Already considered the finest gymnasts of this generation, and possibly ever — with Biles now holding a record number of world golds for a woman — the two all-around champions once again showed their ability to produce 24-karat-winning routines. American Biles maintained her poise during a mesmerizing balance beam display to obliterate the opposition with a score of 15.358, more than a point ahead of Dutchwoman Sanne Wevers. While wobbles and falls littered the programs of the seven other finalists, with four gymnasts slipping off the beam, Biles was rock solid as she spun around 900 degrees on her right toes. An hour later she was back to dazzle again with a hip-swinging floor-exercise. After a score of 15.800 earned her a fourth title in Scotland, the 18-year-old might consider employing the services of a bodyguard as she heads back to her Texan home with a heavy load of precious metal. While Biles will arrive at the Rio Olympics a three-time all-around world champion, Japan's Uchimura showed that his appetite for gold remains insatiable. The holder of a record six successive world all-around titles ended the theatrical celebrations of American Danell Leyva, and his step-father-coach Yin Alvarez, with a high-flying routine on the horizontal bar that drew 15.833. A performance that had the crowd oohing and aahhing with every one of his four release maneuvers secured him a third gold in Glasgow, taking his overall worlds medal tally to 19. While Biles and Uchimura were the leading lights Sunday, Ri Se-gwang was saluting North Korea's flag as his country's national anthem was played for the second year running following his success in the vault final. The 30-year-old took a step forward following his first vault and then stuck his tongue out bashfully when he failed to nail the second one cleanly. But there was so much difficulty packed into his Tsukahara full-twisting double back effort, that the stumbled landing did not really dent his average score. His mark of 15.450 edged out Marian Dragulescu by 0.050 of a point. You Hao ended a week of disappointment for China's men as he captured their first gold medal in Glasgow by eclipsing Ukrainian defending champion Oleg Verniaiev by 0.15 of a point in the parallel bars final. He scored 16.216 on a day Asia won all three of the men's apparatus finals.
