It’s a bird... It’s a plane... It’s Caleb Serong!

The Fremantle star has taken a brilliant flying mark, challenging Superman as he got completely horizontal in the air during the club’s clash with Gold Coast.

The gun midfielder took a slips-like catch inside 50 for the Dockers, but missed the following set shot, on the eve of the first quarter at People First Stadium on Saturday.

As young teammate Matthew Johnson danced onto his right foot and put the ball into space, Serong soared to take a potential Mark of the Year contender.

The grab was even more impressive given the conditions on the Gold Coast, with heavy rainfall making the ball extremely slippery and the terrain just as tricky for the Dockers and Suns.

Despite Serong’s kick missing to the left, the Dockers took a strong 20-point lead into the first break.
