Top-seeded Rafael Nadal advances to quarterfinals on clay in Buenos Aires
{{#rendered}} {{/rendered}}Top-seeded Rafael Nadal beat local qualifier Facundo Arguello 6-4, 6-0 on Wednesday to reach the quarterfinals of the Argentina Open.
Nadal has yet to reach a final in three tournaments this season and was beaten in the semifinals last week in Rio de Janeiro, ending his 52-match unbeaten run on clay.
He has had illness and injury problems the last few seasons, and this year he says he's fit but not yet match conditioned.
