No way DY will ever be top 20. He will also never win a top tier tourny. Can someone please explain to me how his record for someone who has this much tour experience is good??? Look at every other successful player and by this much tour experience as DY has, they are way ahead (I'm not talking about Nadal, McEnroe, Sampras, Agassi, Borg, Becker, Chang, Wilander, Courrier, etc..all these guys are freaks of nature and DY will never be at this level). I'm talking about: Murray, Gasquet, Monfils, Querry, Djokivic, Safin, Berdych, Del Potro, Malavai Washington, Todd Martin, etc...DY is not even close to being on track to these guys and this is your top 20 tier.
The match with Blake was ugly and the only positive was that both players played bad so it seemed dramatic (like watching a women's match with 15 breaks of serve). Blake and DY should be fined for their pathetic performance.
