FUKUOKA, Japan, July 26 (Reuters) - Australia's Mollie O'Callaghan finished with a flourish to break the longest-standing world record in women's swimming, claiming the 200 metres freestyle title in a time of one minute, 52.85 seconds at the World Aquatics Championships on Wednesday. Summer McIntosh of Canada was 0.80 seconds behind to take bronze in a world junior record time. Olympic champion Titmus had blazed to the 400m freestyle title on Sunday to erase 16-year-old McIntosh's mark and was well placed to go for another record after topping the semi-final time sheet. Hungary's world record holder Kristof Milak was absent from the men's 200m butterfly that followed, as the Olympic and world champion skipped the meet saying that he was not physically or mentally in a position to compete. The mixed 4x100m medley relay concludes the fourth day of swimming with the Americans tipped to win their third title.
