Who do you think are the two most evenly matched players

[AAUS]

I guess you cant say it anymore but Agassi and Hewitt are probably the two closest that I can think of. Whenever they played they had close matches and there really never was a definite favorite at the start of the match. Their career head to head is 4 / 4 with their most onesided match going to hewitt at the masters cup in 2001 6-3, 6-4
