Clough joined Nottinghamshire from Yorkshire on a summer contract for the 2000 season. Producing some excellent all-round cricket for the Second Eleven – batting average of 26.66, bowling of 19.05 – he enabled the side to finish 4th in the Championship table.
The following season Notts Seconds rose to third place and Clough remained the principal all-rounder. At the same time he appeared in four Notts first-class matches and no less than 20 limited overs games. The future seemed most promising, but though he played another seven years at Trent Bridge, his first-class career was virtually over!
He would be chosen for only seven more first-class matches over those summers. On the other hand he was an almost permanent fixture in the One Day squad. His agility in the field and ability to bowl tidy spells made him an ideal component of the team in limited-overs cricket; Clough played in 135 One Dayers for Notts, taking 117 wickets and hitting 910 runs. He retired, in part due to injury, in 2008 and became a teacher.
