The Women's Asia Cup Twenty20 tournament hadn't been a happy one for the two associate sides - Thailand and hosts Malaysia - with comprehensive defeats par for the course.

But that all changed today as Thailand secured a historic win over Sri Lanka, the first by Thailand in either men's or women's cricket.

Thailand captain Sornnarin Tippoch won the toss at the Royal Selangor Club and chose to put her opponents in to bat. Openers Yasoda Mendis and Anushka Sanjeewani scored 22 and 32 respectively, and number 8 Oshadi Ranasinghe scored 20 from 18 balls, but no other Sri Lankan was able to reach double figures.

Off-spinner Wongpaka Liengprasert was the pick of the bowlers for Thailand, taking 5-12 as Sri Lanka were bowled out for 104, the last wicket falling when Inoka Ranaweera was run out from the last ball of the innings.

Thailand started their run chase well with the opening pair of Nattakan Chantam and Naruemol Chaiwai putting on 43 before the former was out for 15. Chaiwai took her score to 43 before she was the second wicket to fall, caught by Nilakshi de Silva off her own bowling.

Chaiwai's wicket fell from the first ball of the 16th over, with 28 runs still needed from 29 balls. Thailand rotated the strike, got boundaries when possible, and whilst they lost wickets, got themselves into a position where they needed six from the final over.

Captain Tippoch was stumped from the first ball of that over - and of her innings - but Suleeporn Laomi and Wongpaka Liengprasert were able to get the six runs needed, helped by three byes, to secure a famous four wicket win.

Thailand's win wasn't enough to lift them ahead of Sri Lanka on net run rate and they finish in fifth place for the tournament. The win will no doubt give them confidence as they prepare for the Women's World Twenty20 in the Netherlands next month, where they're likely to be amongst the favourites.
