The 18-year-old cricketer made his first class debut for Rajasthan in 2016-17. He played only one match and took two wickets in that match. Little did we know about him in 2017 until he was bought by Rising Pune Super Giants. Prior to that, he made his List A debut but took just one wicket in his first match. However, he improved and took eight wickets in six List A games. Playing for RPS, he bagged two wickets, that too of experienced players Hashim Amla and McCullum that caught people's attention.
The leg break spinner travelled with Indian U-19 team to England in August 2017. In England, he picked 10 wickets in just four One-Day matches with best bowling figures of 4/63. In spite of his good performance, he wasn't selected to be a part of the U-19 World Cup team.
This year, he played for Rajasthan in Syed Mushtaq Ali Trophy, the domestic T20 league and has shown potential at a young age. He impressed by taking six wickets in four games. The interesting fact is that in spite of having very less domestic experience, he was in demand during the IPL auction 2018. In auction, both Mumbai Indians and Rajasthan Royals showed their interest in buying the leggie spinner. It was Mumbai Indians team that won the bid and bought Rahul Chahar for a whopping 1.9 crore.
The young spinner would have tremendous opportunity to play alongside big names in this year's IPL. Even the guidance and support of the experienced Mumbai Indians players would help the youngster in growth further in his career. His inspiration is brother Deepak Chahar who is currently a part of Chennai Super Kings and played with him, for Rising Pune Supergiant in 2017 season.
