The Arizona Diamondbacks (often shortened as the D-Backs) are an American professional baseball team based in Phoenix, Arizona. They play in the West Division of Major League Baseball's National League. Since the team's inception in 1998, the franchise has played home games at Chase Field, formerly known as Bank One Ballpark. The ballpark was renamed in 2005 as a result of Bank One Corporation's merger with JPMorgan Chase & Co. The Diamondbacks have won one World Series championship (in 2001), becoming the fastest expansion team in the major leagues to win a championship, doing it in only the fourth season since the franchise's inception in the 1998 Major League Baseball season.

The Texas Rangers are an American professional baseball team located in the Dallas–Fort Worth metroplex and based in Arlington, Texas. The Rangers franchise is currently a member of the West division of the American League (AL) in Major League Baseball (MLB). Since 1994, the Rangers have played in Globe Life Park in Arlington in Arlington, Texas. The team's name is borrowed from the famous law enforcement agency of the same name. The franchise was established in 1961 as the Washington Senators, an expansion team awarded to Washington, D.C., after the city's first American League ballclub, the original Washington Senators, moved to Minnesota and became the Twins. After the 1971 season, the new Senators moved to Arlington, Texas, and debuted as the Rangers the following spring. The Texas Rangers Baseball Club has made seven appearances in the MLB postseason, six following division championships in 1996, 1998, 1999, 2010, 2011, and 2015 and as a Wild Card team in 2012. In 2010, the Rangers advanced past the Division Series for the first time, defeating the Tampa Bay Rays. Texas then brought home their first American League pennant after beating the New York Yankees in six games. In the 2010 World Series, the franchise's first, the Rangers fell to the San Francisco Giants in five games. They repeated as American League champions the following year, then lost the 2011 World Series to the St. Louis Cardinals in seven games.
