Pakistan captain Sana scored 50 off 15 balls in a match-winning innings against Zimbabwe in Karachi. Pakistan’s Fatima Sana has broken the world record for the fastest half-century in women’s T20 international cricket with a 15-ball 50 against Zimbabwe. Playing at home at the National Stadium in Karachi, the all-rounder top-scored with 62 runs off 19 balls as Pakistan beat the visitors by 133 runs and sealed the series 3-0. Sana broke the record of an 18-ball half-century jointly held by Sophie Devine of New Zealand, Phoebe Litchfield of Australia and India’s Richa Ghosh. The captain let loose from the first delivery of her innings, scoring a boundary past point, as Pakistan chose to bat first. Hitting 10 fours and two sixes, she took apart the Zimbabwean pace attack in an innings that was played at a strike rate of 326. Predictably named player of the match, Sana helped Pakistan post 223-4 in 20 overs and took one wicket as Zimbabwe were bowled out for 90 runs in 17.1 overs.…
