This match ended with a point penalty for Schwank!
K/K saved 2 mps, one on Dave's serve. At 10-9, Kas finally hit an ace that just touched the line (hawk-eye).
In the match tb, just everything went wrong for Argentina. Schwank threw his racket at least 5 times. At 2-7, Schwank got a warning for ball abuse and after the next point, he destroyed his racket, so that the score went directly from 2-8 to 2-10.
I don't rate K/K highly though, I wonder how they beat Dlouhy/Paes 6-3 6-0.
