World Aquatics Championships: Adam Peaty claims third gold as GB men win medley relay
Adam Peaty claimed his third gold of the World Aquatics Championships and fourth medal overall as Great Britain won the men's 4x100m medley relay.
Peaty, James Guy, Luke Greenbank and Duncan Scott won in South Korea with a new European record of 3:28.10.
Scott swam the last leg as GB won ahead of the USA while Russia took bronze.
"That was one of greatest relay swims I have ever seen," said Britain's former world champion Karen Pickering on Radio 5 Live Sports Extra.
"Duncan Scott on that anchor leg - he could smell victory, he was chasing Nathan Adrian down. He found something so special to take that victory and deny USA another gold medal."
Caeleb Dressel swam the butterfly leg for the US but had to settle for six golds after Scott, who trailed by 0.84 seconds at the final turn, produced a split of 46.14 - the 100m freestyle world record is 47.05.
"This is incredible. I thought Jimmy could hold his ground and as soon as Duncan dived in I thought, 'We're going to get bronze,'" said Peaty.
"With 25m to go I was jumping up and down like never before and the last 10 metres he just got his head down and took him out.
"For me, that's better than Olympic gold and anything else, as when you do it as a team, and the fact the Americans have never been beaten in this event I don't think, it's just amazing."
USA topped the medal table with 13 golds in Gwangju, while GB finished seventh with three golds and seven medals overall.
As well as defending his 50m and 100m breaststroke titles, Peaty also helped GB win bronze in the mixed 4x100m medley relay.
Scott (200m freestyle) and Greenbank (200m backstroke) both won individual bronze medals, while James Wilby took 100m breaststroke silver behind Peaty.
Elsewhere on the last day of competition, GB came eighth in the women's 4x100m medley relay, which saw the USA take gold in a world record time of 3:50.30.
Anna Hopkin was seventh in the women's 50m freestyle final, with USA's Simone Manuel following up her 100m freestyle gold to win ahead of Sweden's Sarah Sjoestroem and Australia's Cate Campbell.
Fellow Briton Max Litchfield also came seventh in the men's 400m medley, which was won by Japan's Daiya Seto from USA's Jay Litherland and New Zealand's Lewis Clareburt.
