Durham lost a second eleven trophy match for the first time this season, as a Kieran Bull-inspired Glamorgan cruised to a 112 run victory at Middlesbrough.
Off-spinner Bull (5-36) dismissed a number of key batsmen as Durham slumped from 88-1 to 169 all out in the space of 20 overs.
Despite this defeat Alastair Maiden's side remain third in the north division table, just a point behind Glamorgan, who have now moved into top spot.
With captain Calum MacLeod away on international duty, stand-in skipper Usman Arshad won the toss and elected to field first.
Boasting a strong line-up that included Michael Richardson and Keaton Jennings, Durham would have been confident of restricting the visitors to a modest total. However, all but one of the Glamorgan batsmen reached double figures as the Welsh county compiled 281-9 in their 50 overs.
17 year-old Aneurin Donald hit six boundaries in a brisk innings of 53 from 51 balls, whilst Gary Knight (46) and Gareth Rees (43) made useful contributions.
Jennings (2-44) bowled 10 tidy overs, whilst there were two wickets apiece for Arshad (2-79) and Max Morley (2-36).
In reply, the hosts made a promising start as they reached 88-1 inside 16 overs. The in-form Graham Clark and first team regular Richardson were at the crease and the run chase looked to be fairly straightforward.
But then Richardson, who has scored over 600 first class runs this season, was trapped lbw and suddenly Durham started to collapse.
Bull accounted for Clark (46), and although Stuart Poynter (38) offered some resistance, the young Glamorgan bowler wrapped up the innings to finish with five wickets as Durham stuttered to 169 all out.
The two sides meet again in a three-day championship match at Middlesbrough CC starting on Tuesday at 11am.
