Jason Clark was born on March 26th, 1969 in London, England. He made his TV debut in 2004 and is nicknamed 'Cockney Jock'. He has qualified for the two World Championships. In 2005 he reached the second round before being defeated by Chris Mason.

The following year he again got past the first round but was beaten by eventual runner up Peter Manley. He also played in the 2006 UK Open but was eliminated in the 2nd round. Clark is one of the promising players on the fringe of things but could make an impact in upcoming years.
