Roy made 99 off 95 balls while veteran Sangakkara reached 76 off 74 balls to help the home side rack up 328-7.

Elsewhere, Michael Klinger's fine season with Gloucestershire continued with a seventh century in a 72-run victory over Durham under the Duckworth-Lewis method at the County Ground.

The 35-year-old followed up his hundred in the previous game against Somerset by blasting an unbeaten 135 off 114 balls, with 12 fours and five sixes.

Kllinger helped the hosts post 289-7 either side of three rain breaks, which reduced the match to 41 overs per side.

The Australian battled with a hamstring problem which forced him to make his last 41 runs batting with Chris Dent as a runner.

And he was supported by Geraint Jones who made 54 and Benny Howell who struck 45 off 24 balls.

Scott Borthwick returned the best figures for a below-par Durham attack, claiming 3-26.

In reply, the visitors faced a target of 286 under Duckworth-Lewis but were bowled out for 214 in the final over.

John Hastings top scored with 46, while David Payne was the pick of the bowlers finishing with 5-40.

The result makes Gloucestershire favourites to reach the quarter-finals, having taken nine points from five Group A matches, while Durham face a battle to qualify on five points with two games left.

Derbyshire thrashed local rivals Leicestershire by six wickets in a one-sided game at Derby.

The Foxes were out for 156 in 41 overs with Alex Hughes claiming career best figures of 3-31 while Shiv Thakor took two for 28 against his former county.

And the Falcons reached their target with 19.1 overs to spare with Wes Durston following his century against Surrey on Sunday with 80 from 65 balls.

Tillakaratne Dilshan was dismissed in the first ball on his Derbyshire return but Thakor finished unbeaten on 27 to guide the hosts home.

The win sees the Falcons move into fourth place while winless Leicestershire remain eighth.
