Wellington: Mathew Sinclair, who made a double century on his Test debut for New Zealand, has announced his retirement from all forms of cricket at age 37.
Australian-born Sinclair, who played 33 Tests and 54 one-day internationals, made 214 on Test debut against the West Indies in 1999; then the second-highest total by a debut batsman.
Though he made 204 against Pakistan the following season and was a prolific scorer in first class cricket - with more than 13,000 runs - Sinclair struggled to command a regular place in New Zealand's team.
He was dropped from the New Zealand contract list in 2007, though he was recalled for one Test against Australia in 2010.
