The Scorchers take on the Hurricanes at the #TheFurnace on Saturday and at Lilac Hill on Sunday.
MacDonald said the bowlers would again need to be on top of their games, following a solid bowling display in their double header in Alice Springs last weekend, in which they held the Strikers to 88 and 107.
“I think the bowlers have gotten better as the tournament has gone on and we’re just trying to work on our strengths this week at training and stick to our processes and hopefully that will help us get the job done on the weekend,” MacDonald said.
“Having Katherine Brunt in our side has been great, she’s probably one of the best bowlers in the world at this format and she’s had a great tournament.
“I think spin has been good for us as well, Emma King was very good early on and is still having a great tournament.
“Nicole Bolton has come through in probably the last half a dozen games and has been really important for us, especially in the power play.
“The Hurricanes will have a bit of confidence after their win against the Renegades, we know they can be dangerous and they’ve got some good players so we have to plan well and execute our strengths.”
The Hurricanes, who are currently at the bottom of the WBBL ladder, recorded their first win of the season earlier this week, defeating the Melbourne Renegades by four runs.
The Scorchers are currently sitting in sixth position after their two losses against the Strikers in Alice Springs.
Saturday’s game between the Scorchers and Hurricanes gets underway at 1.30pm WST while Sunday’s match will start at 2.00pm WST.
