Roy's efforts dampened by rain
Jason Roy scored his third one-day century for Surrey but it all counted for nothing when rain arrived during the interval to wash out their Yorkshire Bank 40 Group B game with Durham Dynamos at a wind-swept Kia Oval.
The 22-year-old right-hander scored 117 from 111 balls, the lion’s share of Surrey’s modest total of 216 all out, as Durham pegged back the hosts' breezy start through Chris Rushworth, with 4-44, and two apiece for Ben Stokes and Paul Collingwood.
But his innings, and indeed the match, was subsequently overshadowed by an injury to Durham and England one-day international all-rounder Stokes and then the persistent rain.
Stokes, back-peddling at long-off, took a superb overhead catch to account for Roy but landed heavily on the outfield and lay prone for the next five minutes receiving treatment.
Complaining of pain in his lower back, Stokes was transferred to a stretcher and subsequently taken to hospital by ambulance for scans.
Earlier in the evening, having lost the toss, Surrey looked set for a storming start, despite strong winds sweeping the ground and the continual threat of rain.
In-form Steven Davies, fresh from a century earlier in the week against Hampshire, clattered a boundary off the fifth ball of the match, then pulled a short one from Mark Wood into the seats for a six.
The left-hander's cameo ended on 16 when, in looking to turn a Rushworth delivery to leg, he found a leading edge to be caught low down at mid-off.
Roy teamed up with Vikram Solanki to add 44 for the second wicket before the former Worcestershire batsman, in looking to run one down to third man, edged one from Stokes through to the tumbling Phil Mustard.
Though his timing was never at its best, Roy battled through to a run-a-ball half-century as he and Zander de Bruyn posted a further 75 inside 15 overs until the introduction of wily swing bowler Collingwood knocked the stuffing out of the Surrey middle order.
The former England stalwart snared de Bruyn leg before then, three balls later, sent Gary Wilson packing in identical fashion for a third-ball duck.
Collingwood was again in action when Zafar Ansari pushed toward backward point and set off for a single, only to be run out by Rushworth's throw when Roy refused to run.
In only his third List A game, Tom Jewell whipped across the line of a straight one from Rushworth to go lbw leaving Roy to scramble a single with his sixth partner of the innings to reach his 101-ball ton with 11 fours.
Surrey's acting skipper Gareth Batty departed to the next delivery after Stokes rearranged his stumps then, with 200 on the board, Roy's 142-minute stay was ended by Stokes' acrobatic, but ultimately painful catch in the deep.
Jade Dernbach and Gary Keedy failed to trouble the scorers yet, with Durham in the ascendancy, the rain arrived to bring an early halt to proceedings.
Durham later issued a statement via their Twitter account, which suggested Stokes' injury was not serious.
It read: "Ben hurt his back taking a very good catch. He experienced acute sharp pain in hitting the ground.
"He was removed from play on a spinal board as a precaution and has gone to hospital for further examination.
"He was moving his legs and had no neurological symptoms. Hopefully he has just jarred it."
