Intro:

Michael Phelps fine-tuned his butterfly during the 50-metre freestyle preliminaries at the Arena Grand Prix in Mesa, Arizona on Friday (April 25th) and failed to advance to evening's finals.

Script:

Michael Phelps' comeback was cut short on Friday when he failed to advance to the 50-metre freestyle final.

The 18-time Olympic gold medallist used the morning preliminaries at the Arena Grand Prix to fine-tune his butterfly stroke instead of doing freestyle like everyone else.

He finished seventh in a time of 24.06 seconds, missing out on the eight-man evening final.

Phelps failed to make the three consolation finals finishing 42nd overall - only the top 32 qualify for those.

His first competition since retiring after the 2012 London Olympics ends prematurely.

But the swimmer insisted that he's having fun this time around and feels more relaxed than ever.
