Head Coach Robert Croft believes disappointing mistakes were punished by a strong Warwickshire outfit at Edgbaston.
England international Ian Bell produced two centuries in two innings for the hosts and Croft hopes his Glamorgan side can use the defeat as a learning experience.
"Guys with about 160 Test matches in their locker got a lot of their runs. Our guys have had hours to watch how the best go about their job and I'd be pretty disappointed if they haven't picked up any tips along the way.
“Fair play to Ian Bell, he put on an exhibition of batting both in first and second innings and that’s part of the learning for our young side. We competed for most of the game, we made some good moves in it and we made some disappointing mistakes.
“To give five wickets for 29 to their leg-spinner [Josh Poysden] in the first innings was particularly disappointing, then after a good fight-back in the first two sessions on day three, we lost our last five wickets for 51. If you eradicate those two mistakes then hopefully we have got another 80-100 runs on the board which puts us in a far better position for the final day.
“We had a patchy performance on the final day, there were periods of control but sometimes you try to force things a bit too much and it comes undone, but nice for Andrew Salter to get career-best figures and a spirited performance from David Lloyd.”
