US gymnastics star Simone Biles clinches a record-extending 15th world championship title as US wins world gymnastics team Gold in Stuttgart, Germany; with this win, Simone Biles becomes the event’s most decorated woman.

US gymnastics star Simone Biles won a record 21st medal at the world gymnastics championships yesterday as the United States retained their women’s team all-around title.

Biles’ 15th career gold medal brings her a total of 21 medals, breaking a tie with the Russian gymnast Svetlana Khorkina for the most medals by a woman at the world championships.

The US women claimed gold with a tally of 172.330, well ahead of the Russians who took silver with 166.529, while bronze went to Italy on 164.796.

Biles played a key role in a commanding performance by the USA, earning the most points in three of the four disciplines — the vault, balance beam and floor.

She is expected to add more medals to her dazzling tally as the favourite in the women’s all-around final and this weekend’s apparatus finals.
