Sixers secure spot at top of table

The Sydney Sixers are well on track to defend their Rebel WBBL title after securing top spot with a comprehensive seven-wicket triumph over the Adelaide Strikers.

For the second time in as many days, the Sixers trumped the Strikers - largely through the efforts of comeback queen Sarah Coyte with the ball and Alyssa Healy with the bat - to stroll to victory with 11 balls remaining.

Fresh off a blazing 106 on Saturday, national wicketkeeper Healy thumped 63 before departing with the finish line in sight, piloting the Sixers' 3-112 chase.

Captain Ellyse Perry became the only WBBL batter to reach the 500-run mark this summer before holing out for 13.

But Healy continued on her merry way, belting the Adelaide attack to all corners of Hurstville Oval.

Earlier, Coyte snared 3-18 off her four overs, including the key scalp of Strikers top-scorer Tammy Beaumont (28).

Coyte's tight bowling was pivotal in restricting the Strikers to just 9-111 off their 20 overs, which was never going to be enough, given Healy's ravenous late-season form.

In her two games back since coming out of retirement, Coyte has put together the remarkable figures of 5-32 off eight overs.

She now looms as the key bowler for the Sixers, who enter the semi-finals with five consecutive wins under their belt.

The Strikers, with three losses from their last four games, slipped to fourth position with an 8-6 record after a weekend that didn't go their way - but the will still make their first-ever finals appearance after Brisbane Heat's loss to the Sydney Thunder.
