Hello and welcome to ladies' quarter final day at Wimbledon 2018. It promises to be an intriguing afternoon of tennis as it is the first time since seedings were introduced in 1927 that none of the top eight women on the tour have made it to the last eight.

BREAK! GAME, SET AND MATCH! - KERBER 6-3 7-5 KASATKINA. That is one of the best concluding games of a match you're likely to see. Kasatkina plays some sensational shots, including a crosscourt dropshot to stave off one of six match points, but she can't thwart Kerber on the seventh and the German moves in to the last four to meet Ostapenko after one hour and 28 minutes.

BREAK! - KERBER 6-3 6-5 KASATKINA. A massive roar of delight from Angie. No understated celebration this time. She breaks again and has another chance to serve this match out.

Del Potro books a last eight showdown with Nadal after seeing off Simon in four sets.

BREAK! - KERBER 6-3 5-5 KASATKINA. It's a disaster for Kerber. She's too conservative once again. A second ace of the match does little to help from 0-30 and Kasatkina breaks back to stay in contention. Kerber may yet look back at that game in dismay.

BREAK! - KERBER 6-3 5-4 KASATKINA. It's an understated pumping of the fist from Kerber as she finds a second wind and breaks again with a deep crosscourt forehand that's just too good. She will now serve for the match.

BREAK! - KERBER 6-3 4-4 KASATKINA. It's a shocker from Kerber, but some wonderful shot selection and angle on the forehand attack from Kasatkina. The German looks in control at 40-15 but inexplicably tenses up. Daria gets to deuce and piles on the pressure before breaking at the third attempt. All square.

Meanwhile, in the men's draw, the match still to finish after being suspended last night has also had some rollercoaster moments.

BREAK! - KERBER 6-3 4-3 KASATKINA. The Daria rollercoaster continues. The double faults have been a problem as have the unforced errors that are now clocking over 20 so far. Kerber breaks on her second opportunity and wrestles the momentum back her way.

BREAK! - KERBER 6-3 3-3 KASATKINA. Fist pumps all around. Kasatkina gets her mojo flowing and works her way to triple break point. Kerber fends off one, but it's too much to do and we are back on serve!

KERBER 6-3 3-2 KASATKINA. The Russian stays in touch. Can she find something special to turn the tide? She needs to cut out the occasional moments of sloppiness as Kerber almost hits back from 40-0 down but can't quite make it to deuce.

KERBER 6-3 3-1 KASATKINA. That is so solid from Kerber. She consolidates with a highly efficient hold to 15.

BREAK! - KERBER 6-3 2-1 KASATKINA. Oh dear. The No.14 seed endures more service woes. She's lacking the consistency that Kerber has in abundance. The Russian serves one break point, but Kerber won't let her wriggle free from deuce and the German is now firmly in the driving seat.

KERBER 6-3 1-1 KASATKINA. Daria hits an audacious tweener - but ends up losing the point, and the game to 30. The crowd are loving her. She may lose today, but there's no doubt she's a star-in-the-making.

KERBER 6-3 0-1 KASATKINA. An ace and a pair of winners help Kasatkina get the first game of Set 2 off to a brilliant start.

SET! - KERBER 6-3 KASATKINA. Daria drifts a backhand long and it sees Kerber take the set in 32 minutes. The Russian hit the point of the game with a sweeping crosscourt drive-volley, but it was all she could muster as the No.11 seed kept her cool to serve it out.

BREAK! - KERBER 5-3 KASATKINA. Just when it looked like Kerber was in for a dog fight for this set, Kasatkina gifts the German the break advantage once more. The double faults are again very costly and you fancy Angie will see out the opener from here.
