Pietersen and Hussey lead the overseas charge

Frizzell County Championship Division One

Warwickshire v Nottinghamshire at Edgbaston
Scorecard
Kevin Pietersen's second century of the summer put Nottinghamshire in a strong position at Edgbaston, as they closed on 389 for 3 after dismissing Warwickshire for their overnight score of 351. Pietersen smacked an unbeaten 140 off 178 balls to build on a second-wicket stand of 146 between Guy Welton (99) and Usman Afzaal (72), and added 146 in 33 overs in an unbroken fourth-wicket partnership with Chris Cairns (52*). Pietersen was at his best, hitting 90 in boundaries, including a towering six over the pavilion off Mark Wagh. Little went right for Warwickshire. Melvyn Betts suffered a groin strain in his third over and limped off shortly after lunch, and Waqar Younis (0 for 59) and Collins Obuya (0 for 40) both looked uninspired.

Kent v Sussex at Tunbridge Wells
Scorecard
Sussex took their overnight score to 311 at the Nevil Ground. A rapid 43 from Mushtaq Ahmed at No. 10 was the highlight of a consistent batting performance, while Robin Martin-Jenkins contributed a composed 67. Paul Hutchison scored 18 and bowled five overs before James Kirtley completed the long trek from Chester-le-Street to Canterbury and took his place in the side after being left out again by England. And it was Kirtley who took two wickets to reduce Kent to 90 for 3, before Andrew Symonds (54) and Matthew Walker (30) appeared to have stopped the rot with a fourth-wicket stand of 90. But Mushtaq grabbed both their wickets in the dying overs to leave Sussex on 188 for 5.

Lancashire v Leicestershire at Liverpool
Scorecard
Andrew Flintoff's good form with the bat continued as he cracked an unbeaten 71 to help Lancashire to 503 for 6, their highest total at the Aigburth ground. Flintoff, playing as a specialist batsman because of a trapped nerve in his shoulder, took his first-class average for the season to over 100 in his 55-ball onslaught. Mark Chilton (108) completed his hundred in the morning, and then Carl Hooper (74) and Stuart Law (82) put on 123 in 26 overs as Leicestershire wilted. Flintoff was back in the spotlight when Leicestershire batted, catching the debutant John Maunders (16) off Sajid Mahmood, and then Hooper took a superb low slip catch to account for Virender Sehwag (30). Leicestershire closed on 117 for 4, still 386 in arrears.

Middlesex v Essex at Lord's
Scorecard
Middlesex continued their fightback from 23 for 3 yesterday, and were finally all out for 363 at tea, before reducing Essex to 95 for 8, still 119 short of the follow on, by the close. Ben Hutton made 107, with 15 fours, and shared a stand of 103 with Abdul Razzaq (54). Paul Weekes (51*) organised the tail, and added 42 for the ninth wicket with Simon Cook (20) and 39 for the last with Chad Keegan (21). Jon Dakin finished with 5 for 86. But four catches from the wicketkeeper David Nash, and 3 for 7 in seven overs (including six successive maidens) from Simon Cook left Essex in tatters. The key wicket was that of Will Jefferson, brilliantly caught by a diving Nash for 22.

Frizzell County Championship Division Two

Glamorgan v Derbyshire at Swansea
Scorecard
Play got under way a day late at St Helen's, and Glamorgan made up for lost time by scoring 395, largely thanks to their acting captain, Robert Croft (84), and Dean Cosker who put on 81 for the last wicket. Tom Lungley was the chief destroyer for Derbyshire with 4 for 101 as Glamorgan slipped to 216 for 5, but Croft shepherded the tail sensibly to almost double their score. Derbyshire survived the last four overs of the day unscathed.

Gloucestershire v Northamptonshire at Gloucester
Scorecard
Gloucestershire's bowlers must have nightmares about bowling to Michael Hussey, the Northants opener and captain from Australia. Last year in the corresponding fixture (at Bristol) he romped to 310 not out. This time he made do with just 264 - with 35 fours and two sixes - before Jon Lewis had him caught. Hussey put on 260 for the sixth wicket with Gerard Brophy, who had reached 152*, his highest score for Northants, when Hussey declared shortly before tea at a towering 622 for 8. Gloucestershire's reply started well as they reached 96 for 0, but Carl Greenidge struck twice in three balls and then in the next over Andre Nel twice in two as four wickets fell for no runs. By the close Gloucestershire were 109 for 4, 364 runs short of avoiding the follow-on.

Hampshire v Durham at Southampton
Scorecard
An eighth-wicket partnership of 123 between Dimitri Mascarenhas, who spanked 14 fours in his 92, and Shaun Udal (60*) converted a handy Hampshire total into a huge one at the Rose Bowl. They were all out shortly before tea for 456. Earlier Simon Katich took his overnight score to 135, and Nic Pothas made 79: Danny Law and Nicky Phillips finished with four wickets apiece. Durham's reply stalled when they lost two wickets in successive overs at the end of the day, but debutant James Lowe, only playing because of a long list of Durham injuries, was still there on 41 as they closed on 107 for 2.

Somerset v Worcestershire at Bath
Scorecard
A fine allround performance from Andrew Hall put Worcestershire into a commanding position against Somerset at the Recreation Ground. First Hall cracked six sixes and 11 fours in his 104 as Worcestershire amassed 538, and then took 2 for 27 as Somerset were skittled out for 238, and made to follow on 300 runs adrift. On a good pitch, Jamie Cox's 37 was the top score in Somerset's innings as they lost their last eight wickets for 123, and it would have been far worse but for a belligerent 35 not out from a limping Nixon McLean at the end. Somerset reached 19 for 0 second time around.

University Match

Bradford/Leeds UCCE v Yorkshire at Bradford
Scorecard
Ismail Dawood, the Bradford/Leeds captain, hit 125 out of 241 in reply to Yorkshire's big first-innings total of 409 for 3 at Bradford. Dawood, who hit 16 fours and a six, didn't get much support - the next-highest score was Mark Bagley's 26. Yorkshire didn't enforce the follow-on, cruising to 140 for 2 from 26 overs in the final session.
