The Afghans fell agonisingly short of a major upset after restricting India to their lowest total of the tournament, 224-8 on a slow track.
But a spirited Afghanistan, who moved on their huge loss to England in the last game, rode Mohammed Nabi's 2/33 and wickets each for Mujeeb Ur Rahman (1/26), Rashid Khan (1/38) and Rahmat Shah (1/22) to keep the run-flow in check throughout the innings.
Afghanistan after being pounded by England, managed to come back in the big game against tournament favourites India. "In the end as well, the communication was to finish him off at 49 so that Shami can have enough runs to defend in the last over and the plan worked out well today".
There were numerous moments during Afghanistan's chase of 225 where Indian skipper Virat Kohli was seen getting animated, anxious and even arguing with umpires in desperation of getting wickets in Southampton.
Shami conceded a boundary off the first ball of the final over but struck with his third, fourth and fifth deliveries to finish with 4-40.

And he made one thing clear: Don't compare him to National Basketball Association players who came before him. Memphis is set to draft point guard Ja Morant with the second overall pick on Thursday evening.
Kohli also praised man-of-the-match Jasprit Bumrah for his impressive bowling display that brought India back into the contest. The team batted 34 overs of spin bowling and scored 119 runs, he added.
Shami's brother, Mohammed Kaif, said the mood in his local village is jubilant as everyone is in a celebratory spirit and hopes that their boy continues to perform in the same manner in ICC World Cup 2019.
Speaking after the toss, Kohli said it looks "like a really good wicket", and so does the weather for the game.
"It gives us healthy competition in the side", Bumrah said. "I don't think anyone expected such a close match but it's great for the World Cup and probably a good thing for India as well because it's a kind of shock treatment that means they won't take anything for granted moving forward", he wrote. "A team like Afghanistan who have a lot of talent doesn't let you play the way you want to play".
