I thought that the irony was that Dan made the first FH unforced error because, for about the first time in the set, Klahn actually hit a half-way decent sliced BH - took everybody by surprise, probably even Klahn.
He lost it when he threw away the *4-3 lead in the 'breaker with three really tame errors before Klahn even had a chance to make it a rally. That and the UE on championship point. Really disappointing stuff.
Klahn did come up with a couple of big shots in that final game, a brilliant bh down the line that set up an easy volley and the super running forehand pass that gave him mp.
