting the better of Spain's Roberto Bautista-Agut, 6-4, 6-4.

Later Tuesday, No. 5 Richard Gasquet of France was playing Go Soeda of Japan.
