Hampshire completely dominated Warwickshire on the second day of their match at The Rose Bowl, thanks to a brilliant undefeated double-century by Shane Watson. Hampshire were 353 for 6 overnight, and added a further 223 runs without losing a wicket. Watson, 91 at stumps on day one, cruised to his century - his first of the season and ninth of his career - and combined brilliantly with Dimitri Mascarenhas, who also struck a century, in a partnership worth 234. Both were unbeaten, as Hampshire declared on an imposing 576 for 6. In reply, Warwickshire stumbled to 145 for 4: Nick Knight stabilised the innings with an unbeaten 97 as the visitors trail by as massive 431 runs.
On a rain-affected day at Cardiff, Nottinghamshire gained a lead of exactly 100 over Glamorgan but lost five wickets in the process. Younis Khan struck a fifty and Darren Bicknell, 81 not out overnight, went on to make his second hundred of the season. Bicknell was the first man to fall, dismissed by Dean Cosker, which spelt a collapse for Nottinghamshire who lost five for 20. Robert Croft took three of those to fall, as Notts ended the day on 251 for 7.
Ed Smith struck 70, and Ed Joyce was left unbeaten on 71 as Middlesex went to stumps on 238 for 6 against Gloucestershire. Smith, Ben Hutton and Owais Shah all fell to William Rudge who finished with 3 for 64 from 17 overs. Despite wickets tumbling all around him, Joyce was steadfast and patient, taking 166 balls to craft his 71 runs. Middlesex trail Gloucestershire by 95 runs, with four wickets left in hand.
Derbyshire slipped to 64 for 4 in their match against Durham at Chester-le-Street, before Chris Bassano and Australian Jon Moss both hit half-centuries in a stand worth 148. Liam Plunkett took 3 for 49, and Brad Williams 2 for 68. Derbyshire have a slender lead of 58, with Luke Sutton unbeaten on 42, as they ended on 288 for 7.
Dominic Cork quickly wrapped up Northamptonshire's innings, as Lancashire dismissed the home side for 289, Cork ending with impressive figures of 4 for 27. Lancashire stuttered in reply, however, losing three wickets to Jason Brown. Brown and Monty Panesar bowled 68 of the 94 overs in Lancashire's innings, and it was Brown who dismissed Stuart Law, the only batsmen who could stay for any length of time at the crease. His 111 was his third hundred of the season. With just two wickets left, and trailing Northants by nine runs, bad light called an end to proceedings.
Only 51 overs were possible at Worcester with Worcestershire struggling on 177 for 4 against Leicestershire. It was an encouraging start for the home side whose openers, Chris Gayle and Stephen Moore, put on 75 for the first wicket. Gayle's typically aggressive half-century, at nearly a run a ball, was ended on 51 when he was caught behind off David Masters. But Ben Smith and Graeme Hick soon followed, and as rain forced the players off, the home side were still 228 runs behind with six wickets in hand.
