A highly-regarded off-spinning all-rounder, there were high hopes for Hamilton-Brown long before he progressed through the Surrey ranks to captain England Under-19s.
He was a talented enough rugby player to represent Harlequins and England at youth level, but made his debut for Surrey against Bangladesh A in 2005.
Hamilton-Brown remained on the fringes of the first team, however, and asked to be released from his contract at the end of 2007, citing a lack of opportunities.
Although he became a key member of Sussex's one-day side, helping them win three trophies in two years, he played just six first-class games in that period.
Surrey - with former Sussex captain Chris Adams now installed as cricket manager - approached Sussex towards the end of 2009, and the county reluctantly released Hamilton-Brown from his contract a year early to allow him to return to the Brit Oval as captain on a three-year deal.
He helped orchestrate a winning culture at Surrey, leading them to LV= County Championship promotion and Clydesdale Bank 40 glory in 2011.
Hamilton-Brown was deeply affected by the death of close friend and Surrey team-mate Tom Maynard in June 2012 and was granted a period of compassionate leave during which he relinquished the captaincy. At the end of the season he decided to continue his career elsewhere and Surrey agreed to release him from his contract. He returned to Sussex on a three-year deal.
