Welcome to our LIVE coverage of Caroline Wozniacki v Daria Kasatkina.

GAME, SET AND MATCH! - KASATKINA 7-6 6-3 WOZNIACKI. The young Russian makes it three games in a row as she serve it out to 15 to book her spot in the last eight. The world No.2 is OUT. It was an intriguing affair lasting one hour and 57 minutes that included the overnight delay - but there's no doubt Kasatkina deserved it.

BREAK! - KASATKINA 7-6 5-3 WOZNIACKI. The Russian breaks! Wozzy saved two separate BPs, but was again beaten in the baseline game of chess on a third. It was the longest point of the match and could well mean curtains for the world number two. Daria will now serve for the match.

KASATKINA 7-6 4-3 WOZNIACKI. Daria outlasts and outsmarts Wozzy with some more probing tennis to edge the opening game following the overnight delay to 30.

Welcome back! It's the second Monday at the 2018 French Open and after Simona Halep's demolition of Elise Mertens, Wozniacki and Kasatkina are due back on Chatrier shortly to conclude their round four clash.

And that's it for the evening. Play suspended. See you tomorrow.

KASATKINA 7-6 3-3 WOZNIACKI: Kasatkina is coming into the net and making so many problems for herself, leaving herself stranded and allowing Wozniacki all the space she wants.

KASATKINA 7-6 3-2 WOZNIACKI: Slightly unfortunate for Wozniacki, a couple of wayward shots which she really should have controlled better and given her the break.

KASATKINA 7-6 2-2 WOZNIACKI: A bit of nous and knowledge from Wozniacki, holding serve in the face of low-flying pigeons.

KASATKINA 7-6 2-1 WOZNIACKI: Kasatkina will be happy that they're carrying on for the time being, and the pair sit down as the umpire calls for new balls.

They're going to play on.

Looks like the referee has been called.

The crowd is slow-clapping as the players talk to supervisor Pam Whytcross.

The duo exchange a little smile as they discuss the light status.

Both players have gone across to the umpire as the clock ticks past 9pm Paris time.

KASATKINA 7-6 1-1 WOZNIACKI: Kasatkina is raging with herself, letting a 30-0 advantage slide.

KASATKINA 7-6 1-0 WOZNIACKI: Some wonderful ball striking from Daria Kasatkina, who's equalling Wozniacki in both good and bad ways - pretty much the same points on first serve and the same number of unforced errors.

KASATKINA 7-6 WOZNIACKI: Wozniacki throws this away, offering a return so limp she dropped her racket - from a serve so slow the ball failed to register on the speed radar.
