First set: Halep* 5-5 Muguruza (* denotes server) The sign of a champion player? She needed to break and Halep does just that. Muguruza doesn’t help herself, hitting the net at 0-30 down to give the Romanian three chances. She needs just the one, after a rally featuring two net cords, which make life a bit tricky for the Spaniard. Nothing to separate these two in terms of the scoreboard at the moment. 6.06am GMT
First set: Halep* 4-5 Muguruza (* denotes server) Faced with having to win this game to stay in the first set, Halep rises to the occasion perfectly. A stunning backhand winner to go 30-0 ahead highlights what turns out to be a love service game. But she’ll now have to break Muguruza now if she’s to stay alive.
