Who's that Marlins fan sitting behind home plate at the World Series? He's a well-traveled fan

The World Series returned to Kansas City on Tuesday night for the first time in 29 years and sitting right behind home plate, in an otherwise sea of blue, was a guy wearing a bright orange Miami Marlins jacket and a Marlins visor he sometimes turned to the side.

Lots of people watching at home had the same reaction: Who the heck is that guy and why is he wearing Marlins gear? Fair questions. Believe it or not, he's a somewhat famous traveling fan and the Marlins gear is basically his uniform.

His name is Laurence Leavy and it looks like he has a pretty sweet life. He was recently at the ALCS. He was at the World Series two years ago. He was at the NBA Finals last year. During Game 1 of the World Series on Tuesday night, so many people were talking about Leavy that it made the Marlins a trending topic on Twitter and he spawned a parody Twitter account — @WSVisorGuy.

Leavy actually has a real Twitter account. He's @Marlins_Man, and he documents many of his travels there. He always wears the same gear so people know it's him. He's posted pics with Giancarlo Stanton and Miguel Cabrera in addition to shots of himself being spotted by TV cameras.

At the 2012 World Series, Amy K. Nelson tracked down Leavy and wrote about him at SB Nation. He told Nelson he is a Marlins fan first, one of the originals, in fact, but he'll travel for big baseball games:

To prove his Marlins fandom, Leavy had a Marlins car custom made this year.

Might not be everybody's style, but you can't fault his loyalty.

Your natural inclination when you first saw the Marlins fan behind home plate during Game 1 of the World Series might have been to laugh at him. But if you're a sports fan, now that you know his story, don't you wish you were him?
