Tipsarević

It's 12:17 am of a nascent Saturday morning and the only thing keeping me awake is this young, fine, gutsy Serbian player, who's as the time, on his way to have a one set advantage over the FED.

His body language screams never-say-die, and by now, I feel I owe him a sleepless night.

... and it just happened, he's gone one set ahead.

I know the Roddick debacle came just 24 hrs earlier, but this... would be so much more GRAND.

Stay tuned, fellas.
