Leavy's presence was first noted while attending a 2012 NBA Playoffs basketball game featuring the Miami Heat, where the team distributed white T-shirts before the game. Leavy had attended a Marlins game earlier the same day, and the white T-shirt he was given at the door was stolen from his seat, causing him to be visible on television in his now trademark orange Marlins jersey and visor. Later that year, Leavy was seen sitting behind home plate at AT&amp;T Park during the World Series between the San Francisco Giants and the Detroit Tigers. The following day, a park ranger near the Golden Gate Bridge coined the term "Marlins Man".
