*Dart 6-4 0-3 Pegula
Jessica Pegula pops a neat backhand drop shot over the net to polish off a dominant hold to love.
Harriet Dart had successfully challenged a call after her forehand was deemed to have strayed beyond the baseline at 40-0, but it didn't impact the outcome of the game.
Pegula very much on top at the moment.

Having dominated the first set, Harriet Dart's level has dropped at the start of the second. A loose service game, featuring errant groundstrokes and ending with a double fault, gave Jessica Pegula a break and the American seems to be growing in confidence as she holds to love to back it up.
Boulter 3-6 7-6 (7-4) 2-2 Pliskova*
Boulter takes the opening point of her service game before using the slice to great effect to lead 30-0.
Pliskova hits her return from Boulter's serve into the net and then again at 40-15 as Boulter holds.
We are flying through these games in this set with both players serving strongly.
Dart 6-4 0-2 Pegula*
So, an impressive opening set from Harriet Dart against eighth seed Jessica Pegula, but the American has gained the upper-hand early in the second with a break in the second game.
Big boost for Pegula.
Broady 6-2 4-6 0-6 Schwartzman*
Things have unravelled rather quickly here for Liam Broady.
Diego Schwartzman rattles through a fourth consecutive break of serve to claim the third set in just 27 minutes.
*Boulter 3-6 7-6 (7-4) 1-2 Pliskova
Excellent stuff against from Pliskova as she holds to love, sealing the game with an ace - her 10th of the game.
*Broady 6-2 4-6 0-5 Schwartzman
A perfect illustration of the way things have started to go against Liam Broady.
He's convinced a Schwartzman groundstroke is long...
Image source, BBC SportTalk about fine margins. Ouch. That millimetre gives Schwartzman a 5-0 third-set lead. Broady serving to avoid a bagel in set three.
Boulter 3-6 7-6 (7-4) 1-1 Pliskova*
And Boulter responds with a superb service game as she holds comfortably. Some great tennis being played by both today, nothing between them.

Whether you like the roof or not, there is no doubting it creates an awesome atmosphere.
The decibel-meter sharply surges north as Boulter levels the match.
Goosebump-inducing stuff.
The Brit's nearest and dearest ecstatically leap to their feet - with her parents and brother jubilantly hugging each other.
Her good friend Jodie Burrage, who lost in the first round of the singles, is also those grinning a wide grin.
*Boulter 3-6 7-6 (7-4) 0-1 Pliskova
The opening game of this third set goes with serve as Pliskova holds.
Boulter has gone toe-to-toe with last year's finalists and will be fancying her chances of another win against her opponent in the space of a week.
Dart 6-4 Pegula*
Alan Jewell
BBC Sport at Wimbledon
Over on court two, Harriet Dart is very much the underdog against American eighth seed Jessica Pegula but you wouldn't know it so far.
Dart has been the player making all the running and has just held to love to win the first set.
Dart 6-4 Pegula
Perfect start for Harriet Dart on Court Two as she wins the first set of her second-round tie with Jessica Pegula 6-4.
Broady 6-2 4-6 0-4 Schwartzman*
Liam Broady is broken for the third service game on the spin.
He was winning his fair share of the hard-fought rallies in sets one and two - but Schwartzman is prevailing in almost all of them right now.
Boulter 3-6 7-6 (7-4) Pliskova*
Anne Keothavong
Former British number one on BBC TV
Boulter did a great job to hold her nerve, cut back in a few of those errors in the first set but Pliskova really hurt by errors and double faults at crucial times in that second set.
Boulter has the momentum and the crowd support, ands she is absolutely loving it out here.
Boulter 3-6 6-6 (7-4) Pliskova
Boulter fends off a Pliskova fight back before producing some brilliant serves to win the tie-break and we head into a third set.
Boulter fist bumps the air and the crowd roar in delight.
Boulter 3-6 6-6 (4-0) Pliskova
Brilliant stuff from Boulter as she races into a 4-0 lead, superbly getting to the net to save a point before forcing Pliskova to send a return wide.
The crowd are revved up and Boulter is on the verge of taking this to a third set.
Broady 6-2 4-6 0-2 Schwartzman*
This is an absolutely compelling match the Court Three crowd are being treated to. Mesmerising stuff with fantastic rally after fantastic rally.
But things are starting to go ever so slightly awry for Liam Broady.
He's not actually doing a lot wrong but his level has just dipped a tad while Diego Schwartzman's game has improved noticeably - and the 12th seed gets the first break of set three.
*Boulter 3-6 6-6 Pliskova
Another strong service game by Pliskova as she holds to love and we go to a tie-break.
Boulter 3-6 6-5 Pliskova*
David Law
Commentator on BBC Radio 5 Live
Katie Boulter has guaranteed herself at least a tie-break after that, but she has loftier ambitions than these.

Katie is looking like she still believes she can win this and she's looking over at her box a lot for a little extra encouragement.
