Glamorgan\'s white-ball skipper Colin Ingram felt his side were just short of putting together a competitive score as Hampshire successfully chased a target of 228 in Swansea.
Ingram struck a half-century and Glamorgan looked comfortable while he was batting alongside Graham Wagg, but the hosts were restricted to 227 at St Helen's by Hampshire. The visitors lost six early wickets but dug in through Taylor 54* and Berg 52*, who saw them through to victory.
"It wasn't enough runs in my opinion," said Ingram.
"We made a few silly errors although the wicket was slow and we didn't adapt to it.
"It was disappointing, myself and Waggy got into a great partnership but if we could've batted another 10 or 12 overs together we might have put a good total on the board.
"It showed that if you stick in for long periods and get a good partnership somewhere then the game would start to flow. Two of their batters did towards the back end and really that was the game."
After posting a score of 227, Glamorgan took to the field and went to work on the visitors and at one point had Hampshire on 144/6.
"The guys showed the same attitude and fight in the field from the last game which was really encouraging. We seem to get a few wickets along the way and we probably just needed one or two more to really crack the game open.
"All credit to them, they played really well in their partnership and put us under a lot of pressure."
Despite a much-needed win against Sussex, Glamorgan have now lost six of their seven Royal London One-Day Cup matches. Ingram believes a lack of consistency has contributed to the team's fortunes.
"It's felt strange, there have been a couple of different things over the seven games. As a batting unit we haven't been as consistent as we have in the last couple of years and we haven't had big hundreds which has been frustrating for the team and myself personally."
A few injuries during the 50-over campaign have seen many of Glamorgan's Pathway players given an opportunity and Ingram is encouraged that there will be more to come from the Welsh county's younger crop of stars.
"We have a bunch of new faces and a lot of young guys who are still learning.
"I'm encouraging them all the time and they're showing good attitude. There have been some nice performances along the way but unfortunately as a group we haven't put enough together.
"I always like to take positives where I can and there's a lot left to play for in the season so hopefully we can kick on as a team."
