Rahmanullah Gurbaz and Ibrahim Zadran hit hundreds as Afghanistan clinched a 142 run victory over Bangladesh to seal their three-match one-day international series.

Bangladesh attempted to put a strange week behind them after captain Tamim Iqbal shocked his teammates by announcing his immediate retirement on Thursday and then reversing his decision the following day.

With their 256-run stand in Chittagong, Afghanistan’s openers laid the foundation for a mammoth total of 331-9, a record ODI partnership for the tourists.

“Obviously very happy with how it’s going, the way they played the shots,” Afghanistan coach Jonathan Trott told reporters.

“We were going to bat first as well, having looked at the weather… The way they played, it’s natural.”

Afghanistan bowled out Bangladesh for 189 in 44 overs with the help of Fazalhaq Farooqi’s 3-22 and Mujeeb Ur Rahman’s 3-40.

Afghanistan becomes the second team in the past seven years to win an ODI series in Bangladesh, following world champion England.

Mushfiqur Rahim scored 69 runs to lead the hosts after they were reduced to 72-6, with some assistance from Mehidy Hasan in an 87-run seventh wicket partnership.

Mujeeb Ur Rahman dismissed Mehidy for 25 points, leaving too much work for Mushfiqur.

Mushfiqur holed out to Mujeeb at deep square leg off Farooqi, ending the match as Ebadot Hossain was unable to bat as the last man.

Bangladesh, who were defeated by 17 runs in the first match on Wednesday, elected to bowl first after stand-in captain Litton Das won the toss.

On a green surface, the hosts struggled to make breakthroughs, and by the time Shakib Al Hasan had Gurbaz leg-before, Afghanistan had already surpassed their previous best score against Bangladesh of 306-4.

Gurbaz scored his fourth ODI century by smashing 145 off 125 deliveries with 13 fours and eight sixes.

Ebadot dismissed Rahmat Shah (two) and Mehidy removed Hasmatullah Shahidi (two) and Najibullah Zadran (ten) in quick succession.

Bangladesh’s Shakib, Mehidy, Mustafizur, and Hasan Mahmud each took two wickets.

Ibrahim was dismissed by Mustafizur for 100 off 119 deliveries.

“One series can always go bad,” Mehidy said.

“But in the recent past, we played much better cricket.”

The day after Bangladesh’s narrow loss in the series opener, Tamim announced his retirement in an emotional press conference on Thursday.

However, after meeting with Prime Minister Sheikh Hasina on Friday, he withdrew his resignation, citing orders to do so.

Instead, he will take a six-week leave of absence and return for the Asia Cup.

On July 11, the third and final match of the series will be played at the same venue.
