A BCB Under-16 team drew the second three-day game against a Mumbai Under-16 side at the Sachin Tendulkar Gymkhana ground in Mumbai on Friday, with the result enough to see them clinch the two-match series.
Sheikh Imtiaz Shihab picked up five wickets as Mumbai were bowled out for 214 in their first innings.
In reply, Bangladesh took a first-innings lead after posting 234. Kalam Siddiki smashed a century while Rifat Beg scored 45 runs for the visitors.
In their second innings, Mumbai posted 305 on the third and final day before officials called it a day and the game ended in a draw.
Bangladesh had won the prior three-day game by an innings and 174 runs.
The visitors will play the first of the three-match one-day series on May 8 at the same venue.
