The wicketkeeper-batsman first played for England at Under-14 level and continued to represent his country through the various age groups.
He played for the Under-19s several times in 1995 and 1996 and was also a member of the England A side, but never made the step up to full international level.
He has played some gutsy innings with the bat and formed some useful partnerships low down the order, although injury kept him out for much of the 2004 season and he was dropped in favour of Ben Scott for most of the 2005 campaign.
Although he played in all eight of Middlesex's Friends Provident Trophy games in 2007 and six championship matches, he lost out to Scott in every other game and had to ply his trade in the second team instead.
Nash was limited to three appearances, all in the championship, in 2008 but he managed 251 runs in six innings. This included a top score of 96 against Glamorgan.
He finally hung up his gloves at the end of the 2009 season.
