McDonald contributed strongly once again yesterday, defeating Tasman counterpart Aroha Minhinnick 1-up after faltering a little at the death.
“I was 3-up with three to play,” she said.
“I lost the next two with bogeys, but parred the last to win.”
The pressure had been lifted a little by No.3 Martha Manaena (7 and 5), No.4 Clare Choi (4 and 2) and No.5 Aseri Miekle (6 and 4) having already sealed the team win.
McDonald’s win gave her a four-win/two-loss record, her best performance as a No.1 at the national interprovincials.
