Maddi Levi is just ridiculous.

The winner will meet Canada in the semis.

Super impressive all around performance from Mollie O'Callaghan, who publicly acknowledges her struggles with performance anxiety.

They were healthy nerves today as she wins gold ahead of one of the all-time great freestyle swimmers.

"You've got to accept the challenge at the end of the day," O'Callaghan tells Nine.

"You can either run or... fight. I chose to fight. I'm always striving for more and I always put a lot of pressure on myself. My expectations are very high. That was an amazing race. I'm always wanting that little bit more.

"I just had to go with (coach) Dean (Boxall) and trust him knowing what to do and what's best. To be honest, I did it for the country, I didn't do it for myself. I'm racing for all these people. I just had to put it behind me. Less pressure now, I get to swim freely."
