Gulbis - Del Potro
over 20.5 @ 1.909 (or -110)
pinny 5/10

Ok, so here we are at 1/4 stage where infamous Gulbis takes on mighty Argentinian. Gulbis has won 2 lousy matches so far, but Huan Martin has not shown his best play as well. I mean Blake almost got him.
I do not think that it is going to be a blow out and we might see at least one close set (possibly a tie-break).
And yes, I would not be too surprised to see Gulbis take this one away from his opponent.

from other matchups I like

In good form is this Chinese player. Let see if he can upset the local star

T. Bellucci -3 @ @ 1.952 (or -105)
pinny 4/10

One match was enough to understand that Bogomolv has no chances here. 2 easy sets for Brasilian.
