Welsh Fire might have lost captain Sophie Devine to injury but their young talent stepped up in a dramatic final-ball victory over Hundred leaders Southern Brave. Set a target of 122 in Cardiff, Heather Graham helped Fire to a four-wicket victory to inflict a first defeat of the campaign on the Brave. "To come in for her first ever Hundred game and hit the ball so cleanly was phenomenal," said Australia all-rounder Graham. The Somerset all-rounder held her nerve with a swift 12 before Graham secured the win with a single off the final ball. Australian international Graham hopes defeating the leaders in dramatic fashion can boost their bid to reach the play-offs for a third time.
