Sri Lanka 84 for 2 (Sanjeewani 32, Putthawong 2-21) beat Thailand 78 for 7 (Sutthiruang 31, Priyadharshani 4-10) by eight wickets

Inoshi Priyadharshani's career-best returns of 4 for 10 backed up by a quick 32 from Anushka Sanjeewani helped Sri Lanka brush aside Thailand by eight wickets and advance to the semi-finals of the Asian Games in Hangzhou.

Chasing 79 in the rain-reduced 15-overs-a-side quarter-final, Sri Lanka coasted to a win in 10.5 overs.

Rain and a wet outfield had delayed the start of the game by close to an hour-and-a-half. Once the weather cleared, Sri Lanka opted to field under grey skies.

Udeshika Prabodhani found some movement in the air, but it was Priyadharshani who inflicted the early damage, accounting for four of the first five wickets to fall. She struck twice in her first over - the second of the innings - dismissing Suwanan Khiaoto and Natthakan Chantham. In her next over, she removed Nannapat Koncharoenkai before accounting for Naruemol Chaiwai with a smart caught and bowled.

At 37 for 6, Thailand were sinking rapidly but a 29-run stand between Chanida Sutthiruang and Phannita Maya arrested the slide a touch. Sutthiruang top-scored with an unbeaten 31 and was the only batter to get into double-digits as Thailand managed to reach 78 for 7 in 15 overs.

Chamari Athapaththu and Sanjeewani then made light work of the chase. They brought up their 50 partnership in the sixth over before Thipatcha Putthawong accounted for Athapaththu, who top edged a slog sweep.

Putthawong also removed Sanjeewani but the damage had been done by then. Thailand were not helped by their ground fielding; they committed a number of mis-fields and dropped chances. Harshitha Samarawickrama closed the game in the 11th over with a pull over deep square leg.

Sri Lanka will face Pakistan in the second semi-final on Sunday.
