Stuttgart, Oct. 14 (AFP): US gymnastics star Simone Biles won her fifth gold medal in the women's floor final Sunday to conclude her "best ever" world championships and take her career record to 25 medals.
Biles, who won the beam title earlier in the day, also claimed an unrivalled 19th world gold following her previous successes in the team, all-around and vault events in Stuttgart.
"This is really the best worlds performance I have ever put out," she said after finishing her fifth world championships with five titles in six events.
Biles was crowned world floor champion for the fifth time after winning by a full point from team-mate Sunisa Lee, who earned silver with Russia's Angelina Melnikova taking bronze.
"I just couldn't move at the end, I was so tired," Biles confessed after her sixth and final event in Stuttgart.
Her double gold success Sunday came within a two-hour spell after earlier winning the beam final with Liu Tingting, 19, taking silver and 16-year-old Li Shijia claiming bronze.
"It meant a lot," said Biles of her gold on the beam. She had to settle for bronze in the event at the 2016 Olympics and last year's world championships in Doha.
"I'm thrilled with that performance, it was probably the highlight" of the week.
