Calling any loss from a leading position a "choke" renders the concept meaningless. Dumping returns in the net when your cramping opponent is just spinning the serve in? Yes. Missing a groundstroke the same way you do dozens of other times in a match, then having your opponent rip a forehand winner? No.
Meanwhile, Anderson was the better player in the body of the first two sets, and it was only his becoming a double fault machine in the tiebreaks that had Ilhan in that position to begin with.
2nd set Tiebreak was really bad and nervous from both...
so many double faults from Anderson... This is really unbelievable with such a good serve.
Ilhan was weak mentally (as well), he should have won set 2.
