The American leads the defending champion!

This set was oh so tight but in five quick minutes, McCartney Kessler has wrestled control.

The break points tell a story. Kessler converted two of five. Boulter managed just one of 11.

"Come on!" and "Yeah!" shouts Draper after taking two big points to lead 30-15. He's looking to get the first break of this second set...

Kessler gets exposed at the net, but Boulter can't punish her, slamming a forehand into the net.

40-0.

Anything you can do, I can do better as Draper also holds to love, firing off a couple of aces - including a 120mph one on his second serve - to get the job done.

American McCartney Kessler breaks to love after Boulter slaps a forehand wide.

Boulter's shoulders drop. The world number 42 will serve for the set.

Back-to-back double faults from Boulter spells trouble.

0-40, right at the end of this first set.

It is feeling like Nakashima is really getting into his groove now as he races through his serve to love hold.

Fairly routine holds at the moment in Nottingham.

New balls are on the way as we approach the business end of the opening set.

Those strong serves continue and Draper seals the hold as we approach the two-hour mark in this tight match.

The crowd are doing their best to will Draper to get the win and the support helps as two thumping first serves seal the opening two points of this game.

Far more standard hold from Boulter, her first without facing a break point.

Hold to 15.

Pick a winner?...It's impossible at the minute. There is just so little in it.

A couple of nice winners in that game by Draper including a forehand down the line, but it isn't enough to prevent Nakashima sealing the hold.

Impossible to call which way this will go.

We are starting to see a little bit more aggression from Draper.

More great hitting from McCartney Kessler who gets pace from the back of the court.

She manages to sneak to a hold to retake the lead and stop Boulter's two-game winning run.

You don't hear much from Nakashima during matches so it is hard to gauge how he is feeling. Draper is far more vocal as he tries to motivate himself, particularly as mistakes creep in on his serve.

He gets the hold, though, as Nakashima plants a forehand into the net.

Katie Boulter is running miles and miles already in the sun today, chasing down lost causes, but somehow getting the ball back into play.

Her sprints are rewarded as she sets up a couple of break points, but each time Kessler responds with strong first serves.

Deuce.

That was a beautiful shot. It was a big point to score and he made it look easy.

Nakashima does well with an awkward bounce to send it down the line and out of Draper's reach to halt a bit of the latter's momentum after a couple of winners. Nakashima then seals the hold with an ace.
