Big serve and it's tie-break o'clock.
Konta has already won one of these in this tournament.
*Konta 6-2 5-6 Cirstea
Cirstea gives away another point with an error down the line - she's arguing with herself.

This is the highest level I've ever seen from Cirstea.
This is big-hitting baseline tennis, and real quality.
*Konta 6-2 5-6 Cirstea
This time the Romanian does hold and passes the pressure back on to the racquet of Konta.
Konta 6-2 5-5 Cirstea*
Another big serve and it's advantage v the ninth seed.
Konta takes a huge risk by coming to the net, luckily for her Cirstea lets herself down.
Deuce no.5.
Advantage Cirstea again.
Konta 6-2 5-5 Cirstea*
Cirstea sprints to the net like her life depended on it...or a break. The effort pays off as she swipes the 'A' sign off the board.
Deuce.
Advantage.
Deuce with an ace.
Konta 6-2 5-5 Cirstea*
Advantage Konta as Cirstea smacks the net from the back.
Hmm...

Cirstea has definitely made a marked change to go down the line on her forehand. It has been effective too.
Konta 6-2 5-5 Cirstea*
Cirstea sends Konta deep before approaching the net and slapping down a winner.
40-30.
Deuce.
Konta 6-2 5-5 Cirstea*
15s each.
Cirstea then opens up her body and lets rip with a forehand which actually has the desired effect.
30-15.
30-30.
Konta 6-2 5-5 Cirstea*
Cirstea, bored of not having a sniff of a point, holds down the B button for too long from Konta's first serve.
Game.
*Konta 6-2 4-5 Cirstea
The British number one needs these first serves to land in.
15-0.
30-0.
Then another sends Cirstea to her right before Konta lands the Povetkin punch.
40-0.
*Konta 6-2 4-5 Cirstea
A glorious one-handed forehand lands a fifth of a tennis ball in for Cirstea.
Thank goodness for tech.
Time to break Sorana?
Konta 6-2 4-4 Cirstea*
Saved by Konta with two double-handed crosscourts before a winner down the line. Boxing clever.
Deuce.
Advantage Cirstea.
We've been here before.

We haven't seen a lot of aggressive down-the-line shots from Cirstea. She's not been able to do it because of the pressure from Konta, who has neutralised that weapon by moving her out wide.
Konta 6-2 4-4 Cirstea*
The Brit stays in the rally before she crouches down going for backhand glory but finds the netting.
Deuce.
Advantage Cirstea.
Konta 6-2 4-4 Cirstea*
Break point saved before Konta sets up another with a flat angled forehand that dips just inside the trams.
Konta 6-2 4-4 Cirstea*
The umpire has a time-violation word with Cirstea - another and she will be docked a first serve.
30-30.
30-40 as the Romanian's serve goes for a trip to New Jersey.
