Naomi Osaka insisted she was unaffected by the saga surrounding Novak Djokovic ahead of the Australian Open.
Osaka opened her title defence at Melbourne Park with a 6-3 6-3 win over Colombian Camila Osorio on Monday.
The lead up to the year's first grand slam was overshadowed by the visa saga around Djokovic, who was deported from Australia on Sunday.
But Osaka, a four-time major winner, said the Serbian world number one's situation had no impact on her.
"I mean, to be completely honest, it didn't really affect me. I saw that it affected the men's draw a little bit so you might have to ask a men's player," she said.
"For me, my goal even before this whole situation is to just focus on myself more, what I need to do to become better.
"I wasn't really, I guess, looking at the news too often."
Osaka was unwilling to be drawn on whether Djokovic, whose visa was cancelled by immigration minister Alex Hawke, should be competing in the tournament.
A two-time champion in Melbourne, Osaka said her focus was on herself – with a second-round clash against Madison Brengle awaiting her.
"I feel like people focus on whatever they want to focus on. It's more like an individual question," Osaka said.
"Me, I'm a tennis player. I'll focus on my matches. You, as I guess an audience, focus on whatever is in the news, no?"
