WATCH | Three balls to go ... SA speedster Ismail strikes with hat-trick to seal Welsh Fire win

Former Proteas women's pace bowler Shabnim Ismail lit up The Hundred with the tournament's third-ever hat trick on Thursday.

Playing for the Welsh Fire in their round-robin game against the Birmingham Phoenix at Edgbaston, the travelling side was defending 137.

With four runs required off three balls, the South African speedster, who had to defend nine from the last over and had conceded five from the first two balls, prised out Tess Flintoff (55), Erin Burns (0) and Issy Wong (0) to collect a remarkable win for the Welsh team.

The hat-trick not only sealed a three-run win, but also kept the Welsh Fire at the top of the women's Hundred table with three wins from four matches.

Ismail joins Imran Tahir and Alana King as the tournament's only hat-trick aces.
