MERCURY METS NEW YORK New Era Hat Cap Fitted 7 3/8 Turn Ahead The Clock Major League Baseball sold the promotion concept to Century 21 Real Estate. The New York Yankees, Chicago Cubs, Toronto Blue Jays, Texas Rangers, Montreal Expos, Houston Astros, Cincinnati Reds, and Los Angeles Dodgers did not participate in the promotion. The teams that did participate wore special sleeveless jerseys with oversized front logos and players' surnames being printed on the side of the number, instead of its traditional place above the number. (This style was also used for the that year's All-Star Game batting practice uniforms.) Uniform changes ranged from the subtle (the St. Louis Cardinals changing the "birds on the bat" from living beings to robotic depictions) to the outlandish: the New York Mets changed their names to the "Mercury Mets" (complete with caps featuring the ☿ symbol) while hosting the Pittsburgh Pirates on July 27, 1999. In games, which were "set" in the year 2021, stadiums would use futuristic graphics on their scoreboards as a part of the promotion. During a Padres / Giants game, fielding positions were renamed. Shortstop was renamed "intermediate station" and left field was renamed "left sector". Some ballpark advertisements also joined in, with Northwest Airlines becoming "Northwest Spacelines" (this can be seen when Mariners outfielder Butch Huskey crashed into the outfield wall during a game). The Mets proved most ambitious.
