“I’m in a really different frame of mind,” she said ahead of her opening match on day one — a marquee doubles appearance partnering Caroline Wozniacki — with her first-round singles against long-time rival Svetlana Kuznetsova expected on Tuesday.
Williams was way below par when she played in Auckland in 2017, complaining about the windy conditions, being abrupt in interviews and could not wait to get out of the country as soon as she lost in the second round to Madison Brengle.
But she says the anger she felt then has gone.
“I’m not pregnant, as a start, so that works, so I can only do good now,” the tournament top seed and world number 10 joked with journalists as she reflected on how she was unaware at the time that she was six weeks pregnant with her daughter Alexis Olympia.
“Obviously at the time I didn’t know why either … I was six weeks pregnant and I had no idea. So looking back it’s so surreal and crazy and now that I’m here, I have all of these funny memories of being miserable.
“I always knew that I would have to come back, for sure. I didn’t even realize what was happening, and now I’m here with my daughter.
Despite her quick exit in 2017, Williams went on to win the Australian Open for her 23rd major title, but has not won a tournament since.
Williams, who has a 10-3 record against Kuznetsova in a 16-year rivalry, said she was pleased to be playing her “really good friend” first up.
“I like to play really tough opponents in the first round, and there’s no better way to start than to start serious. I really love her and adore her, and I wish it could’ve been a little bit later, for both of us,” she said.
Andreescu defeated Williams to claim the US Open title in September last year.
