Hampshire County Cricket Club [SEP] Origin of club
Hampshire County Cricket Club was founded on 12 August 1863 and played its first first-class match against Sussex at the Antelope Ground, Southampton on 7 and 8 July 1864. Sussex won by 10 wickets with James Lillywhite claiming ten wickets in the match for 80 runs, including his 100th career wicket. Hampshire was recognised as a first-class team from 1864 to 1885. In 1886, Hampshire lost its status after years of difficult circumstances and poor results. The team did play against Surrey and Sussex in 1886 but the matches were considered minor standard. Hampshire recovered first-class status from the beginning of the 1895 County Championship season when the team was invited to join the now official County Championship.
