Here’s what’s happened overnight...
Dean and Scott deliver GB one-two
24 hours after Adam Peaty won Team GB’s first gold medal of these Games there was more glory in the pool as Tom Dean produced a stunning swim to win the men’s 200m freestyle final.
With team-mate Duncan Scott taking the silver, the 21-year-old led home the first British one-two in the pool since the 1908 Olympics.
Osaka stunned in tennis singles
Home favourite Naomi Osaka suffered a shock exit in the last 16 of the women’s singles as she was beaten in straight sets by the Czech Republic’s Marketa Vondrousova.
Osaka had been considered the face of the Games and lit the Olympic flame at last week’s opening ceremony but joins world No1 Ash Barty in bowing out early.
Taylor-Brown fights back for silver
As Typhoon Nepartak hit Japan, the women’s triathlon took place in wet and windy conditions on Tokyo Bay as Bermuda’s Flora Duffy won her country’s first-ever Olympic title.
The day after Alex Yee had won silver for Team GB in the men’s event, Georgia Taylor-Brown did likewise in the women’s, defying a bike puncture with a brilliant performance in the 10km run.
Jacoby beats King in huge upset
Lydia Jacoby became the first Alaskan to win an Olympic title as she stunned defending champion and world record-holder Lilly King in the women’s 100m breaststroke final.
King had not lost in the event since 2015 but had no answer to her 17-year-old American team-mate, taking bronze as South Africa’s Tatjana Schoenmaker grabbed the silver.
