Glamorgan captain Mark Wallace was disappointed with the poor start that led to their nine-wicket County Championship loss against Surrey.
Surrey bowled Glamorgan out for 232 in their first innings in Colwyn Bay, then posted a mammoth 589-8 declared.
Glamorgan responded with 398 in their second innings, but that left the visitors needing just 41 runs for victory late on day four.
"We let ourselves down with the bat in the first innings," Wallace said.
"We were probably 100 runs below par and that's what ended up costing us.
"In the last part of the game we did show a lot of fight and we played very well in the second innings.
"We're very disappointed to lose a game on what was a pretty placid surface, but we'll have to move on.
"We're a far better side than we've shown in this game against a good Surrey side over the four days and it went down to the last session."
Despite the defeat to Surrey and their previous 249-run loss to Worcestershire, Glamorgan are fourth in Division Two and can make up ground when they go to second-from-bottom Derbyshire on for a game that starts on Sunday, 20 July.
Before that the Welsh county have three T20 Blast games to play, away to Surrey on Friday and Sussex on 15th July, before hosting Essex at the Swalec Stadium on the 18th.
Glamorgan are also fourth in the South Group and could make real strides up the table by beating Essex and Surrey, who are both ahead of them.
