6:16pm - It's stumps at all three of our games and here is the state of play:
Warwickshire are 254 for six, with Laurie Evans 85 not out, after choosing to bat against Nottinghamshire at Edgbaston.
Glamorgan are 315 for three, with Murray Goodwin and Jim Allenby unbeaten on 138 and 68 respectively, against Lancashire at Emirates Old Trafford.
Hampshire are 262 for three, with Michael Carberry still there on 137, against Kent at Canterbury.
5:45pm - It's been quite a day for Glamorgan, who pass 300 for the loss of just three wickets as Allenby and Goodwin prosper.
5:10pm - Hampshire lose another when James Vince is pinned in front by Calum Haggett, only for Michael Carberry to raise the visiting fans' mood by reaching a fine century. Glamorgan roll on versus Lancashire, meanwhile, as the in-form Jim Allenby moves past 50.
Warwickshire are enjoying no such happiness with the bat, Rikki Clarke the latest man to go as Adams strikes once more.
4:49pm - A couple of wickets to update you on: Hampshire have lost Liam Dawson, trapped lbw by the ever-impressive Darren Stevens for 75, while Chris Woakes managed just 14 for Warwickshire before being bowled by Samit Patel.
4:30pm - Murray Goodwin has rediscovered his best form in recent times, epitomised by the veteran reaching yet another century. Elsewhere, Andre Adams has had Tim Ambrose caught behind to leave Warwickshire four down.
4:10pm - The action has resumed at the start of the evening session.
3:49pm - The interval arrives in the other two games with Warwickshire 186 for three and Evans on 50 while Hampshire are 171 for one with Carberry and Dawson, who have put on 140, on 84 and 72 respectively.
3:41pm - It’s tea at Emirates Old Trafford where Glamorgan are 201 for three and Goodwin is on 80.
3:21pm - Westwood’s vigil ends on 68 as he drives Samit Patel to mid-on, making Warwickshire 132 for three. He added 89 with Laurie Evans.
Simon Kerrigan has his second victim of the day, Chris Cooke for 23. That leaves Glamorgan 185 for three and halts a stand of 65 with Goodwin, who is still going strong.
3pm - Carberry shortly follows Dawson to a half-century as they approach a century alliance.
2:36pm - Murray Goodwin continues Glamorgan’s good progress by bringing up a fifty.
Westwood has been dropped by Alex Hales at second slip.
2:19pm - Ian Westwood heralds a patient half-century for Warwickshire. Meanwhile, Michael Carberry and Liam Dawson have shared a fifty partnership for Hampshire’s second wicket.
What a catch! Agathangelou takes the catch (bowled Hogg) at the second time of asking at 2nd slip and Rees goes for 58. Glamorgan 120-2.
