What happened David?

It is very unhealthy to be David Nalbandian’s fan. He is absolutely unpredictable!!! When Nalby loses, I need at least one tennis-free day to recover, to digest his “I-don’t-know-why-I-am-playing-tennis” performance, and only then continue following the action. Nalbandian (the bookmakers’ fourth favorite) lost 6-1, 6-2, 6-3 in the third round of Australian Open to 22nd-seeded Juan Carlos Ferrero. It was unwatchable.

Que paso David?
