Baig took no further part in the match after breaking down during her run-up with what appeared to be an injury to her right calf muscle, which was already heavily taped, and Sana stepped in to complete her over.

Pakistan had already been without Baig at the previous T20 World Cup in South Africa early last year after she fractured her finger shortly before the tournament, but on this occasion Sana said she believed it was just cramp and "she will be okay in the next match".

"When I got the captaincy I decided that I will lead from the front, so that's the main thing I did today," Sana said. "Unfortunately we got the early injury, I was under pressure at that time but and Muneeba [Ali] and Nida [Dar] told me that you have to come and do your work and so that's the main thing because our whole team is banking on it."

At the age of just 22, Sana took over from Dar as captain in August. This was just her fourth T20 match in charge.

"I would like to congratulate Pakistan captain, Fatima Sana," Athapaththu said during the post-match presentation. "She played really good cricket and she is always leading from the front."

Meanwhile, 'who else besides Athapaththu?' has been a question following Sri Lanka around for a while now, their skipper enjoying an extended streak of form dating back to mid-2023. Since her unbeaten 80 off 47 balls against New Zealand in Colombo in July last year, Athapaththu has scored 928 runs in T20Is at an average of 44.19 and strike rate of 136.47, compared to her career strike rate of 110.77.

Athapaththu took a wicket in the powerplay and two more in as many balls as Pakistan stared down the prospect of being bowled out inside their 20 overs. They reached the end but only just as Udeshika Prabodhani - who also finished with three wickets - removed Sadia, caught by Gunaratne at mid-off, with the last ball of the innings.

When Athapaththu effortlessly scythed Sadia's third ball to the boundary through point, Sri Lanka fans could have been forgiven for thinking victory would be swift. But that feeling fell away in the third over of the run-chase when Sana struck, luring Athapaththu to attempt a lofted drive which went straight to extra cover.

As Sri Lanka wickets steadily tumbled - only Nilakshika Silva (22) and opener Vishmi Gunaratne (20 off 34) reached double figures - the run rate never fired and what might have been had Athapaththu stayed in became a question once more.

Vishmi admitted the Sri Lanka batters struggled with the low, slow Sharjah pitch and the lack of pace from Pakistan.

"It wasn't easy to adjust to the conditions," she said. "It was low pitch and they didn't give pace to us and it was very difficult after this."

Both sides will expect to face sterner tests in the coming days. Sri Lanka play defending champions Australia next, back in Sharjah on Saturday, and Pakistan will play India in Dubai on Sunday.
