megaphone for announcements. In 2006 the New York Mets, in honor of the 20th anniversary of the 1986 World Series, held a "turn-back-the-clock-night" and wore their 1986 uniforms. In 2009 the Mets played three games of a four-game set against the San Francisco Giants in a "fauxback" jersey based on early 20th century New York Giants' jerseys with a giant "NY" on the chest, but using the Mets' current team colors of orange and blue. (The Mets are the only team to have worn a throwback from their home city's past instead of their franchise's past; while the Minnesota Twins and Texas Rangers, both of whom were once the Washington Senators, have each used throwbacks from their previous hometown, the city's current team, the Washington Nationals, have worn both Twins-Senators and Rangers-Senators throwbacks as well.) In 2008, the Philadelphia Phillies adopted an alternate uniform based on their 1948 uniforms, but with modern graphics on an off-white color background. Not all throwbacks use Major League uniforms; at least 15 MLB teams have at some point paid tribute to the pre-integration Negro leagues by wearing the uniform of a Negro league team from the city's past; in almost every case both teams do so simultaneously. Since the Homestead Grays played "home" games in both Washington and Pittsburgh, the team has been honored as such by both the Nationals and Pirates; in 2008 the two teams did so together, with Washington wearing the Grays' home uniforms and Pittsburgh the away ones. The Tampa Bay Rays have staged a "Turn Back the Clock" promotion with a retro theme and throwback uniforms almost every season of their existence. Because the franchise does not yet have a long history from which to choose uniforms, they have often worn the uniforms of historical local teams such as the Tampa Tarpons of the Florida State League (worn in 1999, 2006, and 2010), the St. Petersburg Pelicans of the Senior Professional Baseball Association (worn in 2008), the St. Petersburg Saints (2007) and Tampa Smokers (2011) of the Florida International League, and the University of Tampa Spartans (2000). The Rays have worn their own uniforms for Turn Back the Clock night only once: in 2009, when they wore Devil Rays "rainbow" uniforms from their 1998 inaugural season. Usually, the Rays' opponent on Turn Back the Clock night wear throwbacks of their own from the same era as the Rays' retro
