Schwank and Zeballos did well to win all those doubles matches at Wimbledon and the US Open, but the only win I'd rate particularly highly is that against Benneteau & Llodra (Wimbledon QF). While tough, the other pairings featured players with particularly suspect returning skills and/or a lack of exceptionally skilled shotmaking...typical 'doubles specialist' combinations.
I don't doubt that they are good
, but I do think that it is easy to overrate them.
I'll be very interested to see whether Nalbandian plays a part in the doubles on Saturday. It will be a tough decision, especially as Schwank & Zeballos are a competent pairing...will Vazquez risk splitting them up? Would Nalbandian actually significant boost their chances in that match? I'm not sure that he would tbh.
And there is also the problem that Dave plays the 2nd rubber on Friday...that is likely to be a physical match, and he'd have less time to recover. So, whatever the match outcomes on Friday, I'm not too sure whether he'll play the doubles (even if Argentina are 0-2).
