Makarova is completely confused, guessing on every serve and can barely get a racket on it. Even off the ground she is trying to change it up and be more aggressive but Konta just has an answer for everything.

Shot! That's lovely from the Brit, down on one knee and leathering a forehand winner. Makarova then responds with one of her own down the line.

Ooft. That's empthatic from Konta, a hammered backhand that beats a diving Makarova.
Two break points for Konta as a floaty backhand from Makarova goes long, and then another slam from the Brit, right into the corner, gives her the early break. There's a fist pump and a shout of "come on!"

Makaraova hits the ball a lot flatter than someone like Wozniacki in the previous round, which could be advantageous for her as Wozniacki’s ball sat up a little for Konta to attack. The other way Makarova can really hurt Konta is the angles she can create by hitting it flat off the court.
Konta 1-0 Makarova*
Konta's starting as she means to go on, giving Makarova the run around before coming up to the net and tapping a backhand over.
Her serve is quick too and that's a straightforward hold for the Brit.

Konta and Makarova are out and warming up. Warming up isn't the right word - it is roasting out there. Just the 34 degrees for the players to contend with today.
Konta will serve first up.
Williams 7-5 6-4 Strycova
Konta's potential opponent in the last eight will be one Serena Williams.
The world number two won an entertaining first set against Czech Barbora Strycova 7-5, despite dropping her serve three times.
It wasn't straightforward but she's take the second set 6-4 to secure her place.
Williams will also regain the number one ranking if she wins the title in Melbourne, after Angelique Kerber's exit yesterday.
