The New York Mets are an American professional baseball team based in New York City, They play in Flushing, in the borough of Queens. The Mets are a member of the National League East Division of Major League Baseball (MLB). The Mets are one of two Major League clubs based in New York, the other being the New York Yankees. One of baseball's first expansion teams, the Mets were founded in 1962 to replace New York's departed National League teams; the Brooklyn Dodgers and the New York Giants. The Mets' colors are composed of the Dodgers' blue and the Giants' orange, which also comprises the outer two bands of the New York City flag. During the 1962 and 1963 seasons, the Mets played their home games at the Polo Grounds. From 1964 to 2008, the Mets' home ballpark was Shea Stadium. In 2009, they moved into their current ballpark, Citi Field. In their 1962 inaugural season, the Mets posted a record of 40–120, the worst regular season record since Major League Baseball went to a 162-game schedule (two games were canceled). The team never finished better than second to last until the 1969 "Miracle Mets" beat the Baltimore Orioles in the 1969 World Series in what is considered one of the biggest upsets in World Series history. Since then, they have played in four additional World Series, including a dramatic run in 1973 that ended in a seven-game loss to the Oakland Athletics, a second championship in 1986 over the Boston Red Sox, a Subway Series loss against their cross-town rivals the New York Yankees in 2000, and a five-game loss to the Kansas City Royals in 2015. The Mets made the playoffs in 2006 when they came within one game of the World Series, losing to the eventual champion St. Louis Cardinals in the NLCS. The Mets missed the playoffs with losses on the last day of the regular season in 2007 and 2008. The Mets made the playoffs in 2015 for the first time in nine years, and won their first National League pennant in 15 years.

The Seattle Mariners are an American professional baseball team based in Seattle. The Mariners compete in Major League Baseball (MLB) as a member club of the American League (AL) West Division. The team joined the American League as an expansion team in 1977, playing their home games in the Kingdome. Since July 1999, the Mariners' home ballpark has been T-Mobile Park, located in the SoDo neighborhood of Seattle. The "Mariners" name originates from the prominence of marine culture in the city of Seattle. They are nicknamed the M's, a title featured in their primary logo from 1987 to 1992. They adopted their current team colors – navy blue, northwest green (teal), and silver – prior to the 1993 season, after having been royal blue and gold since the team's inception; the original colors continue to be used in alternate uniforms. Their mascot is the Mariner Moose. The Mariners did not field a winning team until 1991, and further success eluded them until the late 90s, the most successful period in franchise history. Led by Hall of Fame players Edgar Martínez, Ken Griffey Jr., and Randy Johnson, the Mariners clinched their first playoff berth in 1995 when they won their first division championship and defeated the New York Yankees in the ALDS. Martínez's walk-off double in Game 5 drove Griffey in from first base to win the game in the 11th inning, clinched a series win for the Mariners, served as a powerful impetus to preserve baseball in Seattle, and has since become an iconic moment in team history. They would later win their second division title in 1997. After Griffey, Johnson, and Alex Rodriguez all left the team, the Mariners, bolstered by the signing of Ichiro Suzuki, won 116 games in 2001, which set the American League record for most wins in a single season and tied the 1906 Chicago Cubs for the Major League record for most wins in a single season. The team would not make the postseason again until 2022, which was the longest active drought in the four major North American sports. As of 2024, the franchise has finished with a losing record in 30 of 48 seasons. The Mariners are the only active MLB franchise never to have appeared in the World Series, currently holding the longest active World Series appearance drought in MLB.
