Glamorgan suffered their third defeat of the Vitality Blast campaign as Middlesex won by eight wickets thanks to a flying start in the Powerplay and some tight bowling by their international stars.
The Welsh county struggled to build momentum, and skipper Colin Ingram admitted after the game that the side haven't been performing near their potential.
"We haven't taken good options upfront and we've lost early wickets," said Ingram. "We haven't got those partnerships so there's a lot to work on, but the guys are hungry and working hard."
"After three losses and another not-good batting display, we might have to look at a few changes, there are guys in the wings who are hungry to play,"
"If any team can do it (turn the campaign round), we know this is the team.
"Last year we had a similar slow start, it's an unfortunate position but I trust these guys, they're a group of characters who play hard."
