Duncan Scott in fourth and he's in the final! Brazilian Chierighini also qualifies and the crowd has gone absolutely wild.

Katie Ledecky goes in lane 5 in what is comfortably her weakest race. WR holder Pellegrini in lane 3 and Sarah Sjostrom in lane 4.

Katie Ledecky edging ahead now down the penultimate straight and she's bang on world record pace at the final turn.

Katie Ledecky wins! What a race from the American who absolutely flew down the final 100m. Sjostrom gets the silver and Emma McKeon the bronze.
