Rain forced an early tea in Mirpur on Friday, with Bangladesh 34 for four after 13 overs, leading West Indies by 61.

Roston Chase, the visiting captain, had taken three for six in four overs, wrecking the top order with his off-spin.

Drizzle arrived soon after Chase trapped Najmul Hossain Shanto lbw in the 13th over. The Bangladesh captain failed to get in line while playing for turn, and a review confirmed the ball would have hit leg stump. He made 10 from 37 balls.

Mominul Haque, hurt in the head while fielding earlier, has been ruled out of the Test with concussion. Jaker Ali replaced him, walking in at number six. Under new ICC regulations, a seven-day stand-down means he will miss the next match too.

Towhid Hridoy then added to the damage. After defending his first ball, he swung needlessly at the next and picked out Jayden Seales at mid-on, handing Chase two wickets in one over and leaving Bangladesh 28 for three. It was reckless, with Mominul unavailable.

Chase had started the over by bowling Shadman Islam, who failed to get in line and brought his bat down late. Shadman made 13 from 30 balls with two fours, ending a start that had taken Bangladesh past 25 with only Tanzid lost.

Tanzid Hasan fell for a duck to Shamar Joseph in the second over, closing his bat face early and edging a leg-side flick to Chase at gully. Shanto came in at three and, with Shadman, lifted the lead beyond 50 by the eighth over.

Nayeem Hasan’s four for 33 had earlier bowled West Indies out for 245, giving Bangladesh a 27-run advantage. Chase finished unbeaten on 43, and with the ball he has now taken the top order apart, shifting the balance of the session.
