Abu Dhabi, United Arab Emirates: Pakistan kept their Asia Cup campaign alive with a hard-fought five-wicket win over Sri Lanka in a Super Four clash in Abu Dhabi on Tuesday.

With both teams having lost their opening fixtures of the second round, defeat wasn't an option and Pakistan's bowlers rose to the occasion tying Sri Lanka down to 133-8 on a featherbed of a pitch.

Chasing what looked a modest target, Pakistan made heavy weather of it. After a brisk opening stand of 45, their innings went into free fall at 80-5.

But a cool-headed 58-run partnership off 41 balls for the sixth wicket between Mohammad Nawaz and Hussain Talat steadied the ship and saw them home with 12 deliveries in hand.

Nawaz struck a breezy 38 off 24 balls, while Talat anchored the innings with an unbeaten 32 off 30.

Earlier, Shaheen Shah Afridi set the tone with the new ball, nipping out Sri Lanka's in-form openers inside his first two overs.

The left-arm quick returned at the death to dismiss top-scorer Kamindu Mendis and closed with figures of three for 28 -- a spell that put Pakistan on the front foot.

Talat and Haris Rauf chipped in with two wickets apiece, while leggie Abrar Ahmed bowled with miserly precision, giving away just eight runs in his four overs and dismissing fellow leg-spinner Wanindu Hasaranga.

Sri Lanka, unbeaten in the first round with three wins on the trot, have hit a brick wall in the Super Four, losing to Bangladesh on Saturday and now to Pakistan.

With only India left to play, their chances of making the final are hanging by a thread.

Put in to bat, Sri Lanka slumped to 58-5 and looked set to be bundled out inside 20 overs.

But Kamindu Mendis dug in, compiling a fighting 50 off 44 balls with three fours and two sixes, his third half-century in T20Is.

He stitched together a 43-run stand with Chamika Karunaratne for the seventh wicket, but the former champions were still left high and dry.
