5 instances when Bangladesh lost a match off the last ball 

#3 Final game of the 2018 series against Afghanistan

Bangladesh whitewashed by Afghanistan in three-match T20 series

After losing first two matches of three-match series against Afghanistan earlier this year, Bangladesh looked eager to avoid a shameful whitewash on the third encounter. But, they failed to skip the inevitable.

Afghanistan posted 145 on the board batting first. The Tigers failed to chase it down. They needed 30 in the last 12 balls. Mushfiqur hit Karim Janat on the 19th over for five consecutive fours, and Bangladesh needed only nine in the closing over.

Rashid Khan came to bowl the 20th over and dismissed Mushfiqur in the first delivery, subsequently, Bangladesh lost the match by one run. Ariful Haque failed to manage two from the last ball. And thus, Bangladesh whitewashed by Afghanistan for the first time in their history.
