Estoril, Portugal (Sports Network) - Former titlists David Nalbandian and Carlos Moya were among Thursday's second-round winners at the clay-court Estoril Open.

The top-seeded Nalbandian, who captured this event in 2002, got past French lucky-loser Jeremy Chardy 6-1, 7-6 (7-0), while the sixth-seeded Moya, the 2000 champ here, topped Argentine qualifier Gustavo Marcaccio 6-1, 7-5 on Day 4.

The 2005 Tennis Masters Cup titlist Nalbandian will face Portuguese wild card Frederico Gil in Friday's quarterfinals, while Moya will encounter his fellow Spaniard Guillermo Garcia-Lopez.

The heavy crowd favorite Gil upended fifth-seeded Russian Dmitry Tursunov 4-6, 6-4, 6-1, while Garcia-Lopez outlasted Argentine Carlos Berlocq in a marathon bout, 6-7 (11-13), 7-5, 7-6 (7-5).

Friday's other quarters will pit second-seeded Russian Nikolay Davydenko against Luxembourg's Gilles Muller and Spaniard Albert Portas versus American Justin Gimelstob. Davydenko titled here in 2003.
