Question: How many American League championships have been won by the baseball team that has played in New York since 1903? Passage:In New York, baseball is still regarded as the most popular sport, despite being overtaken by football in terms of perceived popularity (but not attendance) throughout the country, as based on TV ratings and consistent fan following for the entire season. New York is home to two Major League Baseball franchises. The New York Yankees of the American League have played in New York since 1903. Known for iconic ballplayers such as Babe Ruth, Lou Gehrig, Joe DiMaggio, Mickey Mantle, Yogi Berra and countless others, they play in Yankee Stadium in the Bronx and have won the World Series twenty-seven times. The New York Mets have represented New York in the National League since 1962. The Mets play in Citi Field in Flushing, Queens and have won five NL pennants and two World Series, thus making them one of the most decorated expansion teams in Major League Baseball. The "Subway Series" is the name used for all regular season and World Series meetings between the two teams. Before interleague play was introduced in 1997, the only instance these two teams could have played each other would have been in the World Series. The Mets and Yankees played for the World Series in 2000, with the Yankees winning the series 4–1.
