Sramkova sinks to her knees as she sends a shot into the net to hand Raducanu an immediate break.

All that hard work to fight back in the first set and she will now be sensing deja vu from the start of the match.

Sramkova is looking frustrated again as she overhits a couple of returns and Raducanu is up 30-0. A good forehand has too much for Raducanu but the soon-to-be British number one takes the next point and has two break points...

From 5-0 up and two set points up there was just a slight wobble from Emma.

Her opponent opened her shoulders up and went for broke. It paid off for a few games. But it was good to see Emma restore some confidence by holding serve to love.
