Ruben Ramirez-Hidalgo is an intruiging player. A complete nobody who near the age of 30 worked himself up to be a competitive claycourter (2006-2007), beating Ferrer at RG, leading Federer 5-1 in the final set in Masters Series tournament.
His playing style is also of interest, he is the most technically pure moonballer on the tour
miles ahead of Nadal in esthetic terms, complete with a never-failing trademark grunt. A legend.
There was some tennis tournament going on at the university where I play tennis on Saturdays and I was watching this singles match between two guys. One of them literally moonballed every point. He used a Babolat racquet, and when he won (), he actually yelled, "VAMOS!!!!"
