And with the night sky getting a touch gloomier, the umpires order the players off again at The Oval after that mini session.
There's still 10 more overs scheduled to be bowled this evening, but we may well have seen the last of the action until the morning.
We'll wait and see though...
Post update
Glamorgan 193-9 v Warks 186
Late wicket for Warwickshire as skipper Will Rhodes bowls Lukas Carey for 23.
Glamorgan number 11 Michael Hogan comes in, his side are seven away from a batting point, his partner is 10 off a half-century and there are 27 balls until the close.
So what does Hogan do?
Swing and a miss.
Surrey lose two more in two balls
Surrey (170-4) trail Sussex (415) by 245 runs
Oh dear! Surrey will be fuming now that they had to come back out and face more bowling in the south London gloom.
Rory Burns went first ball back to Jack Carson and now Henry Crocombe at the other end has taken two wickets in two balls for Sussex.
First he bowled Jamie Smith after he offered no stroke to one that nipped back and then he trapped nightwatchman Adam Finch leg before first ball.
Ben Foakes narrowly survives the hat-trick ball as he digs out an inswinging yorker!
Scores level at Cardiff

Stumps at New Road
Worcestershire (200) trail Somerset (251 &16-1) by 67 runs
The light doesn't improve and that'll be close of play.

Close of play at Canterbury
Kent (170) trail Hampshire (191 & 108-5) by 129 runs

Hampshire will finish it the happier you feel after they were right up against it at one stage in this second innings at just 23-5.
Lewis McManus (50 not out) and Tom Scriven (42 not out) have rescued them from the mire and may well have compiled a match-winning partnership worth 85.
