What happened?
O'Callaghan created history yet again, taking down the short-course 200 free world record for the second consecutive time.
She cruised through with ease, earning her a $10,000 bonus and adding another $10,000 to her bonus for breaking her own world record.
Why it matters for Mollie O'Callaghan
The five-time Olympic gold medalist became the first swimmer to break the 1:50 sub, upgrading her previous record of 1:49.77 set last weekend in Westmont.
O'Callaghan's win helped her wrap the event with a historic sweep.
What comes next?
O'Callaghan will look forward to completing the meet, aiming for a podium finish in the 100-meter free.
She can provide a strong competition to Kate Douglass, who is in line to claim the triple crown in the event this weekend.
The Australian swimmers have dominated multiple events at the last stop of the World Cup.
McKeown successfully clinched the triple crown in the 50 backstroke in 25.35, a new world cup and oceanian record.
Lani Pallister also claimed a new 400 freestyle world cup and oceanian record in 3:51.87, becoming the third swimmer to break the 3:52 sub.
O'Callaghan stayed ahead of the field, with a lead of three-quarters of a second after racing the opening 50 meters in 25.45.
She maintained the world record pace throughout, only slowing down in the last 50-meter lap.
O'Callaghan was followed by her teammate, Lani Pallister, matching her personal best time in 1:51.75.
New Zealand's Erika Fairweather placed third in 1:52.71.
"If you set your mind to it, you can achieve it, and if you put the hard work in it and have a great support team behind you, anything's possible," O'Callaghan said, crediting her performance to her Olympic coach Dean Boxall and the rest of her support team.
O'Callaghan is now the fastest swimmer in the short-course 200 freestyle, surpassing Siobhan Haughey (1:50.31) and freestyle legend Sarah Sjostrom (1:50.43).
