(BSS/AFP) - Former world number one Naomi Osaka reached her first semi-final since 2022 after fighting back at the Auckland Classic

on Friday.

The four-time Grand Slam champion beat unseeded American Hailey Baptiste 6-7 (2/7), 6-1, 6-2 in another confidence boost ahead of the Australian Open in Melbourne.

Osaka said her hard work was starting to pay off after booking a place in the
final four of a WTA event for the first time since the Miami Open in April
2022.

The Japan star gave birth to daughter Shai in July the following year, midway
through a 15-month break, before returning to the tour 12 months ago.

"I put a lot of work in throughout last year and even though the results
didn`t show it, I`m just continuing to try as hard as I can to see where it
gets me," the 57th-ranked Osaka said.

"The key focus again today was just to have a lot of belief and confidence in
myself."

As with her first two matches in Auckland, the 27-year-old lacked rhythm in
the opening set.

She unearthed a powerful serving game over the next two sets, ending with
nine aces to give her 21 for the tournament.

World number 92 Baptiste sought treatment for an ankle injury during the
second set.

Osaka, a two-time Australian Open champion, admitted that helped her cause.

"She`s an amazing player, it sucks that she was injured but I think we played
a really high-quality match," said Osaka, who is seeded seventh in Auckland.

"In a weird way I`m glad to play a three-set match because I think that`s the
kind of experience that I need."

Osaka`s semi-final opponent will come from the winner of a quarter-final
later on Friday between eighth seed Katie Volynets and unseeded American
compatriot Alycia Parks.
