Ireland has a second gold medal at the 2020 Olympic Games after Kellie Harrington beat Beatriz Ferreira on a unanimous decision to become the champion of the lightweight division.
Harrington came into the Games as the number one seed and the final saw the 2018 world champion pitted against the 2019 world champion in a showdown for gold.
After losing the first round 3-2 on the judges cards, Harrington found her range in the second to win it on all five cards before doing the same in the final round.
It means the Dubliner follows in the footsteps of Katie Taylor who won gold in 2012 and she adds a second gold to the collection of Team Ireland after Paul ODonovan and Fintan McCarthys win in the mens lightweight double sculls rowing last week.

Emily Kay came home in 13th in the womens omnium after a bad crash derailed her efforts.
A huge pile-up crash in the opening scratch race at the Izu Velodrome threw a curveball into the race early on with at least nine riders involved.

It meant that Kay was unable to finish the opening race with all riders in the same position awarded 16 points while American Jennifer Valente won to clock up 40 points.
Kay recovered to take part in the tempo race and put in a strong performance in the points race to finish ninth, eventually a total of 56 points to finish 13th overall while Valente took gold with Japans Yumi Kajihara and Kirsten Wild of the Netherlands winning silver and bronze.

Kevin Seaward did manage to finish the race in 58th position, 13:07 behind Kipchoge while Paul Pollock finished 71st.
