Cate Campbell's comeback to the pool has gathered even more steam, with the sprint star rattling off the fastest women's relay split in history to anchor the gold-medal winning mixed medley team at the Pan Pacs in Tokyo.
It was an astonishing performance from the Queenslander, who hit the water with a clear lead over Japan's Tomoi Aoki and Olympic and world champion Simone Manuel, who could only steer her US squad to a surprise bronze.
Campbell was electric. No female has gone sub-51s on a relay leg and she streeted clear to give the Dolphins their first gold of the night and nudge the world record mark, with their 3min 38.91s just missing the 3:38.56 set by the Americans at last year's World Championships.
"The coaches have been scheming to put together the fastest team. They got it right this time," Campbell said.
"I knew that it was going to be tight, whether it was Japan or the US or even Canada. For me it was just about keeping a cool head and swimming my race. I got us home, which I'm pretty pleased about. Nobody likes to get caught."
