Hemp made his county debut in 1991 after impressive performances with the junior Glamorgan teams.
The left-handed batsman was selected for the England A tour to India and Bangladesh in 1994/5 following a prolific county season when he made 1,452 runs with his elegant strokeplay.
He left Glamorgan in 1997 to join Warwickshire but returned to the Welsh side in 2002, where he has since made considerable contributions, including a record second-wicket partnership of 252 with Matthew Maynard.
Hemp topped Glamorgan's home-grown batting averages in 2005, behind Sourav Ganguly and Matthew Elliott.
He was Glamorgan's highest run scorer for the season, with 1369 at an average of 44.
He made 171 not out against Kent at Canterbury, but Glamorgan still lost the match by an innings and 124 runs.
Hemp's battling batting throughout the year was, unfortunately, often a lone stand and he was unlucky to see Glamorgan suffer relegation to Division Two of the County Championship at the end of the season.
He was a solid performer during another difficult season for Glamorgan in 2006 and was rewarded with the county captaincy for the 2007 season.
In November 2006 Hemp made his international debut for Bermuda, the country of his birth, who are an ICC Associate side.
He recorded a career-best 247 not out for Bermuda in their four-day ICC Intercontinental Cup match against Holland in Pretoria.
In 2007 he played for his country in the World Cup, hitting 76 not out against India, in the West Indies before enjoying a consistent season for Glamorgan.
