Former South Africa spinner Paul Harris will retire from cricket at the end of the 2012/13 season.

Having made his first class debut for Western Province during the 1998/99 season, the current Titans left-armer will call time on a 14-year career at first-class level.

Harris played 37 Tests for the Proteas and took 103 wickets and was part of the South African team that won series away in England and Australia in 2008.

"I will be retiring from cricket at the end of the 2012/13 season," he said. "I would like to thank the Titans franchise for all the opportunities that they have given me over the past 10 years. I have made many friends through cricket and I have had so many great experiences.

"I would like to thank all the people who have helped me over my career. A special mention must go to [Titans coach] Richard Pybus, who had the biggest coaching influence on my career. I am sure that I would not have played for South Africa if it had not been for him.

"I would also like to thank Ian Repton, the Nashua Titans physiotherapist; he really has gone above and beyond the call of duty to help me stay on the park over the last 10 years. A big thank you also goes to my agent and friend, Barney Girnun; he has been there from the start and has always supported me through thick and thin.

"Lastly, and most importantly, I would like to thank my wife, Marilet. The love and support that she has shown throughout my career has been unreal. It is not always easy being a cricketer's wife, and she has been a pillar of strength. I am now going to enjoy being a Titans and Proteas supporter."

Proteas Test captain Graeme Smith paid tribute to his former colleague via Twitter.

"It was a privilege to play with @paulharris12 played a big role in getting us to where we are today!all the best kook," he wrote.

"And I used to love it when @paulharris12 batted as a night watchmen, gutsy entertaining and full of bruises."
