Chad Keegan and Murali Kartik took three wickets apiece as Middlesex hustled Glamorgan to an 89-run defeat.

Asked to bat first at 1630 BST after a rain delay, the visitors made 183-5 in their 21 overs, Owais Shah and Ed Joyce both recording rapid half-centuries.

Glamorgan's chase soon looked unlikely as Chaminda Vaas trapped Richard Grant lbw first ball and Keegan took two wickets with consecutive balls.

Ryan Watkins resisted with 35 not out but the Dragons were all out for 94.
