The last match of the opening evening pits Madison Keys against Alison Riske. It’s now 4.15 BST, very tiring to stay up all night for these matches so why not get a wake-up call from your favourite player instead?

KEYS 4-6 7-6 6-2 RISKE: GAME, SET, MATCH! An ace is the ideal way to start any game but then that old friend the unforced error creeps in.

But she then throws it away again with a backhand that goes wide as Riske levels at 4-4 before Keys dumps a forehand into the net. Riske has two serves for a place in the second round but fearless hitting from Keys gets her level before Riske hits an easy volley long. Keys blazes a winner and from nowhere she pinches the set!
