Brisbane Heat clinched their second Big Bash League (BBL) title after beating Sydney Sixers by 54-run in the final match of the 2023 edition on Wednesday.

Brisbane posted a challenging 166-8 in 20 overs before routing Sydney for 112 off 17.3 overs in front of a sell-out crowd of 43,153 at the Sydney Cricket Ground.

Brisbane paceman Spencer Johnson, who bagged 4-26, was named man of the match. 

Brisbane opener Josh Brown clubbed 53 off just 38 balls and Matt Renshaw smashed 40 off 22 balls to set up a competitive total batting first.

Brown clubbed three sixes and five fours in his half-century before he was out lbw to veteran spinner Steve O'Keefe.

Renshaw played a key cameo in his quickfire knock with the powerplay proving to be expensive for Sydney, as they conceded 31 runs off it.

Sydney came back strongly as paceman Sean Abbott picked three wickets in his final over to end with four for 32.

O'Keefe, 39, playing in his final match for Sydney, finished with 99 BBL career wickets, bowling tidily to deliver figures of 1-26 off four overs.

Brisbane’s quality set of bowlers demolished Sydney before their fans with Johnson's four wickets, backed by leg-spinner Mitchell Swepson's two for 19 and Xavier Bartlett's two for 12.

Skipper Moises Henriques top-scored with 25 off 27 balls for and wicketkeeper Josh Philippe chipped in with 23 (22).

Brisbane’s Michael Neser participated in the catch of the final when he caught Sean Abbott (16) at long-on and managed to somehow flick the ball up to his teammate Paul Walter before he fell over the boundary rope to effect the catch.

Sydney were never able to string together any substantial partnerships and the match was effectively over midway through their innings.
