4 × 100 m freestyle relay, mixed

What to remember

Two men, two women, and a free order: in the mixed relay, each team decides who swims when. At the World Championships in Singapore on August 2, 2025, the United States opened with Jack Alexy and Patrick Sammon and covered the 4 × 100 m freestyle in 3 min 18.48 s.

Jack Alexy led off in 46.91 s, Patrick Sammon followed in 46.70 s, then Kate Douglass swam 52.43 s and Torri Huske finished in 52.44 s.

The mixed relay is a recent event already on its way out: introduced at the World Championships in 2015, it was removed from the 2027 program. Jack Alexy, born in Morristown, who swam collegiately for the California Golden Bears, had represented the United States at the 2024 Paris Olympics.
