Wins for Warks and Middlesex
Middlesex, Nottinghamshire, Warwickshire and Gloucestershire all secured victories in Sunday's LV= County Championship action.
Middlesex claimed Surrey's last five wickets for 36 to secure a thrilling three-run win in the London derby at Lord's.
Resuming on 95 for five and needing a further 41 for their first victory at the home of cricket since 1997, Surrey were unable to cope with the seam movement generated by Middlesex's Tim Murtagh, Gareth Berg and Toby Roland-Jones and allowed the hosts to pick up the five wickets they needed inside an hour.
Murtagh finished with four for 43 and Roland-Jones four for 25, including the pivotal wicket of Rory Hamilton-Brown for 63 as Surrey were skittled out for 137.
Nottinghamshire were held up by some defiant tail-end batting by Durham before clinching their second win from two games by 114 runs.
Needing to take one wicket on the final day at the Emirates Durham ICG, with the hosts resuming on 203 for nine, number 11 batsman Mitch Claydon proceeded to his maiden half-century to keep Durham's slim hopes of victory alive.
But Claydon eventually succumbed on 55, caught at long-on by Luke Fletcher off Samit Patel, to leave Durham all out for 253 with Graham Onions unbeaten on 28 in a last-wicket stand of 73.
Warwickshire survived a major scare before launching their campaign with a two-wicket win against Somerset at Edgbaston.
Chasing a target of 259, last year's runners-up seemed to be cruising home until Peter Trego turned the game upside down with four wickets in 23 deliveries.
Warwickshire nosedived from 190 for three to 207 for eight in half a dozen overs, but Jeetan Patel stoked up a spectacular counter attack in scoring 43 of the 55 runs added with skipper Jim Troughton to steer the home side to victory.
In Division Two, Will Gidman and Ian Saxelby bowled Gloucestershire to a tense 33-run victory over Hampshire at the Ageas Bowl.
Hampshire were set 290 to win, but were bowled out for 256 with only a handful of overs remaining.
Gidman took four for 66, while Saxelby did the early damage in a three-wicket burst at the top of the Hampshire order.
Gloucestershire were earlier bowled out for 179 in their second innings, with Ian Cockbain top-scoring on 47.
Hampshire's reply began dismally as they lost their first six wickets for 72, but
seventh-wicket pair Michael Bates and Chris Wood fashioned a stand of 118 to give the hosts a fighting chance.
However, Bates was eventually bowled by Gidman for 87, allowing Gloucestershire's bowlers to gain the upper hand.
