Senior batter Nicole Bolton recorded another unbeaten match-defining innings to today steer the Alcohol.Think Again Western Fury to a seven-wicket win over Tasmania Roar and launch Western Australia to the top of the Women's National Cricket League table.

Bolton was pivotal and ended her knock on 93 not out at Adelaide Oval No.2 to ensure WA chased down Tasmania's 222 with relative ease, finishing 3-225 with more than 11 overs to spare.

The performance added to the national top-order batter's 125 not out against South Australia yesterday, leaving her unbeaten for 218 runs in two games.

The win moved WA to the top of the 50-over WNCL table, with two wins from its two matches, but with fellow unbeaten sides New South Wales and ACT yet to play their second games of the opening round.

Tasmania won the toss and elected to bat on a deck that yesterday produced more than 600 runs in WA's win over South Australia.

However, the Fury attack had the Roar under pressure from the outset.

England import Kate Cross (3-26) combined with Piepa Cleary to limit Tasmania's flow early, with just one boundary in the first five overs.

The stranglehold paid dividends on the first ball of Cross' third over, bowling Laura Wright for two before the international had Corinne Hall caught a short time later for seven, with Tasmania 2-19.

The Roar's Georgia Redmayne (89) led a revival and had her side approaching the 100 without further loss, before another batting stumble.

All-rounder Heather Graham (4-52) tore through the dangerous middle order and had Tasmania 8-191 with her fourth wicket - the dismissal of Redmayne.

Cross and Teneale Peschel (2-28) finished off the tail-enders to bowl Tasmania out for 222, with just three balls remaining in the innings.

The Fury entered their chase with purpose, as Chloe Piparo (56) launched to her half-century and, alongside the mature Bolton, moved WA past the team ton without loss.

However, a short time later Piparo was gone, caught at backwards point attempting to cut Courtney Webb (2-24).

Webb then had WA's heart skip a beat as she had Game 1 record-breaker and Fury captain Elyse Villani caught for just 10, before the Roar wrested control of the momentum, with Graham caught and bowled for two by Erin Fazackerley.

It meant WA had gone from more than 100 without loss, to be 3-135 having lost 3-24.

The Fury required some calming heads and they found them in Bolton and England's Amy Jones (44 not out) and, together, the pair put on the remaining 88 required for victory.

WA next plays NSW and ACT when it hosts Round 2 at the end of November.
