Surrey's first LV= County Championship match since their relegation to Division Two last season ended in defeat by 10 wickets after they suffered a dramatic collapse on the final day against Glamorgan at The Oval.
The hosts, 50 for two overnight in their second innings and with a lead of 121 runs, slumped to 81 all out before lunch, Graham Wagg ripping through them with four for 10 to finish with career-best figures of six for 29.
Michael Hogan took the other four wickets for 31 and Glamorgan were left needing 153 runs to win, which they secured without loss as openers Gareth Rees and Will Bragg claimed a half-century apiece.
Australian Steve Magoffin blew away Middlesex's lower order to ease Sussex to victory by an innings and 127 runs at Hove in Division One .
Beginning the final day on 57 for one the visitors, who were skittled for 105 in their first innings, would have hoped to have made their opponents at least work for their win.
However, they crashed to a miserable defeat after failing to even reach the sanctuary of the lunch interval as they lost all nine remaining wickets in the morning session to be bowled out for 154.
Elsewhere in Division One, Nottinghamshire claimed a 45-run win over Lancashire at Trent Bridge.
Lancashire made 303 in their second innings with Ashwell Prince weighing in with 100 from 181 balls before he was the last man out, bowled by Harry Gurney (four for 81), but the visitors were always struggling after losing opener Luis Reece for six with wickets falling at regular intervals.
Worcestershire captain Daryl Mitchell lit up the final day of the clash against Hampshire with a superb century before the teams settled for an expected draw at the Ageas Bowl.
Mitchell notched the first ton of the new Division Two season as he scored a magnificent 172 not out at the top of the order, helping his side pick up four batting bonus points before declaring on 350 for seven.
That gave the visitors a first-innings lead of 87 over Hampshire, but with less than a session to go in a match badly hit by the weather, a draw was always the most likely outcome.
