Dean Cosker admitted that finishing with figures of 4/25 against Surrey, but ending up on the losing side was a bitter pill to swallow, after Glamorgan fell 19 runs short of Surrey's total of 147/8 off their 20 overs on Friday night.
Cosker had led a bowling revival to restrict Surrey to a score that seemed within Glamorgan's reach, especially considering the pace at which Jason Roy was scoring early in the piece, blasting 61 off 47 balls.
Cosker and fellow slow bowlers Colin Ingram (2/20) and Andrew Salter (1/23) spun the game back the hosts' way in front of a boisterous SSE SWALEC crowd, but it was not enough as Azhar Mahmood's spell of 4-1-14-3 thwarted the home reply.
The 37-year-old veteran spinner also refused to blame a pitch that appeared difficult for batting, citing Glamorgan's inability to convert a winning position into points.
Cosker said: It's a little bit bittersweet for myself, I thought the wicket was in our favour and we thought that 140 was chase-able.
We've used the pitch quite a few times now but you can't blame the surface, somebody has got to put their hand up and try to perform for the next game. I would have liked to come away with a win [after taking 4/25].
Glamorgan's next game is away at in-form Somerset on Sunday afternoon and Cosker is keen for them to bounce back with a vital victory at Taunton.
He added: It's a big game for us. They're all must win games right now, we've got a bit of a rivalry with Somerset and we'll have a bit of banter with the Somerset lads.
Glamorgan's subsequent three games are all on the road, with the next home game in the NatWest T20 Blast on July 24th when Gloucestershire visit The SSE SWALEC.
