Robin Singh was a wholehearted all-rounder, who moved to India from Trinidad, his birthplace at an early age. He made his first-class debut with Tamil Nadu, during the 1981-82 season. Apart from being able to both bat and bowl, he was a very good fielder and this meant he cemented his place in the side. The left-hander made his ODI debut on March 11, 1989, against West Indies at Port of Spain. However, he was dropped soon after and was recalled for national duty seven years later, for the Titan Cup in 1996.

By this time, Robin Singh was more a matured player and he didn't want to let his place go. He was a regular member of the side since then and scored his only ODI hundred, against Sri Lanka at Colombo in 1997. Singh loved to play against Sri Lanka and both his fifers, came against them. He batted in the middle-order was mostly in-charge of the death overs.

One of Singh's finest knocks for India came in the 3rd final of the Independence Cup against Pakistan in 1998. Chasing a massive 315, Singh was promoted up the order to No. 3 and he hit a positive 83-ball 82 and more importantly, was involved in crucial 179-run stand with Sourav Ganguly to help India cross the line.

Although Singh made his Test debut in the Only Test against Zimbabwe in 1998, he was never picked for Tests again as he was not considered a good material for the longest format. However, he continued to play the ODI format, until being dropped from the side in 2001. Three years later he quit all forms of cricket and became the coach of the Hong Kong national cricket team. He has also coached a few India 'A' sides and Deccan Chargers, in 2008, before signing up for the Mumbai Indians in 2010. Robin Singh also served as India's fielding coach from 2007 to 2009.
