Glamorgan fell to their first defeat in this year's Royal London Cup as Yorkshire Vikings secured a 23-run victory over the current 50-over champions.
Skipper Kiran Carlson rued the lack of partnerships in the Glamorgan innings with the Welsh county unable to build any momentum in their run chase on a tricky batting wicket.
"The pitch was a bit turgid and if you bowled in the right areas it was hard to get away. If we'd had more wickets in the hutch we could have gone harder earlier,” said Carlson.
"It was a bit of a strange game, they probably ended up getting about par but we lacked those partnerships in the middle. Every time we got one forming we lost a wicket.
"We didn't think the pitch would spin, but looking back another specialist spinner like Prem Sisodiya could have done a job for us. Hindsight is a great thing!"
Seamer Jamie McIlroy picked up an injury while running between the wickets and is likely to miss the next game, but will be replaced by an in-form James Harris.
"McIlroy's injury is gutting for us and for Jamie, hopefully it's not too serious, James Harris has bowled well for the seconds so he's the next one in if Mac is (out) injured," added Carlson.
