GLAMORGAN coach Toby Radford rated his team's seven-wicket victory against Surrey as the best of his spell at the club.
A clinical performance by the visitors in Guildford wrapped up a third successive LV=County Championship win of the season with 29 overs to spare.
Third-placed Glamorgan have now closed the gap on Surrey to only 12 points and also have a game in hand.
They are still 60 points behind Lancashire, who are top of Division Two with six wins and 167 points from their nine matches so far.
The win represented a remarkable recovery for the visitors, who had collapsed to 106 for 6 in reply to Surrey's first innings total of 406.
Graham Wagg and Mark Wallace initiated the recovery on day two with a 152-run partnership for the seventh wicket before Wagg raced to his double century the following morning.
Surrey then collapsed in their second innings against Michael Hogan's hostile bowling, losing their last five wickets for four runs in five overs. That set the scene for a calm run chase with Will Bragg top-scoring with 83.
"That is the best win since I have been involved with the club," said Radford, who took over the reins last year.
"When you look back when Surrey were 208 for 0 in their first innings and we were 106 for 6, it just shows the competitive spirit within the side.
"It was a terrific effort from Graham Wagg and Mark Wallace and also Michael Hogan, who bowled as well as he's done all season."
Surrey resumed on 276 for 8 but after five balls their innings was over. Wagg removed Vikram Solanki's middle stump with his fourth ball and then bowled Stuart Meaker.
Glamorgan's target was 247 in 93 overs and they were given a solid start by Jacques Rudolph and Bragg – the left-handed combination putting on 77 before the South African drove Gareth Batty to mid on.
Bragg was then joined by Ben Wright, playing in only his second championship game of the season, and neither appeared in any trouble against a Surrey attack who were without Chris Tremlett for all but five overs because of a hamstring injury.
Earlier Rudolph had struck Zafar Ansari for three successive fours in his first over and neither Ansari nor Batty, the two spinners, achieved any turn from the dry pitch.
Bragg was the first to reach his fifty from 111 balls with six fours and Wright reached his landmark from 12 balls fewer and seven boundaries.
The second wicket pair had put on 128 in 38 overs before Wright set off for a risky single was rightly sent back by his partner but was comfortably run out at the bowler's end .
Colin Ingram made his intentions clear by hoisting Ansari on to the members' tent at long on but Bragg departed with seventeen needed when he nicked Meaker to the wicketkeeper.
But Glamorgan achieved their victory with a session to spare and it is the first time the Welsh county have recorded back-to-back away championship wins in Surrey.
