I was just looking at the results, and I’m not quite sure it’s true that he’s leading 5-4. He might have used the wrong format in his answer. He mentioned Sabalenka–Swiatek, but the question only asked for the winner, not both finalists. Maybe I’m wrong — we’ll see what the Mafia has to say about that.

You are right. I stand corrected.
HomieAllDay won't get any point from the tennis question. As you truly said, the question asked the winner of women's side of the US open and HomieAllDay answered that with two players.
I didn't click on HomieAllDay's answer and I just saw the Sabalenka in his answer.
