Glamorgan ended their Twenty20 Floodlit Cup campaign with a 24-run win over Sussex at Sophia Gardens, Cardiff.

After being put in, Mark Wallace and Richard Grant provided the mainstay of the Dragons innings, bringing up the 50 in only the fifth over.

But young Sussex spinner Tom Smith and Chris Nash put the brakes on as the Dragons finished on 146-8.

Despite some big hitting from Ollie Rayner in Sussex's reply, disciplined Glamorgan bowling saw off the visitors.
