Legendary Olympian Michael Phelps has returned to winning ways ahead of the 2012 Games in London.
Phelps has won a record 14 gold medals at the Olympics, including an all-time high single-Games total of eight in Beijing four years ago. However, he had suffered poor form by his standards following that tournament.
On Thursday, the American secured a fourth straight Olympic berth in the 200m butterfly at the US trials to continue his domination of the event.
"That was the best my stroke's felt throughout the meet," said the 26-year-old.
"In all I'm pleased, but I think I need to go faster if I want to win that at the Olympics.
"I was just thinking about it today, this is my fourth Olympic Games in this event, so it's special to me, special to my family, special to my mom. I have a couple of weeks to perfect some things that I'm going to need if I want to end with a good one."
Phelps has won a total of 16 Olympic medals, the second highest total in history, and has held the world record in the 200m butterfly since he was just 15 years old.
