Returning to thunderous applause, John Isner and Nicolas Mahut are now back on Court 18, and have begun to warm-up.
Isner definitely looks like the springier of the two.
The balls that will be used at the beginning of the resumption are the same they used in the latest stages of yesterday’s play, with the balls being kept in a refrigerator overnight to preserve their wear. The two are warming up with used balls, to simulate the ones they will be using to open this match.
Isner will serve first.
