Answer 1

This match I am watching now must be the Highest. So far ....39/38. Hahut (France)

Isner )(USA) Wimbledon 23 June 2010

Update: In the 5th set the score is now 53-54 Hahut - Isner...on serve!!

9 hours and 25 minutes into the fifth set of a second round Wimbleton match between N. Mahut and J. Isner. 54 -55 on serve!!

10 hours in, the game has been called due to darkness with the score tied at 59 each in the fifth set. This match has set records for most games, sets and aces in a match!! To be continued tomorrow June 24th, 2010!!

Answer 2

The fifth set score can go on indefinitely, but the other four sets will end up at 7-6 at the max.

The largest score ever achieved at Wimbledon in the fifth set alone was an astounding 70-68 score, played by John Isner and Nicolas Mahut, respectively.

Answer 3

Puss Sampras
