SYDNEY, Australia (CMC) — Stafanie Taylor’s season-best half-century was nearly in vain but somehow Sydney Thunder managed to hang on and beat city rivals Sydney Sixers in a dramatic Women’s Big Bash League encounter here Saturday.

Set 139 for victory at the Sydney Cricket Ground, Thunder were propelled by Taylor’s top score of 68 off 51 balls but once she departed to the second ball of the penultimate over with 11 runs required, Sixers hit back to ensure scores were level at the end of the allotted overs.

There was even more drama in the one-over eliminator as Taylor helped Thunder to reach eight for one and Sixers then lost three wickets as they too ended on eight runs.

Boundary count was then used to determine the winner and Thunder, with 16, edged out their opponents who struck 14.

The victory left Thunder three from bottom in the eight-team tables on 10 points while Sixers remained top on 16 points.

Thunder’s run chase begun shakily when they lost Rachael Haynes cheaply for eight with the score on 14 in the third over but Taylor and captain Alex Blackwell (19) seemed to be reviving the innings in a 29-run, second-wicket stand.

Against the run of play, however, Blackwell cut an innocuous delivery from seamer Kim Garth to point in the seventh over, leaving Taylor to rally the innings.

The West Indies captain responded well, adding 41 for the third wicket with Indian star Harmanpreet Kaur (16) and a further 23 for the fourth wicket with Nicola Carey (8).

Taylor struck seven fours and two sixes before becoming one of two Sarah Aley’s wickets, caught at the wicket with victory in sight.

Earlier, the 25-year-old Jamaican had produced a brilliant spell with her off-spin to claim two for 15 from three overs as Sixers, opting to bat first, mustered 138 for seven off their 20 overs.

Ashleigh Garner top-scored with 54 off 41 balls while Sara McGlashan chipped in with 30 from 31 deliveries.
