The 20-year-old from Alloa had already broken Gregor Tait’s record of four from a single games on Sunday but there was to be no magnificent seven as Scotland were edged out of the medal in fourth in the 4x100m medley relay.
In the individual final, Scott used his superb freestyle form to move from fourth to second in the last 50m, finishing on 1:57.86 behind gold medallist Mitch Larkin of Australia. Another Aussie, Clyde Lewis, took the bronze.
Scotland’s Mark Szaranek was fourth and Dan Wallace sixth.
In the final race of the swimming programme, Scott was left with too much to do on the final freestyle leg as Scotland finished behind Australia, England and South Africa in the medley relay.
Chad le Clos made a decisive move on the third butterfly leg to seal the bronze for South Africa as England’s Ben Proud was pipped by Kyle Chalmers to put the cherry on the cake of a dominant few days for the hosts.
Craig McNally, Szaranek and Ross Murdoch made up the Scottish quartet in the final.
Scotland’s women came fifth in the women’s relay, which saw Wales beat England to claim a surprise bronze behind Australia and Canada.
