The Kiwi said having a tournament in his hometown made a difference.
“I think it’s the first time that’s happened in about 14 years playing a tournament from my own bed,” he said.
“And it’s a little more than that, my caddy’s here this week, he’s cooking. I hate to admit it, but mum’s done a few bits of laundry this week, there are no stressors. We were driving home, Tuesday afternoon after our [practice] round, just thinking I’m in my own car here, this is the route I take to practice most days, it doesn’t feel like a tournament week.
“I don’t mean that in a negative way at all, it just means it feels a bit more casual than most tournaments, quite familiar with things, fewer uncertainties, and seems to be paying dividends.”
Kazuma Kobori was the next best Kiwi in the field, in a tie for ninth at six-under.
