Pooja Vastrakar bowled a sharp and incisive spell to take the Indian women's cricket team to their maiden Asian Games final, crushing Bangladesh by eight wickets in a lopsided semi-final here on Sunday.

Right-arm seamer Vastrakar, who replaced Anjali Sarvani in the squad just before leaving India, had career-best figures of 4/17 in four overs as Bangladesh were bowled out for 51 in 17.5 overs — their lowest-ever T20 score against the neighbours.

India will face Sri Lanka in the final on Monday. The Lankans defeated defending champions Pakistan, who had won the gold at Incheon Games 2014, by six wickets in the other semi-final.

The chase of 52 was a cakewalk as it was achieved in only 8.2 overs. Kanika Ahuja (1 not out) and Jemimah Rodrigues (20 not out) took India home despite losing skipper Smriti Mandhana (7) and Shafali (17) cheaply.

India once again played without regular skipper Harmanpreet Kaur, who is serving a two-match suspension. She is likely to play the final.

Brief scores: Bangladesh 51 in 17.5 ovs (Pooja Vastrakar 4/17). India 52/2 in 8.2 ovs. India won by 8 wkts.
