India produced a clinical all-round performance to thrash hosts South Africa by 88 runs in the first one-dayer of the ICC Women's Championship at Diamond Oval here today. Opener Smriti Mandhana (84 off 98) scored a strokeful fifty while pace duo of Jhulan Goswami (4\/24) and Shikha Pandey (3\/23) shared seven wickets between them to emerge as the architects of India's victory. Electing to bat, left-handed batswoman Mandhana hit eight boundaries and a six in her 98-ball innings and shared a 99-run stand with skipper Mithali Raj (45) to help India post 213 for seven in their allotted 50 overs. Chasing 214 for a win, South Africa failed to stitch partnerships and kept losing wickets at regular intervals. Skipper D van Niekerk top-scored for South Africa with a 41. Pandey rocked the hosts early by removing opener Lizelle Lee (3), wicket-keeper Trisha Chetty (5) and Mignon du Preez (0) to leave them at 23\/3 in 9.2 overs. Spinner Poonam Yadav (2\/22) then accounted for the other opener Laura Wolvaardt (21), while Goswami trapped Chloe Tryon LBW as South Africa lost half their side in 22.5 overs. Marizanne Kapp (23) and Niekerk tried to resurrect the run chase but Yadav sent the former back to the hut and left-arm spinner Rajeshwari Gayakwad removed the home side skipper after they reached the 100-mark. Goswami then mopped up the tail, dismissing the remaining three batswomen - Ismail (4), A Khaka (2) and M Klaas (1) -to complete the win. Earlier electing to bat, India lost their first wicket when Ayabonga Khaka dismissed opener Punam Raut (19) with Shabnim Ismail taking the catch. Mandhana and Raj then steadied the ship before the opener was removed by Khaka with Sune Luus taking the catch. Next over, Masabata Klaas got rid of Raj as India slipped to 155\/3 in 36.1 overs. South Africa then effected two run outs, dismissing V Krishnamurthy (2) and DB Sharma (6) to further reduce the visitors to 168-5 in 42 overs. H Kaur and wicket-keeper S Verma then added 27 runs before the former was trapped by Kapp in the 48th over. Two balls later, Verma was caught by Khaka off Kapp. Brief Score: India women's team: 213 for 7 in 50 overs (S Mandhana 84; M Kapp 2\/26) South Africa women's team: 125 all out in 43.2 overs (D van Niekerk 41; Jhulan Goswami 4\/24).
