HBPB No 3 Sara Deam was the only one to halve against Canterbury while No 2 Tessa McDonald, of Gisborne, maintained the best form in the team with a 2 and 1 win over former HBPB veteran Jill Morgan in Waikato colours after a crushing 5 and 4 defeat to Canterbury's Juliana Hung.
Veteran Janie Field, at No 4, ground down Waikato's Zeta Syme 3 and 2.
While it is a little blow to the ego for higher seeds to drop to No 5, McIvor has no qualms about it because that's how everyone performed during their trials.
"We're working the most out of all the other girls so we don't have much time as them.
"Honestly those other girls outplayed me this year."
Besides, McIvor has never played at No 1 and isn't even prepared to accommodate any such thoughts as Angela Jones gallantly remains in the hunt for her first victory against the big guns, after a heavy 5 and 3 loss to Canterbury's Amelia Garvey as well as a 6 and 4 punishment at the hands of Waikato's Chantelle Cassidy in her maiden No 1 ranking.
"Oh my god, I never want to be on the very top. I haven't been No 1 but I know how hard it is there," she said, taking her cap off to McDonald and Deam who have been soldiering on.
McIvor sank her putts yesterday on a rain-punctuated day "and held it together although I didn't play well but I played well enough".
But she put her victory in perspective by disclosing Janphanich was about 12 or 13 years old.
So did she feel like she was bullying the teenager?
"I did feel like I was a little bit," she said but mindful one had to put such emotions aside and do what's best for the collective, especially if it's the biggest upset so far at the tourney.
HBPB have moved up to the fourth rung of division one's standings and are aware Auckland and Canterbury face off this afternoon.
They have a bye this morning and play last-placed winless Otago in the afternoon.
"It'll be good to get them out of the way," she said before their final fling against Aorangi tomorrow.
However, they have been warned matches may be halted if the course becomes too saturated considering there'll be heavy falls from 4am to 6am before easing to showers through to 4pm.
