World record for the Australian 4 x 100 relay team plus a world record and Hungary's Katinka Hosszu in the 400m individual medley
Australia turned to the best sister act in swimming to hold off an American team anchored by Katie Ledecky. Give the gold to Cate and Bronte Campbell. And a world record, too.
The Campbells carried their squad to victory in the 4x100-metre freestyle relay Saturday night at Rio 2016, with little sister Bronte snatching the lead from Dana Vollmer on the third leg and big sister Cate pulling away from Ledecky on the final down-and-back for a time of 3 minutes, 30.65 seconds.
The Aussies broke their own mark of three minutes 30.98 seconds set two years ago.
That wasn't the only world record to fall on a late night of swimming to kick off the Olympic Games. Shaking off repeated frustration on the sport's biggest stage, Katinka Hosszu of Hungary crushed the world record in the women's 400 individual medley to make the first Olympic medal of her career gold.
