|Friends Life t20, Richmond:|
|Glamorgan 104-6 (17.1 overs) beat Middlesex 102 (19.1 overs) by four wickets|
Mark Wallace hit an unbeaten 40 to ensure Glamorgan beat Middlesex by four wickets in the FL t20 and took advantage of their spinners' good work.
Only Chris Rogers (30) resisted as Dean Cosker (3-11) and Robert Croft (3-18) spun Middlesex out for 102 - their lowest Twenty20 score.
Ryan McLaren (3-7) gave Middlesex hope by reducing Glamorgan to 30-3 in reply.
But Wallace, backed by Alviro Petersen (39), steadied the ship before seeing his side home with 17 balls to spare.
Middlesex have now lost four of their five matches in the South Group and they had no answer to the flight and guile of Cosker and Croft on a slow turning pitch at Old Deer Park, Richmond.
Cosker took two wickets in three balls in his first over, seeing Rogers clip to mid-wicket before bowling Neil Dexter round his legs.
Croft conceded 10 runs in his first over but bowled Scott Newman, had John Simpson caught at mid-wicket and saw Jamie Dalrymple stumped before Cosker had Tom Smith caught at cover to leave Glamorgan in command.
Glamorgan lost Mark Cosgrove first ball and were in trouble when McLaren removed Jim Allenby and Ben Wright in successive balls, only for Wallace to provide the calm head to see them home.
BBC Wales' Edward Bevan:
"Glamorgan gained their second win in the competition thanks to their spinners and to two batsmen, Alviro Petersen and Mark Wallace.
"The margin of victory - four wickets - reflected how difficult it was to score on a sub-standard pitch.
"Middlesex were all out for 102 in 19.1 overs with Robert Croft taking 3-18 and Dean Cosker 3-11, Cosker the most economical figures from a Glamorgan bowler in the competition.
"Glamorgan then lost Mark Cosgrove to the first ball of their innings, but Petersen with 39 and Wallace 40 not out guided their side to victory with 17 balls to spare."
