Jacques Rudolph flogged an imperious 191 from 267 balls - his second score in the 190s this season alone - as Yorkshire piled on the runs after winning an important toss against Somerset at Taunton. Rudolph, who made 198 against Worcestershire in April, cracked 29 fours before being bowled by David Stiff midway through the afternoon session, and such was his dominance that none of his team-mates got a look-in. The next highest score in the innings was Anthony McGrath's 40, although he endured a nasty moment when he was struck flush in the visor by an Alfonso Thomas bouncer. Thomas, with 3 for 50, was the pick of the attack, as Yorkshire closed on 375 for 7.

Jim Allenby was run-out four runs short of a deserved hundred, and James Taylor cracked an unbeaten 86, as Leicestershire dominated the first day against Derbyshire at Derby. The visitors were reduced to 25 for 2 as Graham Wagg and Ian Hunter each struck early blows. Boeta Dippenaar (38) and HD Ackerman (49) put on a stabilising 90 for the third wicket before Hunter removed the pair in quick succession. But Leicestershire's middle-order held firm, with Allenby and Taylor notching a fifth-wicket stand of 177 - Allenby the quicker of the two, cracking 11 fours in his 133-ball 96. Though he fell towards the end of the day, Leicestershire went to stumps content on 341 for 5 with Taylor 14 short of a hundred.
Owais Shah, the forgotten man of England's middle-order, fired a timely reminder of his abilities with a superb 159 from 252 balls, to single-handedly keep Middlesex in a position of strength against their London rivals, Surrey, at Lord's. Though he fell shortly before the close to give Andre Nel a richly deserved second wicket in 21 overs of sweaty toil, Shah's innings ensured Middlesex reached the close well place on 269 for 5, a position that might have been even more promising but for the dismissal of the nightwatchman, Steven Finn, to the last ball of the day. Shah aside, none of Middlesex's batsmen was really able to make hay while the sun shone. Billy Godleman was run out for 48 from 200 balls, having been very much Shah's junior partner in a second-wicket stand of 157.
Vikram Banerjee claimed 3 for 58 with his left-arm spin as Gloucestershire restricted Kent to 231 at Beckenham before shipping two wickets of their own in the 19 overs remaining before the close. In a cagey day's cricket, no one batsman was able to take command, with Martin van Jaarsveld's 53 from 81 balls the best on show. Kent won the toss and chose to bat, but from a comfortable 75 for 1 they began to ship wickets as Gloucestershire's bowlers shared the spoils. Steve Kirby extracted the key pair of Geraint Jones (46) and van Jaarsveld, while James Franklin added Darren Stevens to his earlier dismissal of Sam Northeast. In reply, Gloucestershire closed on 69 for 2, with Kadeer Ali and Alex Gidman both 18 not out.
