It is a weapon, the forehand of Katie Boulter. She is not going away!
Boulter 6-0 4-6 3-3 Makarova*
Another break point for Katie Boulter - can she take it at the third attempt?
Nope. Ekaterina Makarova's scuttling and scrambling as if her life depends on it.

What I particularly like about Katie Boulter is her attitude. She’s a feisty one.
The 22-year-old from Leicester always has a steely look in her eyes and is able to brush off mistakes quickly.
Not bad to traits to have...
After framing a forehand out of the court - maybe hitting someone’s bonce in court 13 next door - she recovers with a blistering winner.
Boulter 6-0 4-6 3-3 Makarova*
Katie Boulter skips in to meet a short ball from her opponent, but can only clip it wide from a narrow angle.
The Brit brings up deuce again with a thundering forehand - now just to string a couple of points together...
Boulter 6-0 4-6 3-3 Makarova*
Good hustle from Ekaterina Makerova to stave off a second break point during this service game, but she's being made to work for it.
Good first serve from the Russian, but then she's wrong-footed by an energetic Boulter.
Boulter 6-0 4-6 3-3 Makarova*
Gahhh, Katie Boulter's not happy with that - the break point slips away for a moment.
She'll get another chance, leaping into a thumping forehand winner from height.

Good pressure there from Boulter, hitting that forehand with a lot of pace and moving forward to the net.

Katie Boulter's sticking around on the Ekaterina Makarova serve, and then leaps on a short second serve to hammer it back with aplomb.
Break point chance.
Boulter 6-0 4-6 3-3 Makarova*
Good depth from Katie Boulter, a forehand winner into the space vacated by Makarova to ease the pressure on her service game at 30-30.
The Russian goes wide, but she's challenging... nope, that's definitely wide.
Boulter tidies up with a passing backhand winner to hold.
*Boulter 6-0 4-6 2-3 Makarova
Back on serve... can Katie Boulter level up?
A little fist pump from the world number 99 as she rattles to 15-0, but Ekaterina Makarova soon turns it around with some fiery returns.

Plenty of British accents are giving encouragement to Katie Boulter - including Fed Cup captain Anne Keothavong.
That framed serve, which dinged the scoreboard behind Makarova’s baseline, met with stunned silence.
But that all changes when Boulter breaks back. A huge roar greets the winning point, followed by a rousing ‘Let’s go Katie, let’s go!”
This tight court, on the edge of Melbourne Park with the skyscrapers of the Central Business District in the background, is pretty rammed.
*Boulter 6-0 4-6 2-3 Makarova
And Boulter breaks back!
Cracking response from the 22-year-old.
Boulter 6-0 4-6 1-3 Makarova*

Double fault from Katie Boulter.

*Boulter 6-0 4-6 1-2 Makarova
Aggressive tennis from Katie Boulter, sprinting towards the net to take the point to Ekaterina Makarova and tying the Russian up in knots.
Boulter slides into a backhand that kisses the tape and drops the wrong side for the Brit - a punchy first serve makes it 30-30, but that's a loose backhand and Makarova has a break point.
*Boulter 6-0 4-6 1-2 Makarova
Good scrambling from the world number 57, bringing it back to 30-30.

Sweet forehand from Katie Boulter as she steps on to the front foot to get Ekaterina Makarova sprawling.

Boulter holds.
*Boulter 6-0 4-6 0-1 Makarova
And so to Katie Boulter, who is one set apiece with Ekaterina Makarova.
Cheers for the world number 99 as she rattles to a 30-0 lead on serve, only to hammer a straightforward backhand into the net from mid-court.
