India's Shafali Verma and Smriti Mandhana set multiple records in the one-off Test against South Africa, with Shafali scoring the fastest double century in women's Test cricket history. Verma's 205 off 194 balls and Mandhana's 149 off 161 balls led to a record-breaking 292-run opening partnership, surpassing the previous highest of 241 runs. India's total of 525 for 4 by the end of Day 1 is the highest ever in a single day in Test history, breaking an 89-year-old record. Shafali's innings included 23 fours and 8 sixes, making her only the second Indian woman after Mithali Raj to achieve a double century in Test cricket. The 20-year-old's remarkable performance has set a new benchmark in aggressive batting, while India's dominant position leaves them in control of the Test.
