Ian Thomas scored his first one-day half-century as Glamorgan beat Derbyshire by six wickets in their NUL clash at Cardiff.

The 22-year-old left-hander, deputising for the injured Jimmy Maher, shared in an opening stand of 91 in only 14 overs with Keith Newell in their pursuit of 200 to win.

Thomas' 50 came up in just 40 balls, with a six and eight fours.

Newell also went to a half-century as Glamorgan passed 100 in the 17th over and reached the winning post with 26 balls to spare.

Glamorgan were indebted to a quick start, especially as they lost wickets at regular intervals on the way to victory.

But a responsible 40* from Maynard guided Glamorgan to their fifth division two victory of the season to keep them in touch with the promotion race.

Half-centuries from Steve Stubbings and Matthew Dowman were the mainstays of the Derbyshire innings after stand-in skipper Michael Di Venuto, deputising for Dominic Cork and the injured Tim Munton, won the toss.

Derbyshire suffered a setback when Rob Bailey was dismissed to the fourth ball of the innings from Andrew Davies, but despite also losing Di Venuto, Derbyshire were indebted to Stubbings and Dowman, who contributed 109 in 24 overs.

The spin of Croft and Cosker slowed Derbyshire's progress, with Cosker taking three wickets, two in one over including a very sharp caught and bowled. Darren Thomas got into the action by dismissing Nathan Dumelow and Paul Aldred with consecutive balls as the Derbyshire innings rather tailed off with only 54 runs coming from the final 15 overs.
