Singh was named as a stand-by player for the 2011 Champions Trophy in Ordos City, China, and was selected in the main squad following the dropping out of two players. However, he missed out as his passport was not ready at the time. Eventually, he made his debut in 2011, at the Champions Challenge I in South Africa. He was a part of the team that competed at the 2014 Commonwealth Games in Glasgow, finishing second, and a ninth-place finish at the 2014 World Cup. In the same year, he won the gold medal with the team at the Asian Games in Incheon.
