Michael Phelps clocks fastest 200m butterfly in 2015

Michael Phelps has clocked the fastest 200m butterfly time in the world this year at the USA National Championships.

The most decorated Olympian of all time won in 01:52.94 in San Antonio, Texas.

"Anything is possible if you do want something bad enough," Phelps told reporters. "It's good to do it on my own shore in the country that I represent.

"I went through a lot, and to be able to train like I did to get ready for this and do that, I can do whatever I put my mind to."

Phelps, 30, served a six-month ban and was excluded from the World Championships by USA Swimming after a drink-drive conviction in December.
