2018–19 Brisbane Heat WBBL season

Responding to the Sydney Thunder's first innings total of 7/171, Heat opener Beth Mooney recorded her maiden WBBL century but was then dismissed in the 17th over. With Brisbane still requiring 19 runs off the last twelve balls, Harmanpreet Kaur—having already claimed two wickets, including the stumping of Mooney, for just ten runs—came on to bowl her third over. The Heat, primarily through Delissa Kimmince, scored 13 runs off the over to swing the momentum once more. Laura Harris then hit the winning runs against the bowling of Nicola Carey with three wickets in hand and three balls remaining, making it Brisbane's highest successful run chase. The result helped to set up a semi-final encounter between the two teams on the following weekend.[10][11][12]

The lower-ranked Heat posted a first innings total of 7/140, recovering from 5/78 after 12 overs through an unbeaten knock of 32 from 25 by Laura Harris. After struggling through the middle overs of the run chase, a late charge by the Sydney Thunder brought the hosts back into the contest to leave a required five runs off the final delivery for victory. The last ball, sent down by spinner Jess Jonassen, was struck flat and cleanly to deep square leg by batter Nicola Carey. Jonassen immediately signalled disappointment as the ball set sail for beyond the boundary rope, therefore scoring six runs and clinching the match for Sydney... However, Brisbane fielder Haidee Birkett made enough ground in time to take a "miracle"[1] catch just inside the field of play to knock the Thunder out of the tournament.[13] The match, in conjunction with the other semi-final played later in the day, was hailed as a showcase of "the irrefutable rise of women's cricket"[14] and "sport with drama, skill and unpredictability – a potent recipe for success".[15]

In front of the league's first-ever sellout crowd,[16] the visiting Heat pulled off an upset victory to win their maiden championship and deny a Sydney Sixers three-peat. Requiring 34 runs with 36 balls remaining, Brisbane looked to be in control of the chase until the 15th over when Sydney leg spinner Dane van Niekerk struck twice—including the removal of linchpin Beth Mooney for 65 through a forward-diving catch by Ellyse Perry in the outfield. Although the Heat would continue to lose wickets, Laura Harris did enough to steady the ship, eventually hitting the winning runs with three wickets and four deliveries to spare.[17] Player of the Final Mooney, who had been receiving on-field medical treatment for the flu and heat stroke, revealed in a post-match interview that her ongoing game delays instigated sledging from several opponents: "It was kind of nice to know while I wasn't feeling well, I was going well enough to piss them off and they were getting frustrated at how long I was taking to face up... I've played enough cricket against (the Sixers) to know what gets under their skin and we definitely won that battle."[18]
