A busy September month, including eight matches, did not yield a single victory. After the Leicestershire loss, they drew with Worcestershire, before the team lost two National League games to Durham and Derbyshire. On 19 September Yorkshire secured promotion, drawing with Derbyshire and taking full bonus points to go an unassailable 22.5 points ahead of Essex. In the National League, however, they reinforced their place as the worst of the 18 counties (Scotland excluded) with a loss to Warwickshire, before losing to Northamptonshire and Sussex Sharks in the Championship and League respectively.
