|Surrey 157-6 (20 overs) beat Sussex 147-7 (20 overs) by 10 runs|
England Twenty20 bowler Jade Dernbach held his nerve to inspire Surrey to a 10-run victory over Sussex at Hove.
Michael Yardy (44), Scott Styris (35) and Rory Hamilton-Brown (34) put the hosts in a strong position on 137-5.
But Dernbach (3-15) conceded only four runs from the final over as Sussex, who needed 11 to win, fell short on 147-7.
Earlier, Jason Roy (42), Gary Wilson (31) and Azhar Mahmood's 23 from 13 balls helped Surrey to 157-6, while Dwayne Smith took 2-11.
Despite slipping to 81-4 in reply, Sussex looked in control, especially when Styris smashed three sixes in a 24-ball innings.
But his dismissal with 14 balls remaining began the home's side demise, and brilliant bowling from Dernbach and Mahmood, who conceded three runs from the penultimate over, ensured Surrey made amends for Wednesday's defeat by Hampshire.
