|Royal London One-Day Cup, The Kia Oval|
|Surrey 265-8 (50 overs): Ansari 66 not out, T Curran 44; Carver 2-40|
|Yorkshire 259-7 (50 overs): Ballance 77, Maxwell 55; Ansari 3-58|
|Surrey won by six runs|
Gary Ballance's second consecutive fifty for Yorkshire in the One-Day Cup was in vain as his side suffered a six-run defeat by Surrey at The Oval.
Ballance, dropped by England for this week's third Ashes Test at Edgbaston, hit 77 but fell late on as Yorkshire, chasing 266, finished on 259-7.
Glenn Maxwell also struck 55, but Zafar Ansari's three wickets, including that of Ballance, proved crucial.
Earlier, Ansari hit 66 not out and Tom Curran smashed 44 in Surrey's 265-8.
Ballance, who made 69 against Derbyshire two days earlier, looked to be guiding Yorkshire to another victory as he helped reduce the target to 22 from 15 balls.
However, once he was caught by Ben Foakes off spinner Ansari, the rest of the lower order were unable to get the Surrey bowlers away.
Surrey all-rounder Zafar Ansari told BBC London 94.9:
"They were favourites for most of their innings but we stuck in there and we just managed to take enough wickets at the right times to keep them in trouble and keep us in the game.
"We bowled probably better than they did at the death and that was the difference."
Yorkshire batsman Gary Ballance:
"It was a bit disappointing. We were set up nicely and gave ourselves a good chance but we didn't finish it off.
"It was a used pitch so there was a bit there for the slower bowlers and you had to work hard for your runs. We would have liked to restrict them to 20 or 30 less and it would have been the perfect chase.
