Great Britain's Luke Greenbank ended the team's competition in the pool by clinching a bronze medal in the 200m backstroke at the Youth Olympics in Nanjing.
The 16-year-old, who secured gold with the 4x100m freestyle relay team earlier this week, earned a spot on the podium after finishing the race in 2:00.83, one second off his personal best.
Greenbank's fellow Brit Duncan Smith failed to add another medal to their nation's tally after finishing sixth in the 100m freestyle final.
Charlotte Atkinson and Georgina Evans came eighth in the 200m breaststroke and 100m butterfly finals respectively.
