Having restricted Worcestershire to a modest 175 and then having that target revised to 157 from 34 overs after rain intervened, Surrey were never in trouble and they reached 162 for 2 off just 24 overs.
Alistair Brown hit a trademark quickfire 55 off 39 balls, with the help of 10 boundaries, then Adam Hollioake made a spectacular contribution, smashing four sixes and three fours in an unbeaten 37-ball 47, with the winning runs coming courtesy of his fourth six.
Richard Illingworth gained some compensation when he claimed his 200th Sunday League wicket by having Brown caught in the deep by Vikram Solanki.
Kent, the Sunday League champions, slipped to an unexpected defeat by 22 runs to Gloucestershire. On a slow wicket at Moreton-in-Marsh they had felt comfortable as they restricted the home side to 165 for 7, but they did not recover from losing Matthew Fleming and Carl Hooper to Mike Smith in his second over.
Although Trevor Ward and Nigel Llong, who both scored 28, kept up the scoring rate, a run-out pushed them back into trouble. Martin McCague went without scoring, leaving Kent wanting 50 off the last eight overs. An expensive over by John Lewis brought them 15 runs, but then Smith and Courtney Walsh came back to take a wicket each as Kent were all out for 143.
Nottinghamshire's Chris Tolley's career-best figures of 5 for 16 meant Hampshire were beaten by 82 runs at Southampton. Tolley undermined the Hampshire batting with the home side losing their last seven wickets in six overs while adding 19 runs. From a prosperous 108 for 3 Hampshire fell away to 127 all out.
Tolley's achievement overshadowed another personal best from Hampshire's Kevan James who took 6 for 35. James, in a rich vein of form, was twice on a hat-trick.
An unbeaten century from Hugh Morris and an 87 from Matthew Maynard helped Glamorgan to a four-run victory over Essex at Chelmsford.
Durham slumped to another defeat by 60 runs at Derby. Their 10th Sunday defeat took their total of matches this season without beating a first- class county to 25.
