Yorkshire sealed promotion back to Division One of the County Championship after dominating day three against Northamptonshire.
Promotion rivals Middlesex were bowled out for 271 by Sussex, which left Yorkshire needing 350 in their first innings to secure second place in the table.
Adam Lyth (147) and James Wharton (162 not out) hit centuries as Yorkshire got the three batting bonus points they required and reached the close on 371-2.
Yorkshire were relegated to Division Two by one point in 2022, and then docked 48 points last season for their handling of the Azeem Rafiq racism scandal.
