DOHA — Katinka Hosszu set her fourth world record at the Short-course World Championships when the Hungarian swimmer smashed her own mark to win the women's 200m individual medley Saturday. Hosszu crushed the field and touched in 2 minutes, 01.86 seconds, bettering her record of 2:02.13 set in August in Dubai. Her fourth record and gold medal of the meet equaled Mireia Belmonte Garcia's tally, with the Spaniard not in action in any of the finals on Saturday at Hamad Aquatic Centre. “I wanted to break another two-minute barrier. But I am happy with the record,” Hosszu said. On the penultimate day, Alia Atkinson equaled a world record, and three more marks were broken. Atkinson became Jamaica's first short-course world champion when she won the women's 100 breaststroke final, not only holding off defending champion Ruta Meilutyte, but also matching her mark of 1:02.36. Lithuania's Meilutyte finished second. Meanwhile, Florent Manaudou of France set his second record in 24 hours, in winning the men's 50 backstroke. Manaudou set a record in the 50 freestyle final on Friday. On Saturday, he timed 22.22 seconds, erasing 0.39 seconds off the previous mark set in a suit in 2009 by Peter Marshall of the U.S. South Africa star Chad Le Clas earned his third gold in the 50 butterfly, and Russia improve its own record mark in taking the men's 4x50 freestyle relay. Vladimir Morozov, Evgeny Sedov, Oleg Tikhobaev and Sergei Fesikov finished in 1:22.60 seconds, slicing 0.76 seconds off their previous record. The US took silver in 1:23.47, and Italy bronze in 1:24.56. In the mixed 4x50 freestyle relay, the United States team of Josh Schneider, Matt Grevers, Madison Kennedy and Abbey Weitzeil won in 1:28.57 to better Russia's 1:29.53 set last year. Russia took silver in 1:29.13, and Brazil bronze in 1:29.17. Swimming will be late in Rio Swimmers and beach volleyball players will be competing in the midnight hour at the 2016 Olympics in Rio de Janeiro. The International Olympic Committee and Brazilian organizers confirmed Friday that the competition schedule includes late-night sessions in the two sports — swimming finals running from 10 p.m. local time to midnight, and some beach volleyball matches starting at midnight on Copacabana Beach.
