Del Potro advances, Fish out In Marseille, French qualifier Albano Olivetti, ranked 388th and playing in the main draw of an ATP event for the first time, stunned Mardy Fish 6-3, 3-6, 6-3 in the second round of the Open 13 Thursday. The second-seeded American rallied from a 3-1 deficit in the second set to level the match. But Olivetti jumped out to a 3-0 lead in the decider and kept his composure to earn the biggest victory of his young career. “That's just a number next to his name right now,” Fish said of Olivetti's ranking. Olivetti will meet Michael Llodra in an all-French quarterfinal. Llodra downed sixth-seeded Alexandr Dolgopolov of Ukraine 6-4, 5-7, 7-6 (5). Juan Martin Del Potro also advanced to the quarterfinals when a right foot injury forced Nikolay Davydenko of Russia to retire with the match level at one set apiece. The fourth-seeded Argentine lost the opening set 7-6 (6) but took the second 6-4 when Davydenko said he couldn't continue. He will next face Richard Gasquet, who cruised past Igor Kunitsyn of Russia 6-3, 6-2.
