|Royal London One-Day Cup, Kia Oval|
|Surrey 328-7 (50 overs): Roy 99, Sangakkara 76, Burns 61|

|Surrey won by 36 runs|
Surrey reached the One-Day Cup quarter-finals with a 36-run victory over a spirited Worcestershire at The Oval.
England opener Jason Roy made 99, Kumar Sangakkara 76 and Rory Burns 61 in Surrey's 328-7 after they won the toss.
Half-centuries from skipper Daryl Mitchell (59), Tom Fell (63) and Joe Clarke (54) and a rapid 35 from Ross Whiteley gave the visitors hope.
But Whiteley's dismissal ended their chances as they were bowled out for 292 with 20 balls remaining.
Earlier, Roy looked set to reach his seventh one-day century after striking 11 fours, only to edge Joe Leach behind one short of three figures.
However, his second-wicket stand of 144 with Sri Lankan Sangakkara put Surrey on their way to the big total.
Some composed batting from Worcestershire's top order followed by Whiteley's explosive hitting, saw the target reduced to 72 from 46 balls.
But once Sangakkara caught Whiteley on the boundary off James Burke (3-51), the tail was left with too much to do.
Surrey top Group A with five wins from six games, while winless Worcestershire are bottom and all but eliminated.
