Warsash star Laura Chase (Portsmouth Northsea), who won Junior Olympics bronze in Murcia, Spain, last month in the 800m freestyle, swam only a fraction slower in Sheffield to win the 14 years' 800m.
That was just the start of a rich vein of form for the pupil at Brookfield School in Sarisbury Green.
She won the 200m medley in 2min 24.99sec, finishing nearly two seconds clear; and clinched a harder-fought 200m butterfly in 2:24.20.
On Thursday, Chase added the 400m medley crown, outstripping the field by over five seconds in 5:02.81.
Chase was second in the 400m free and dead-heated for fourth in the 100m free - but bounced back to win a tight 200m backstroke in 2:23.05.
