A left-arm quick, Arjun, had been picked in the Mumbai Under-19 one-day side for the JY Lele invitational tournament in September last year. He also bowled in the nets in the lead-up to the Lord's Test between England and South Africa in 2017, sending Jonny Bairstow off with an injury scare when he struck him on the toe with a yorker. Arjun also bowled in the India nets during the home series against New Zealand last year.
However, he did not find a place in the one-day squad that will play five games against Sri Lanka. The four-day squad will be captained by 18-year-old Delhi wicketkeeper-batsman Anuj Rawat, who had scored two half-centuries, including one on debut, in as many matches for Delhi during the 2017-18 Ranji Trophy.
"We are happy on Arjun being selected in Indian under-19 team. It is an important milestone in his cricketing life. Anjali and I will always support Arjun in his choices and pray for his success," Sachin told Mid-day.
The one-day squad will be led by 16-year-old Uttar Pradesh wicketkeeper-batsman Aryan Juyal, who had played two matches in the 50-over Vijay Hazare Trophy earlier this year and was part of the Under-19 World Cup winning team in January.
Seventeen-year old left-arm spinner from Gujarat Siddharth Desai was picked in both squads. He also made his first-class debut in the 2017-18 season and was named the Man of the Match in his first two matches, taking nine and eight wickets against Kerala and Haryana respectively. He currently has 29 wickets from five first-class matches and three scalps from as many one-day matches.
Atharwa Taide, also picked in both squads, was the captain of the Vidarbha Under-19 team that won the Cooch Behar Trophy earlier this year. He led them to their maiden title with a marathon knock of 320 off 483 balls in the final against Madhya Pradesh.
