Isner and Mahut's record-breaking match
John Isner and Nicolas Mahut's epic match on Court 18 is the greatest advertisement we've ever had for our sport beyond the spectacle of a Wimbledon final like Roger Federer versus Rafa Nadal.
I'm so proud, I must say, to be part of this great game and see those guys perform physically.
We don't get enough respect at times and our respect level is going to go way up because of this.
I am looking at Mahut, thinking he has played the entire day and the match has taken 10 hours, and he looks like he's in the second or third set.
I'm amazed those guys are still standing.
Isner looks like he's ready to fall, he's completely done and yet he still had the will to keep this thing going.
I would love to see the game resume on Centre Court on Thursday.
It would be a sign of respect for the two of them to get out there and have a moment that the entire stadium would appreciate before Andy Murray plays.
The balance of power now sits with Mahut because he seems physically fresher.
John is running on fumes but he is also able, at his height, just to arm it and win points on his serve.
Perhaps one of the guys might not even be able to play.
They are unbelievably conditioned mentally and physically but this is going to take six months out of their careers.
Mahut and Isner discuss 'fantastic' match
I have got a feeling that they may eventually change the rules now - they should do.
This is great and wonderful, they have broken every record there is to break but there should be a limit.
I would do it at six-all in the fifth and decide on the tie-breaker because you have to win that by two.
But this is amazing for our sport.
