Spinners Rashid Khan and Zahir Khan shared five wickets between them as Afghanistan came within four wickets of a historic win over Bangladesh in the one-off Test in Chittagong on Sunday.

The visitors — playing only their third Test ever — reduced Bangladesh to 136-6 before rain forced early stumps on the fourth day, with the hosts, who were set a record target of 398 runs, still needing 262.

The highest successful run chase in Bangladesh is 317-7 by New Zealand at the same ground in 2008.

“Yes, we are bit excited because we are in a good position,” Afghanistan’s wicketkeeper-batsman Afsar Zazai said.

“It means a lot to be honest,” he added.

“The people know about us good enough in white-ball cricket. We’ve discussed in our dressing room that this Test match is very important for us to win because we want to show we can play Test cricket.”

Skipper Shakib Al Hasan remained unbeaten on 39 runs, giving a little hope to Bangladesh amid the gloom at the Zahur Ahmed Stadium, where rain interrupted play in all three sessions much to Afghanistan’s frustration.

Shakib will resume the fifth day’s play along with Soumya Sarkar, the last recognised batsman for Bangladesh, who was yet to open his account.

Shakib seemed to be preparing for a loss.

“The realistic result is we are very close to defeat. Unless there is some rain... Probably we are losing,” he said.

Rashid, who made his debut as youngest-ever Test captain, led Afghanistan from the front, finishing the day with 3-46 while left-arm chinaman Zahir claimed 2-36 runs.

Retiring all-rounder Mohammad Nabi claimed the other wicket.

Earlier, resuming at 237-8 after more than two hours’ delay due to drizzle, Afghanistan added 23 runs to their overnight score before they were all out for 260, which took their lead close to the 400-run mark.

Yamin Ahmadzai was run out for nine and off-spinner Mehidy Hasan removed last man Zahir, leaving Zazai stranded on 48.
