Philipp Petzschner: Biggest Choker in Tennis?

For the third consecutive Grand Slam, Phillipp Petzschner blew a two-sets-to-none lead on his way to crashing out of the singles draw.  

Petzschner's loss in Paris to wild card Carsten Ball (6-3 7-6(4) 2-6 5-7 7-9) follows losses at the 2010 Australian Open to Florian Mayer (6-0 6-2 4-6 2-6 2-6) and the 2009 US Open to Juan Carlos Ferrero (6-1 6-3 4-6 2-6 4-6).

The Ferrero loss is definitely the most respectable of the three, but still it can be fairly said that no player should ever lose a best of five match when he's lost only four total games in winning the first two sets.

You can talk all you want about Jana Novotna, Dinara Safina, or whichever other icon of mental frailty you want, but the real chokers are the ones who never even reach the upper echelons because their brains won't let them.
