England hopeful Ollie Robinson took career-best second-innings figures of nine for 78 as Sussex beat Glamorgan by eight wickets in the LV= Insurance County Championship.
Billy Root was the only home batsman not to be dismissed by Robinson, who helped bowl the Welsh county out for 349 at Cardiff.
That left Sussex needing 154 for the win and they eased home following unbeaten half-centuries from Aaron Thomason and Tom Clark.
Simon Harmer took five for 57 as Essex completed a remarkable comeback to beat Durham by 44 runs at Chelmsford.
Defending County Championship and Bob Willis Trophy champions Essex had been bowled out for 96 in the first innings and gave up a 163-run deficit before turning the game on its head, racking up 330 the second time around and dismissing the visitors for 123.
Harmer claimed his 22nd five-wicket haul and sixth 10 wickets in a match since joining the county in 2017.
