In the first pre-quarter-final, Mumbai took on the Plate group toppers Sikkim. Despite losing the openers early, skipper Aachal Valanju and Sanika Chalke built a partnership. Valanju was retired hurt for 49 runs from 48 balls, but Chalke kept the innings going alongside Tushi Shah.
The duo took the team past the 250-run mark, with Chalke finishing with an unbeaten century. Though Shah got out for an 83-ball 77, Chalke scored 105 from 116 balls, taking Mumbai to 292 for three in 50 overs.
Chasing almost six runs per over, Sikkim crumbled under pressure. Barring the 84-ball 26 from Pranita C, no one crossed 20 runs. They were eventually all out for 84 in 39 overs. Savesharvi Suhas was the star with the ball, taking four for 11 in her eight overs.
Meanwhile, Bengal, which finished second in Elite Group B, was stumped by the clinical bowling performance from Karnataka. Three-fers from Pooja Kumar M, Nirmitha C J, Savi C S meant that the Southern state that finished second in Elite Group E dismissed Bengal for 69 in 26.4 overs.
Despite losing some early wickets, Karnataka captain Chandasi KC took them across the line in 34.2 overs.
In the third and final pre-quarter-final, K E Dayana's half-century and the unbeaten 45 from K Mahanthi Sree helped Andhra scrap their way to 180 for seven in 50 overs, countering a comprehensive bowling performance from Haryana. Gulshan Ali was the pick of the bowlers, taking four wickets for 31 runs in her ten overs.
Chasing almost four runs per over, Neha Sharma scored a valiant fifty in vain as Haryana fell short by 19 runs. N R Shree Charani starred with the ball for Andhra as she took three for 25, helping her team seal a spot in the quarter-finals.
