Michael Phelps booked himself into another event at the London Olympics when he won the 200 metres butterfly final at the U.S. swimming trials.
The greatest Olympian of all time remained on course to emulate his incredible eight-gold haul from Beijing four years ago with another powerful display in America's midwest.
Showing no sign of fatigue or weariness despite his gruelling schedule, the 26-year-old powered away from his rivals over the final two laps to win in one minute 53.65 seconds, more
than two seconds outside his world record but still the fastest time in the world this year.
"It's not a good enough time to win a gold medal, but I think I'm okay with it," said Phelps.
