Andrew Miller, American baseball player
Andrew Mark Miller (born May 21, 1985) is an American former professional baseball pitcher. He has played in Major League Baseball (MLB) for the Detroit Tigers, Florida Marlins, Boston Red Sox, Baltimore Orioles, New York Yankees, Cleveland Indians and St. Louis Cardinals. Primarily a starting pitcher who struggled early in his MLB career, Miller found sustained success as a reliever utilizing a multi-faceted fastball and slider approach that has proven deceptive for batters to hit. A left-handed batter and thrower, Miller stands 6 feet 7 inches (2.01 m) tall and weighs 205 pounds (93 kg).

Instrumental in the Indians' World Series run in 2016, Miller earned the American League (AL) Championship Series Most Valuable Player (ALCS MVP) honors, while setting a number of postseason strikeout records for relievers and covering multiple relief roles and innings. He is also a two-time MLB All-Star selection, and a winner of the AL Reliever of the Year Award. In 2017, he earned his first major championship in the World Baseball Classic as a member of the United States national team. His collegiate baseball awards include the Baseball America College Player of the Year and Roger Clemens Awards.

A native of Gainesville, Florida, Miller attended the University of North Carolina (UNC) at Chapel Hill, playing for the UNC Tar Heels. The Detroit Tigers selected him sixth overall in the 2006 MLB draft, and he made his MLB debut that same season after three minor league appearances. After commencing his career in MLB with a 5.70 earned run average (ERA) over 66 starts with Detroit and Florida, he converted to full-time relief in 2012 with Boston, and has since served in middle relief, setup and closer roles. The Red Sox traded Miller to the Orioles in 2014, and Miller signed as a free agent with the Yankees after the season. The Yankees traded Miller to the Indians during the 2016 season, and in 2019 he signed with the Cardinals. He pitched in seven playoffs, including with Baltimore, New York, Cleveland and St. Louis.
