Triple champion Maria Astashkina became the first world record holder in the pool at the Baku 2015 European Games as she broke the junior 200m breaststroke record before helping set another global milestone in the 4x100m medley relay.
It was a night when Russia's brightest young talents shone again, Austria struck unexpected double gold and Britain's Duncan Scott took the blue riband 100m freestyle crown.
Pride of place, though, went to 16-year-old Astashkina, who clocked 2 minutes 23.06 seconds, taking six-hundredths of a second off the world junior record 'target time' set up by FINA last year.
"I wasn't expecting to beat the record, I was just trying to go faster than I did in the semi-final," said the girl from Penza.
Four-time European junior champion Astashkina destroyed the field by more than 10m, with Giulia Verona of Italy taking silver and 14-year-old Layla Black, the youngest member of the British swim team, claiming bronze.
