Laurence Leavy (born October 13, 1956), better known as Marlins Man, is an American sports fan and lawyer from North Miami Beach, Florida.

Leavy wore an orange Marlins jersey and visor among the sea of white promo T-shirts, increasing his visibility on television.

Later that year, Leavy was seen sitting behind home plate at AT&T Park during the World Series between the San Francisco Giants and the Detroit Tigers[3] wearing a brightly-colored jersey of neither team that was playing, increasing his visibility on television again.

According to Leavy, he began attending Miami Marlins games as a full season ticket holder in 1993, the year the team started.

[10] In March 2018 he told ESPN that he planned to discontinue his 25-year history of purchasing season tickets due to disagreements with the club over pricing.

[10] Despite this turn of events, on September 17, 2018, Leavy won a charity auction to be a player for a day, which resulted in him signing a one-day "contract" with the Marlins.
