With his title in Buenos Aires Nadal has slipped past Borg and Sampras. I would certainly rate him higher than Borg but Sampras' long-ass run at No. 1 puts him a bit ahead imo. Also 2 years ago I said that Federer won't ever be close to Lendl but 10 titles in 2 years are not impossible to do. I don't see him winning another Slam but 1-2 Masters titles per year and some 250-500 are definitely within reach.
