Konta 6-2 6-7 (5-7) 4-5 Cirstea*
So Sorana Cirstea... how are the nerves?

With her back to the wall, Konta really upped her aggression on the serve. Her first and second serves were in much more effective spots.
Konta 6-2 6-7 (5-7) 4-5 Cirstea*
A brilliant second serve from Konta and it's advantage before the Brit pulls out another great serve down the middle.
Stunning from Konta.
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
Another saved with an ace down the T.
Amazing!
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
One match point saved as Cirstea goes long.
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
That hope looks more faint as Konta finds the net.
The final curtain? Two match points...
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
15-30 as Cirstea chases down another drop but this time finds the net with her attempted return.
Hope for the Brit.
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
Cirstea steps inside for Konta's second serve and puts the pressure on the Brit who goes long from the back.
0-30.

I love this for a level of tennis from 0-40. Extraordinary stuff from Cirstea, on the front foot, inside the baseline and just thumping winners.
What a transformation because at the beginning of this match we thought Konta would do everything better Cirstea. They have got similar styles.
I wasn't expecting this level from the Romanian and not expecting her to sustain it if we got a patch of it.
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
A long rally ends with Konta's forehand drifting wide.
0-15.
Konta 6-2 6-7 (5-7) 3-5 Cirstea*
A second serve for Cirstea but Konta's return is just that wee bit too long.
A huge moment in the match.
Konta 6-2 6-7 (5-7) 3-4 Cirstea*
Remarkable! Cirstea saves the third after a deep shot to the feet to Konta is too good to return.
Deuce.
Advantage for the Romanian.
Konta 6-2 6-7 (5-7) 3-4 Cirstea*
One break point saved with a winner down the line - but Cirstea really had to stretch.
Another saved after a brave approach to the net.
Konta 6-2 6-7 (5-7) 3-4 Cirstea*
0-30.
0-40 as Cirstea's tired forehand shot is wide.
Konta 6-2 6-7 (5-7) 3-4 Cirstea*
Good start - a double fault.
0-15.

Wow. That's going to hurt for Konta, the way Cirstea was able to break.
What a huge dig from Cirstea, she loves chasing down drop-shots, Great hands skills from her and brilliantly-executed.
Konta didn't do much wrong, it is just the kind of play Cirstea likes.
Konta 6-2 6-7 (5-7) 3-4 Cirstea*
She's only gone and done it!!!!
But my, she chased that drop down and produced a glorious angled pick-up shot for the break.
She'll probably get broken back now.
*Konta 6-2 6-7 (5-7) 3-3 Cirstea
Cirstea loops her return well wide of the tram lines.
Guess what? Another break-point chance for the Romanian...
*Konta 6-2 6-7 (5-7) 3-3 Cirstea
Cirstea goes for Hollywood again off Konta's second serve - this time her thumping double-hander delivers.
She then sets up another break point chance!!!
