Brazilian swimmer Larissa Oliveira set a South American record in the 200 metres freestyle to secure a berth at this year's Olympic Games here.
The 23-year-old on Sunday clocked one minute, 57.37 seconds at the Olympic aquatic centre to eclipse the previous record of 1:58.03 set by teammate Manuella Lyrio, reports Xinhua.
The event is serving as both the final Olympic qualifying competition for Brazilian swimmers and an official test event for the newly opened venue.
