Ledecky, trailing McIntosh at the 700-meter mark, surged ahead on the final lap, fending off a hard-charging Pallister as McIntosh faded in the closing meters. With the win, Ledecky remained undefeated in the 800-meter freestyle finals event on the world stage dating back to 2012.

Australian Cameron McEvoy and Brit Ben Proud went one-two in the men's 50m free, repeating their finishes from the Olympics. American Jack Alexy added bronze to his 100m free silver. Summer McIntosh crossed an ocean and took up a new sport that helped her have one of the best swim meets in history.

Chen Yiwen and Chen Jia finish first and second in the women’s 3m springboard, while Ledecky takes seventh world title in thriller.
