Le Clos added to his three-medal haul on the opening day of the Beijing leg, the last in the lucrative annual series, as he secured the overall World Cup crown for the second time in his career.
He managed to outstretch American Thomas Shields to win the 100m butterfly final by 0.04sec, touching the wall in 49.41, and won the 200m individual medley in 1:52.60, nearly a full second clear of China’s Wang Shun.
Veteran Roland Schoeman, meanwhile, snatched his third medal of the Beijing leg, securing bronze in the 50m freestyle in 21.11, with Russian Vladimir Morozov taking gold in 20.91.
Myles Brown, who bagged a silver medal on Wednesday, went one better in yesterday’s 1 500m freestyle final.
Brown trailed Hao Yun of China for most of the race but moved ahead with 300m to go to win in 14:41.63.
Le Clos scooped an astounding 35 medals over the eight legs, pocketing 24 gold, eight silver and three bronze to regain the series title he won in 2011.
He also improved the 200m butterfly short course world record twice, lowering Brazilian Kaio Almeida’s four-year-old mark by more than half a second, bringing it down to 1:48.56 at the sixth leg in Singapore.
