Sparks knows what is required of her crew this evening.
"I want us to play the hardest defence we can," she said.
"We want to be more aggressive on defence and also make smarter decisions more quickly on offence."
Butter Fingers coach Janelle Te Rauna-Lamont and her team are more than positive ahead of this crunch game.
"We're looking forward to this. We've been working on our shooting and, yes, everybody's available."
Everybody includes Kiara Swannell and Peyton Riri, who put up 20 and 13 points respectively last time out. These two, plus O'Shae Rangihaeata and a dominating figure in Dyani Johnson, could spell trouble for Hoops.
Johnson's height and strength as a defensive rebounder will almost certainly be a major factor in the result of the 2 v 3 semifinal.
Dreamers player-coach Melissa Mackey-Huriwai also wants a big defensive effort from her team, against Brick Layers.as
"We will be looking to play more pressure-defence," said Mackey-Huriwai, who places great stock in the importance of confidence-building with young players such those in her Dreamers team.
The Wilkinson-coached Brick Layers should be of good heart - but for a sublime three-point shot from Peyton Riri, one of the most well-performed GBA/club league players of the season, they might have beaten the competition's No.1 crew 52-50.
They have skilful guards in Anna Spring, Courtney Stubbins and Jayda Waititi-Leach. Brick Layers have not been outsized or outclassed; they just need more shots to drop.
As it is, if things go their way in Game 1 tonight, they could be grand finalists on January 25.
The draw for tonight at the YMCA is --
1 v 4 semifinal, 5.30pm: Dreamers (1) v Brick Layers (4)
2 v 3 semifinal, 6.45pm: Butter Fingers v Hoops I Did it Again.
