Olympic great Michael Phelps swam a third 2015 world-best time in as many days in the 200m individual medley at the USA National Championships. The 30-year-old, excluded from the World Championships by USA Swimming after a drink-drive conviction, won in one minute 54.75 seconds in Texas. Phelps, an 18-time Olympic champion, also recorded the year’s fastest times to win the 100m and 200m butterfly.
