Kiwi teen Erika Fairweather has missed out on the medals in the 400m freestyle final in Tokyo on Monday.
The 17-year-old shocked the swimming world with her formidable display on Sunday night to qualify fourth for the final.
But up against a stellar field, the Dunedin student was unable to keep pace, eventually finishing eighth with a time of 4m 08.01s.
Aussie world champion Ariarne Titmus took gold (3m 5.69s), followed by defending Olympics champion Katie Ledecky (3m 57.36s) from the US, and China's Li Bingjie (4m 01.08s).
Medal or not, Fairweather's efforts are another encouraging sign for the Kiwi swimming contingent, after Lewis Clareburt's impressive performance in the 400m individual medley.
Entering the competition ranked 15th, Fairweather's qualifying time of 4m 02.28s cut four seconds off her personal best and broke the national record previously held by Lauren Boyle.
She'll be back in action at Monday night's 200m freestyle heats, where she'll no longer be flying under any radars.
