Sam Billings leads Sydney Thunder to the Big Bash final with a four-wicket victory against city rivals Sydney Sixers in the Challenger.

Sydney Thunder have booked their berth in the Big Bash League (BBL) final, following a nail-biting four-wicket win over Sydney Sixers. The win paves the way for David Warner to guide his team to their first BBL title in nine years. Notably, it has been a remarkable turnaround for the Thunder, who finished last in the previous season.

Sam Billings says the third umpire erred in a crucial moment of the Sydney derby BBL final that the Thunder won by four wickets.
