BBC Coventry & Warwickshire's Clive Eakin at Edgbaston:
"Having been recalled to the Test squad Nottinghamshire James Taylor has been enhancing his case for a starting place in England's matches against Pakistan by scoring an unbeaten century.
"He's taken advantage of some good fortune, having been dropped three times, to lift his team out of trouble and reach 114 not out.
"Notts lost just one wicket between lunch and tea, that of Samit Patel for nine, bowled round his legs by Keith Barker, who has four wickets."
Durham recover after triple setback
Worcestershire 350-7 dec, Durham 183-5 - tea, day three
BBC Newcastle's Martin Emmerson at Chester-le-Street:
"Worcestershire declared after picking up a fourth batting point and are trying to move the game along following the loss of a day.
"Durham put 83 on the board for their first wicket, which is their third best start this season, but they were 88-3 just five overs later as Jack Burnham (21), Mark Stoneman (52) and Paul Collingwood (2) all fell.
"Scott Borthwick will resume after tea on 51, having reached his 10th half-century of the campaign."
Debutant strikes for Glamorgan
Glamorgan 233, Northants 128-5 - tea, day three
BBC Radio Wales Sport's Nick Webb at Wantage Road:
"The bowlers continue to hold the upper hand on day three at Northampton with Dewi Penrhyn Jones and acting captain Graham Wagg claiming two wickets each for Glamorgan.
"Alex Wakely has top-scored so far with 40, but with bad light intervening again, Wakely and Wagg will need to reach agreement on a final-day chase to give much hope of a positive result."
Rain frustrates Hampshire
Hampshire 400-9 dec, Yorkshire 97-4
Hampshire's hopes of victory of Yorkshire to boost their chances of avoiding relegation were dented by rain on the third day at the Ageas Bowl.
Only 7.4 overs were possible before bad light, and then rain, arrived and umpires Tim Robinson and Peter Hartley called things off for the day at 14:30 BST.
Surrey in charge at old Trafford
Surrey 480, Lancashire 272 - lunch, day three
Lancashire conceded a first-innings deficit of 208 as brothers Sam and Tom Curran helped Surrey bowl them out on the third morning at Old Trafford.
Seventeen-year-old Sam took 5-67 and elder brother Tom, 20, claimed 3-54 as the Red Rose county added 131 to their overnight 141-5.
Ashwell Prince, who retired at the end of the season, top-scored with 45.
Play begins on day three at Grace Road
Leicestershire 117-2 v Essex - lunch, day three
Leicestershire and Essex finally began their match at Grace Road after two washout days.
An unbroken partnership of 90 between Angus Robson and skipper Mark Cosgrove has taken the Foxes, who are likely to finish bottom of the table for the third year running, to 117-2.
They have won just two games so far and need a victory over Essex to keep alive their hopes of avoiding finishing last again.
Lloyd misses out on century
Glamorgan 233, Northants 52-2 - lunch, day three
BBC Radio Northampton's Alex Winter at Wantage Road:
"It's taken three days but we have finally had an uninterrupted session.
"Glamorgan's David Lloyd was moving towards a maiden first-class hundred before falling to a stunning catch in the deep for 92.
"That special moment didn't happen, but another did when Dewi Penrhyn Jones, on first-class debut, had Ben Duckett caught behind to the last ball of the session for his maiden wicket."
Taylor rides his luck
Nottinghamshire 105-4 v Warwickshire - lunch, day three
BBC Coventry & Warwickshire's Clive Eakin at Edgbaston:
"With play finally under way after just four overs were bowled on the first two days, Notts batsman James Taylor has taken advantage of the first lengthy spell of play to celebrate his England Test squad recall with an unbeaten 53.
"He has been dropped three times, including once off a no-ball but has continued to bat positively, but Alex Hales went for just six.
"For Warwickshire Keith Barker, produced an excellent spell of bowling to take three wickets and Jonathan Trott claimed his first of the season just before lunch."
Rain hits south coast fixtures
With rain across the south-east coast on Wednesday morning there has been no play for the second day running at Canterbury, where Kent and Gloucestershire have managed only 15 overs in the opening three days.
Further west at Hove there has also been disruption, with no play before lunch between Sussex and Somerset.
And across at Southampton only 7.4 overs were possible in the morning session between Hampshire and Yorkshire.
Worcs secure fourth batting bonus point
Worcestershire 350-7d; Durham 40-0 - lunch, day three
BBC Radio Newcastle's Martin Emmerson at Chester-le-Street:
Bottom club Worcestershire have done their bit to try and make up for the lost day on Tuesday.
Ross Whiteley and Tom Kohler-Cadmore put together a quick-fire partnership of 90 for the fifth wicket, which ended when Whiteley was bowled by Ryan Pringle for 51. Kohler-Cadmore went on to make 89 before he was stumped off Scott Borthwick.
And having reached their fourth batting point Worcestershire then promptly declared on 350-7 to leave them with eight overs to bowl at Durham before lunch. Durham survived and are 40-0.
