County Championship D1, Edgbaston, day three (close): Surrey 225 & 45-1; Warwickshire 338
A century by Nick Knight added to Surrey's relegation worries as they trailed Warwickshire by 68 runs at the end of day three at Edgbaston.
Knight notched 117- his second hundred in successive games - as his team posted a first innings total of 338.

But they lost Scott Newman, caught off Dougie Brown, when they batted again, reaching 45-1 at the close of play.
