Australian swimmer Cameron McEvoy improves the 17-year-old world record in the 50 m crawl.
At a meeting in Shenzhen, China, the 31-year-old Olympic champion clocked 20.88 seconds. He was three hundredths faster than the Brazilian Cesar Cielho, who swam his time in 2009 in polyurethane suits, which are now no longer permitted.
