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.

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.
