Mark Wallace has announced his retirement from first-class cricket after an 18-year career with Glamorgan to join the Professional Cricketers' Association's team of personal development and welfare managers.

Wallace will still be involved with Glamorgan. His new role will involve helping his former team mates, as well as players at Gloucestershire and Somerset, to help improve their performance on the field through minimising potential distractions off it and also to assist them in preparing them for a life after cricket.

He takes over the role of his former Glamorgan colleague Ian Thomas who was recently appointed the PCA's Head of Development and Welfare.

"I've been extremely fortunate to have been able to represent Glamorgan for so long," said Wallace. "While I walk away with a heavy heart I'm delighted to be able to start the next chapter of my life with the PCA."

"I will be going back into Glamorgan in a different role and that will probably feel strange because nothing replaces playing. I've had my last day's training and now I'm an ex-cricketer, so it is an odd feeling. But I know the PCA very well. Being Chairman for four years has given me a real insight into the organisation and given me some real enthusiasm and drive to want to help players."

The most successful wicket-keeper batsman in Glamorgan's history, in 2011 Mark Wallace became the first gloveman for the Welsh county to amass over 1,000 first-class runs in a season.

Born in Abergavenny, Wallace made his Glamorgan debut in 1999 against Somerset at Taunton, and at 17 years and 287 days old he duly became the club's youngest wicketkeeper in a Championship match.
