Must do better!

15-0 - the Brit's eighth point won from nine successful first serves. That is impressive.
*Konta 5-2 Cirstea
Taken this time with a single-handed forehand winner a few feet inside the baseline. It was one of those low crouched efforts again.
Hold and the first set is yours Jo.
Konta 4-2 Cirstea*
The Romanian goes for calculated pot luck again with a forehand and this time it lands before the out of bounds.
Konta then strikes back with a tremendous winner of her own.
Break point two.
Konta 4-2 Cirstea*
Deuce as Cirstea continues her tactic of hitting the ball as hard as possible, which at this stage has resulted in more errors than winners.
Change of tactic?
Another mistake and it's break point Konta!

Konta knows if she maintains her level that her game is too good for Cirstea.
She does have to be wary of Cirstea having one of her purple patches but she looks full of confidence and it is just a matter of how she executes her shots.
All the early signs are that it's there today and she will boss Cirstea around.
*Konta 3-2 Cirstea
The 29-year-old breaks again to go a break up once again.
It's going to be one of those matches eh?

Cirstea is focusing on Konta's forehand now and trying to put some pressure on to make it break down a little.
If Cirstea gets any chance you know what she's going to do - she's going to wallop it!
Konta 2-2 Cirstea*
That didn't look like it was coming, but it did.
Cirstea produces a fabulous angled forehand winner which Konta cannot reach - even if her racquet head was twice the size.
*Konta 2-1 Cirstea
Another mistake from the Brit, who finds the net from the baseline.
15-40.

Hope?

15s each.
