Surrey's first LV= County Championship match since their relegation to Division Two ended in defeat by 10 wickets after they suffered a dramatic collapse on the final day against Glamorgan at the Kia 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 4-10 in the session to finish with career-best figures of 6-29.
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.
Wagg took his first scalp of the day with the morning's opening deliver, which Zafar Ansari – so watchful in compiling a first-innings 74 - edged into captain and wicketkeeper Mark Wallace's gloves for a duck.
Hogan then bowled Dominic Sibley for 10 and ousted Gary Wilson for a duck via another Wallace catch, with Graeme Smith's Surrey still yet to add anything to their overnight tally.
They did boost their score by 11 to 61 before Wagg had Jason Roy caught at first slip by Jim Allenby and things somehow got even worse for the home side.
There was another wicket for Hogan as Tom Curran chopped onto his stumps and Steven Davies departed lbw to Wagg for 10, both dismissals coming with Surrey on 76.
After Wagg completed his six-for as Chris Tremlett went leg before, Hogan swiftly wrapped things up by bowling Tim Linley for another duck.
Back at the crease, Glamorgan - who had posted 209 first-time round in reply to 280 after winning the toss - got to 26 without alarm by lunch as they hunted down their victory target in a composed manner.
What a fantastic day. Boy's were brilliant. So, looking at results today if it rains for the rest of the summer we're Champs! ☔️☔️☔️☔️

And they soon reached it thereafter, ending up with 156 - Rees on 75 and Bragg 72 having struck 10 and seven fours respectively.
It was a state of affairs Glamorgan would have scarcely believed at the start of play, but captain Wallace’s 200th consecutive championship appearance truly proved one to remember.
