Tokyo 2020: Jacobs and Tamberi double Italy's gold tally as USA leapfrog Japan

Tokyo, August 2: A decorated final day in the pool and Xander Schauffele's golfing gold saw the United States leapfrog hosts Japan and go second in the Tokyo 2020 Olympics medal table behind China.

Caeleb Dressel took his gold haul to five with victory thanks to victory in the 50 metres freestyle before swimming the butterfly leg as the USA broke the world record in the men's 4x100m medley.

Australia's Emma McKeon became the first female swimmer to win seven medals at a single Olympics, doubling her gold tally to four by matching Dressel's 50m and medley exploits.

In open water, there was further Australian success as Matt Wearn won the men's one-person laser event, while Logan Martin's victory in the inaugural BMX freestyle means his country are up to fourth in the medal table.

That's a place above the Russian Olympic Committee, who were guaranteed gold as Anastasia Pavlyuchenkova and Andrey Rublev overcame team-mates Elena Vesnina and Aslan Karatsev in the tennis mixed doubles gold medal match.

The big story of Sunday came late on at the Olympic Stadium as Marcell Jacobs stunned the competition to win the men's 100M in a European record time of 9:80, a few moments after fellow Italian Gianmarco Tamberi earned a share of gold in the men's high jump.

Gymnast Max Whitlock retained his pommel horse title and Charlotte Worthington triumphed in the women's BMX freestyle final thanks to a ground-breaking 360-degree backflip, taking Team GB to 10 golds in total.

China's Sunday successes came courtesy of Gong Lijiao in the women's shot put, Chen Yufei in the women's badminton singles and now four-time Olympic champion Shi Tingmao in the women's three-metre springboard diving.
