To be fair, I think that Del Potro did tank to be honest. He wouldnt lose to Llodra in straights if it were a grand slam.
Simon, Berdych, Tsonga, and Tipsarevic are just losers, especially Tipsarevic.
BTW I said slams, but I meant to say Masters, obviously.
It would be D-Pot 2nd biggest achievment of his carreer. While in WTF he doesn't stand much of a chance, tbh. IF it was a tank (and I'm pretty sure it wasn't) it was the dumbest tank of history, IMO.
