A third win of the tournament keeps Afghanistan in contention for their first Cricket World Cup semifinal.

Afghanistan have defeated Sri Lanka by seven wickets in Pune to record their third win of the Cricket World Cup and boost their hopes of a semifinal place.

Their bowlers had laid the foundation of their third win in six matches on Monday when they bowled out Sri Lanka for a below-par 241 in 49.3 overs.

Three of their top five batters, including Hashmatullah Shahidi, then produced half-centuries in a clinical chase that they accomplished in 45.2 overs to move to fifth place in the points table.

Azmatullah Omarzai (73) scored the winning run with Shahidi (58) looking on from the other end.

Shahidi and his men had stunned holders England and 1992 champions Pakistan earlier in the competition, and they proved those were no flukes with yet another impressive display against 1996 winners Sri Lanka.

Put into bat, several Sri Lankan batters got their eyes in but could not quite capitalise on those starts.

After the fall of Dimuth Karunaratne in the sixth over, Kusal Mendis (39) forged half-century partnerships with Pathum Nissanka (46) and Sadeera Samarawickrama (36) to steady the innings.

At 134-2 in the 28th over, Sri Lanka looked well placed to reach the 275 mark, but the plucky Afghans struck at regular intervals to peg them back.

Angelo Mathews and Maheesh Theekshana raised 45 quick runs for the eighth wicket, but Sri Lanka still fell short of the 250 mark.

Afghanistan lost Rahmanullah Gurbaz in the first over, but Rahmat Shah (62) and Ibrahim Zadran (39) calmed the nerves with a 73-run partnership.

Kasun Rajitha dismissed Shah, but not before the batter had brought up his second successive fifty of the tournament.

Shahidi and Omarzai mixed caution with occasional aggression in their unbroken century stand to take Afghanistan closer to the target.

With victory in sight, both decided to play their shots, and Omarzai scored the winning run when he attempted to hit a six and was dropped at deep mid-wicket.

“Quite happy and proud of the team,” Shahidi said after the match.

“The chase was very professional and I am very happy about it.”

Sri Lanka captain Mendis rued his side’s poor total after their fourth loss in six matches.

“I think we were a little bit short of runs,” he said.

“We needed 280 or 300 on this pitch. I think the bowlers did well in the first 10 overs, but it was tough after that.”
