Hants 400-9d v Northants 124-5
A superb morning for Hampshire.
They found it tough going yesterday afternoon with just one wicket but have found four in the first session of day three.
Northants gave them two cheap ones but often this relentless attack and draw errors.
Huge task for the visitors to try and get back in the game - still another 127 needed to avoid the follow-on.
Somerset 248 v Gloucs 343 & 49-1 lead by 144
Maiden over from Sajid Khan.
Somerset are putting the brakes on this innings. 21 runs scored off the last 10 overs.
Just one run off Aldridge at the other end and that's lunch. A solid session of play for Gloucestershire overall, but how important will those 69 runs from the last two Somerset wickets be?

India opener Gill, on debut, reached a calm maiden Championship fifty off 87 balls with six fours and a six, though Worcestershire cut off his boundary shots as his knock continued.

Yorkshire have their first batting point, by the way.
