Sooryavanshi achieved the milestone in Bihar's SMAT opener against Saurashtra.
Sooryavanshi eclipsed the record held by Croatia's Zach Vukusic, who captained his national side against Cyprus at 17 years and 311 days in August 2025.
After winning the toss and electing to bat first against Jaydev Unadkat's Saurashtra, Sooryavanshi opened the batting and scored 18 runs off 12 balls with 2 fours and 1 six before being dismissed by Chetan Sakariya.
Earlier this month, the Bihar Cricket Association appointed Sooryavanshi as skipper for the opening two fixtures of the tournament, with Suraj Kashyap serving as vice-captain.
Following Bihar's second match against Railways on November 16, Sooryavanshi is scheduled to join the India A squad in Doha for the ACC Men’s Asia Cup Rising Stars tournament.
This captaincy debut caps off a landmark 2026 season for the wonder kid. Earlier this year, he won both the MVP and the Orange Cap while playing in the IPL the Rajasthan Royals, scoring 776 runs at a strike rate of 237.30.
Sooryavanshi made his senior T20I debut for India on the tour of England in July and also served as vice-captain for East Zone during their title-winning 2026–27 Duleep Trophy campaign.
