The victory was their first in three years of the Super Netball competition over the Vixens, and they did it in style with a 60-50 scoreline.

The Swifts took maximum points in front of a packed Margaret Court Arena, overpowering the Vixens at every turn to collect a valuable eight points.

Without collecting even a bonus point, the former ladder leaders slipped down to third.

Vixens coach Simone McKinnis said she didn't see their below-par performance coming.

"It was probably one of our better training weeks and I thought they were looking good and feeling good and well prepared but the Swifts are playing very good netball and we just didn't match that," McKinnis said.

Defending champions Sunshine Coast Lightning claimed second spot on the back of a commanding 72-61 win over Giants in their clash at USC Stadium, which was their fourth successive victory.

The Lightning trailed the Giants at halftime but set up the win with a stunning 25 goals in the third quarter with Peace Proscovia (43 goals from 48 attempts) helping herself to 20.

In other matches, West Coast Fever claimed their first win of the season with a 63-61 scoreline against Collingwood in Bendigo.

Adelaide cracked their first win since round one when they held off the Queensland Firebirds for a 54-51 victory at Priceline Stadium.

Already missing star shooter Romelda Aiken with an ankle problem, the winless Firebirds lost centre Mahalia Cassidy early in the match with what appeared to be a serious knee injury.
