I've began watching this mtach from the start of the second set. What was at the end of the first? Had Ferrero some setpoints?
Well, Gabashvili challanged a return from Ferrero, but AFTER he actually played the point - and Ferrero's return was indeed out. So, in stead of deuce, it meant the set for Gaba.
I always thought that one should either play the point OR challenge it immediately?
Ferrero didn't complain at all so I guess I'm wrong about this - or he isn't actually interested in this tournament at all. Judging from the way he's playing right now this could well be the case.
