In the domestic game, Shaun played for Hampshire between 1988 and 2007.
Shaun was named Hampshire Cricket Society Player of the Year in 1993 and 2002.
Shaun played in ten One-day Internationals in 1994 and 1995, including the winter tour of Australia, but did not play for the Test team at that time. In September 2005, after an impressive season with Hampshire, he was recalled to the England squad for their tour of Pakistan. He made his Test debut in the first Test of that tour at the age of 36.
He retained his place on the Indian tour for later that winter, and returned to the side for the third and final Test in Mumbai. He was instrumental in England's victory, taking figures of 4 wickets for 14 runs in the second innings.
On 17 September 2007 he announced his decision to retire from cricket at the end of the 2007 season.
Middlesex lured him out of retirement to sign him on a 2 year contract. His first season was so successful that Middlesex made him captain of the county for the 2009 season.
Shaun was selected in the 30 man England squad for the ICC Cricket World Cup, to take place in the summer of 2009.
