Somerset 329-6 v Hampshire - lunch

Is there a brighter prospect in English cricket than James Rew?
The 19-year-old only came into the Somerset side a year ago and already has six centuries to his name, including five this season.
His 132 not out is his highest first-class score and takes him to 863 runs for the season, but it is his composure as much as his skill which marks him out as a very special cricketer.
A word too about 22 year old Kasey Aldridge, who helped Rew add 188 for Somerset’s 6th wicket, a club record against Hampshire. He’s another bright prospect, and they’re both local Somerset boys. Ciders all round!

Can we play you every week? Rob Yates is too polite to mutter that over lunch, but he might be forgiven for thinking it, having raised his second century of the Championship season – both against Kent – five minutes before the interval.
It has been a patient effort, although at a slightly higher cadence today after three early boundaries. He may sense that his job is not done yet, with a second new ball - just four overs old - to help to see off.
It is possible that Glenn Maxwell may be the man to help soften the fresh Kookaburra a little more quickly than normal, the Australian making an unexpected appearance in the Championship following his stint in the T20 Blast.
There was no big score from the Big Show in the short competition, but his innings so far has suggested it might come today, with one ball already struck towards the top deck of the new flats.
Jack Leaning has been has made him the most successful Kent bowler so far. He lured Jacob Bethell and Ed Barnard into faulty strokes in the same over, and even allowed himself an over with the new ball. His efforts may help to limit Warwickshire’s lead, but the visitors are already 100 in front with considerable power to add.
