More gold for Dressel, Ledecky and McKeown

Caeleb Dressel and Katie Ledecky added to the United States' gold medal haul at the Tokyo Games on Saturday while Australia picked up an incredible seventh title and Britain won the Olympics' inaugural mixed 4x100 medley relay for their fourth swimming gold.

It has been a disappointing Games so far for the U.S. swim team, whose eight golds are just half their tally from Rio, but the performances of their biggest names gave them reason to celebrate on the penultimate day in the pool.

Dressel stormed to the 100m butterfly title with a world record time of 49.45 to pick up his second individual gold of the Games. He also won gold in the 4x100 freestyle relay.

World champion Dressel beat Hungary's Kristof Milak, the gold medallist in the 200m fly, by 0.23 seconds.

The powerful American, who also won gold in the 100m freestyle, was fastest out of the blocks and never looked in danger, though Milak came back hard to close the gap down the straight.

"It took a world record to win the Olympic final. And I don't think it happens that often in the Olympics," said Dressel, who paid tribute to his rival.

After losing her 200 and 400 titles to Australia's Ariarne Titmus, Ledecky got her Tokyo campaign back on track by winning the 1,500 earlier in the week and on Saturday became the first female swimmer to win six individual golds, cruising home in the 800.

Taking control from the start, Ledecky increased her lead over Titmus from the 500 mark and came home more than a second ahead of her Australian rival, winning the event for a third straight Games -- another first for the American.

While Titmus had to settle for silver there was plenty for Australia to celebrate with Kayleen McKeown s perfectly timed swim to complete the backstroke double.

McKeown turned up the pace on the final lap of the 200m to power past Kylie Masse after the Canadian held the lead for the first 150.

The Australian won in a time of 2:04.68 with Masse 0.74 behind and McKeown's team mate Emily Seebohm taking the bronze medal.

McKeown asked to receive her gold medal from Seebohm, who has now medaled in four straight Games, and shared the top of the podium with her.

"I had a bit of a tear in my eye to be honest," McKeown said.

Australia's women have now picked up six of the country's seven gold medals in the pool.

The first mixed 4x100m medley race at the Olympics delivered all the unpredictable excitement that was hoped for when it was introduced to the programme with Britain winning with a world record time of 3:37.58.

Meanwhile, Australian Emma McKeon could bow out of Tokyo 2020 on Sunday as the first female swimmer to win seven medals at a single Olympics.
