Radha Yadav (3/24) ran through Bangladesh's top order after Richa Ghosh's quickfire unbeaten 28 off 17 balls, setting up India's 21–run win in the fifth T20I and a 5-0 series sweep at Sylhet. Chasing a huge 157-run target, Bangladesh began promisingly but collapsed against the left-arm spinner Yadav. Despite the rearguard act by Ritu Moni (37) and Shorifa Khatun (28 not out), the hosts finished at 135 for six in 20 overs.
All-rounder Moni and Shorifa put on a resolute stand of 57 runs for the sixth wicket to lead the fightback and put India in pressure, but the visitors prevailed eventually. It was leg-spinner Asha Sobhana (2/25) who broke the resilient partnership, cleaning up Moni in the 17th over to shut the doors on the home side.
Bangladesh were left reeling at 52 for five halfway through but Moni and Shorifa reignited their hopes, cashing in on every opportunity to score boundaries and with deft rotation of strike. Yadav made her first impression in the game with an athletic catch to get rid of an on-song Sobhana Mostary (13) off Titas Sadhu. Mostary had hit three fours off Pooja Vastrakar's first over to set her side on track during the chase.
After getting Dilara Akter (4), caught at mid-off by Vastrakar for her first breakthrough off her first ball, Yadav cleaned up Bangladesh skipper Nigar Sultana (7) and pinned Rubya Haider (20) in the front of the stumps for two wickets in the ninth over.
