Set a Duckworth-Lewis target of 251 after the Breakers made 6-246 in 47 overs, the Tigers appeared to have the upper hand at 3-204 when Naomi Stalenberg whacked three consecutive fours in the 39^th over.

But Stalenberg (40 off 35), player of the match Heather Graham (116) and Meg Phillips (4) fell in quick succession as Hannah Darlington's 45^th over swung the game back in the Breakers' favour.

Needing 12 to win off four balls, The Tigers found back-to-back boundaries through Belinda Vakarewa (14), who needed two off Darlington's final delivery to keep Tasmania's winning streak alive.
