Afghanistan kissed the World T20 goodbye by beating table-toppers West Indies by six runs in a low-scoring thriller.
Asghar Stanikzai had shown his hand when he said they would use spin to restrict West Indies' big hitters on the eve of the match.
Mohammad Nabi and Rashid Khanbacked up their captain's confidence with figures of 2 for 26 each and bowled West Indies out for 117.
West Indies finished as the No. 1 team in Group 1 and will take on either India or Australia in the semi-final, but they will go to Mumbai with a sobering defeat.
They became Afghanistan's second Full Member scalp in the tournament, after Zimbabwe, and the match was another strong reminder that cricket needed to be more inclusive.
West Indies required 40 runs from the last five overs, but Rashid had Denesh Ramdin stumped at the end of the 16th to tip the game off balance. Then it was Afghanistan who had to deal with a blow as fast bowler Hamid Hassan was pulled out of the attack.
He was deemed to have bowled a second hip-high full toss by the square leg umpire, but Andre Russell, the batsman who had been struck by that ball, was rubbing his body below the waist.
Gulbadin Naib finished the over with two dot balls and in the next one, Russell was run out. West Indies needed 25 runs from 12 balls when Carlos Brathwaite thumped Naib for a six over long-off but a ball later, Sammy was caught at deep cover.
Brathwaite freed his arms again and found another six over midwicket and wisely nudged the last ball of the 19th over for a single to retain strike. At the time, West Indies needed 10 runs off six balls.
Nabi began the final over with two dots before Najibullah Zadran, who got them to a competitive score with his unbeaten 48, ran about 20 yards to his left from deep midwicket to complete a superb diving catch to get rid of Brathwaite, West Indies' last dangerman.
With the equation demanding 10 runs off three balls, Andre Fletcher, who left the field in the seventh over with a tweaked hamstring, came out again and could only hobble across for three singles as Afghanistan completed a historic win.
