A 214-run stand for the third wicket between centurions Anthony McGrath and Jacques Rudolph lifted Yorkshire to 359 for 5 on day one against Kent at Canterbury. Having added 97 with Adam Lyth (50) after the early loss of Andrew Gale, McGrath found a solid ally in Rudolph and the two clicked away at a good rate. McGrath's 144 from 226 balls was his first hundred of the Championship season, while Rudolph's unbeaten 121 was the fourth of season in which he has amassed 677 runs. Yasir Arafat took two wickets after McGrath fell with the score 341 for 3, but Rudolph and Matthew Hoggard held out until stumps.

Nic Pothas' hardworking 62 held Hampshire together against Lancashire at The Rose Bowl as the visitors shared the wickets around. Pothas, who came close to being run out by Lou Vincent before he had scored, battled hard against a strong attack after the top slipped to 85 for 4. Michael Carberry fell in the first over of the match, offering Glen Chapple a return catch, and Andrew Flintoff removed his former team-mate John Crawley with an edge to slip. Pothas took two sixes off Gary Keedy but finally fell having a wild slash at Chapple, sending an outside edge to Flintoff at second slip.

Rain limited the action to 33.5 oversat Bristol, but there was enough time in between the showers for the Gloucestershire bowlers to put Middlesex under pressure, the visitors struggling to 73 for 4. Jon Lewis accounted for the wickets of Billy Godleman (0) and Ed Joyce (13), while Steve Kirby had Dawid Malan smartly held by William Porterfield at second slip. In the 12th over Shah retired hurt with a knee problem, and though he was later to return, his stay was brief when he edged a short delivery to the wicketkeeper, Steve Snell. Eoin Morgan was on 23 before bad light curtailed a miserable first day for Middlesex.
