Katie Ledecky is keeping fans waiting for the next heavyweight matchup between the nine-time Olympic gold medalist and Canadian star Summer McIntosh.

Ledecky, who was seeded to swim in the 200m freestyle against McIntosh at the Westmont Pro Swim Series scratched the event in favor of the longer 1500m freestyle.

Although there was no rematch between the world's best, both Ledecky and McIntosh delivered Friday night, posting some of the fastest times in the world this year in their respective events.

Ledecky was up first, dominating the pool in the 1500m freestyle, stopping the clock in 16:40.86, 41.66 seconds faster than second place. Her swim is another top ten time the world this year. Ledecky already occupies the top spot from her mark set at the Austin Pro Swim Series. Her swim on January 14th was the second fastest performance in history behind her world record set back in 2018.

Later in the session McIntosh smashed the fastest time in the world by 2.82 seconds, winning the 200m freestyle in a blazing 1:53.80. The previous mark was set in January by American Claire Weinstein, who won bronze at the World Championships last summer. McIntosh is the fifth fastest performer in history in the event with her best time being 1:53.65, set in 2023.

On Wednesday night Ledecky defeated McIntosh in the 800m freestyle, which ended up being the only time they raced head-to-head this week. They posted the first and third fastest times in the world this year in the event, posting an 8:08.57 and 8:10.45 respectively.

Ledecky’s time was the 13th fastest performance in history. She has won the last four Olympic 800m free gold medals and won her seventh straight 800m free at the World Championships last summer, becoming the first swimmer to claim seven world titles in one event.

Last night McIntosh won the 200-meter butterfly in 2:04.72. The nineteen year old went under two minutes and five seconds for the tenth time in her career, which is three more times than any other women in history. She will contest the 200m IM on Saturday, and will try to go three for three in Westmont.

The Pro Swim Series stop in Westmont finishes up Saturday, with the finals starting at 7 p.m. ET on Peacock.
