In a morning session mostly curtailed by rain, the visitors Afghanistan managed to take stretch lead to 398 against Bangladesh in the one-off Test match at Chattogram.
The last two wickets managed to take the team score from 237 - the overnight score - to 260 as Afsar Zazai held his end up and played some aggressive shots.
He was not out on 48 from 110 balls with three fours and a six as he ran out of partners to bat with.
In reply, Bangladesh reached 30 for no loss with a new opening pair for Shadman Islam and Liton Das - who was promoted up the order in place of Soumya Sarkar - to create a left-right combination.
Shadman looked impressive so far in his innings scoring 21 runs off 27 balls with three fours while Liton has held his end up scoring nine off 27 deliveries.
Bangladesh still need 368 runs to win with five sessions in hand, if there are no further rain interruptions.
