One of the most exciting talents to emerge from the Indian domestic circuit, Sundar is a skilful left hand middle order batsman and off-spinning allrounder. He made his debut for India in the ODI series against Sri Lanka at Mohali in December 2017. Later in the month, he also made his T20I debut at Mumbai, becoming India's youngest ever T20I player. Four years later he made his Test debut in 2021 and was a part of the epic Brisbane Test victory in Australia. He has played for the Rising Pune Supergiants in 2017 and was a vital member in the Royal Challengers Bangalore setup in the following years. In the 2022 TATA IPL Auction he was bought for INR 8.75 crore by the Sunrisers Hyderabad.
