The Italian international made the podium in the 100m and 200m butterfly individual events and also the men’s 4x100m freestyle relay.
In the 100m butterfly he clocked a time of 52.42 seconds to touch third behind Russian Andrei Minakov and Hungarian Kristof Milak.
He then won his relay medal in Argentina before ending the competition on Friday with his third bronze in the 200m butterfly. The 17-year-old clocked 1:57.16 to finish behind winner Milak and Ukraine’s Denys Kesil, who took second, in a high-class race. Milak, 18, and Burdisso had also finished first and third at the European Senior Championships in Glasgow in August with even faster times.
Meanwhile, Plymouth Leander had three swimmers competing in Buenos Aires – Liam Davis representing Zimbabwe, Victoria Russell competing for Bahamas and Madelyn Moore from Bermuda.
Davis swam 2:21.59 to finish second in his heat of the 200m breaststroke. That ranked him 20th overall.
Russell clocked 28.40 seconds in the women’s 50m butterfly to finish 27th overall.
Moore swam 58.81 seconds for the 100m freestyle, 28.96 for the 50m butterfly, 30.59 for the 50m backstroke and 26.81 for the 50m freestyle.
