I'm adoring his topspin capabilities. Zeballos is one hell of a player, its a shame he is 27 and only has a few good years left on the tour.
Tommy Haas is nearly 35, likewise Stepanek. Phau is 32 and recently broke back into the top 100, Ramirez Hidalgo likewise at 34. Ferrer just had the best season of his career at 30.
Plenty of players in this day and age performing to a high level well past 30.
As I said before, he's been floating around #100 for ages. This week has been a bit out of the blue.
