Perth Scorchers have successfully defended their Big Bash League title in a gripping final against Sydney Sixers.

The Scorchers needed just one run from the final three balls after matching the Sixers' score of 147.

Brett Lee, playing in his final match before retirement, took two wickets in two balls to dispose of Nathan Coulter-Nile and Sam Whiteman and move the Sixers to the brink of victory.

With Lee on his hat-trick, Yasir Arafat should have been run out after attempting a weak single, but a mix up saw Sixers captain Moises Henriques fumble and allow England batsman Michael Carberry to get home to snatch victory.

Henriques and Shaun Marsh had earlier led the Sixers' assault for the title, hitting 78 and 73 respectively before the dramatic conclusion.

"It's an unbelievable feeling and an unbelievable finish," Scorchers captain Adam Voges said post-match. "We don't make things easy for ourselves but, credit to Binga [Lee], he bowled beautifully.

"We just did enough, which is what we've done all year."

Thirty-eight-year-old Lee said: "That's cricket. We could have had it there. On this night, they were better than us. I tried to block out any other factors and blast those peaks one last time.

"Someone has to lose. Unfortunately that was us."
