Andre Agassi, in his last game before retirement, vs. James Blake, No. 1 in the United States.

And they fought to the bitter, tiebreaking end; tonight, they both had their first fifth-set tiebreakers, and the crowd was standing up for the majority of the time, cheering them both on (chants of “Andre! Andre!” and “Blake! Blake!” rang throughout the auditorium without ceasing).

Agassi won, but at the very last match point (#2).

I quote the USA Network commentators’ memorable statements within the last 5 minutes of the match:

Commentator A: “Does anyone have to lose?”
Commentator B: “I hope not.”
