Born in St. Athan, Wales, his father Sid was a six times Welsh champion. Mark won the 1976 British Boys Championship, and remains the youngest ever to do so at just 15 years old, in 1977 he was the BBC Wales Junior Sportsman of the Year and turned professional in 1981.
By 1986 he was well established on the European Tour, winning that year's Car Care Plan International and finishing 30th on the Order of Merit.
He broke his right ankle and left foot in a motorway crash that year, but recovered to record two top twenty Order of Merit finishes in 1987 (16th) and 1988 (18th).
Mark has enjoyed one of the longest careers in European Tour history with over 520 tournament appearances, which makes him the eighth most experienced player ever on The European Tour. With 4 victories - the Car Care Plan International, Dutch Open and Mauritius Open (2002 & 2003) as well as 15 representative appearances for Wales in the World Cup and Dunhill Cup competitions he brings with him a wealth of international golfing experience and knowledge.
Always recognised for a great short game, Mark was the No.1 putter on the European Tour two years in succession and still holds the record of just 19 putts in a round of tournament golf.
