I just wonder how would you consider a close match? Or 2 players are at least same level. Is 6-3 6-3 a close or 6-1 7-6 a better one? Someone told me it's kind of subjectives to each of the player but I would argue for some evidence. You cannot say 6-1 6-2 is a close match since one side is obviously better than the other. How about this: 6-1; 6-7; 6-0? I would say the winner is still much better.
