Lucho and Pablo beat Dlouhy/Paes 6-4, 6-4
There is a Peruvian in a Grand Slam QF 14 years after Yzaga beat Sampras at the 1994 US Open.
This win doesn't surprise me at all.
I've always said that Lucho has the level of a Top 15 doubles player. Despite the fact that he's never taken doubles seriously he has 5 titles and now a Grand Slam QF.
Step by step Lucho, You have the power!
