Adam Lyth with his medium-pace off-spin has done the golden arm act again.

Yorkshire are keeping themselves in this with just a little bit of a sniff.

Don't go away, we have got a very interesting final session of this match in prospect and maybe, just maybe Sam Northeast and a bit of assistance from one or two of his lower order team mates standing between Yorkshire and a win.

Lancashire will take a little comfort from the way they fought back in the match but this is Kent's victory because this has been a difficult place for anybody.

Nobody won a County Championship match here last season - every game was drawn. Lancashire haven't lost a County Championship match here for two years and to come and bowl Lancashire out twice and take 20 wickets is a fine effort.

The fact it's so rarely done in the last few seasons shows just how well Kent have performed across the four days.

A thoroughly deserved victory for Kent.

With rain ruining the final day at Lord's, Yorkshire need to force a Glamorgan collapse if we are to get a grandstand finish to round five.

Just one Division One game made it to day four, and that was wrapped up before lunch as Kent eased to a first win of the season at Old Trafford.

A brilliant skipper's knock of 79 not out from Daniel Bell-Drummond sent them back to the south east in celebratory mood.
