Bradley Austin Miller (born October 18, 1989) is an American former professional baseball utility player. He played in Major League Baseball (MLB) for the Seattle Mariners, Tampa Bay Rays, Milwaukee Brewers, Cleveland Indians, Philadelphia Phillies, St. Louis Cardinals, and Texas Rangers. He currently serves as a pre- and post-game analyst for the Rangers Sports Network.

Miller grew up playing Little League baseball in Windermere, Florida, before attending Olympia High School, where he served as the team's shortstop. Although the Texas Rangers selected him in the 2008 MLB draft, Miller chose to play college baseball for the Clemson Tigers. As a junior in 2011, he won the Brooks Wallace Award, given annually to the best shortstop in college baseball. Miller was also named twice to the United States national collegiate baseball team, including appearances at the 2009 World Baseball Challenge and the 2010 World University Baseball Championship.

The Mariners selected Miller in the second round of the 2011 MLB draft, and he quickly rose through the Seattle farm system, making his major league debut in 2013. Throughout the 2014 season, Miller was in competition with several other Mariners for the role of starting shortstop, and by May 2015, he was being utilized as a "super utility" player, similar to Ben Zobrist. Miller was traded to the Rays prior to the 2016 season, where he was used first as the starting shortstop, then as the starting first baseman, and finally as the starting second baseman. After a banner 2016 season in which he hit 30 home runs, a series of injuries derailed Miller's next two seasons, and he was traded to the Brewers in 2018. Miller spent only one month within the Brewers organization before he was released. He then underwent microfracture surgery to repair a torn hip labrum.

Miller spent the 2019 season with a number of teams. He opted out of a minor league contract with the Los Angeles Dodgers, and made a brief appearance with the Indians before he was designated for assignment. After Miller spent some time with the Yankees' Triple A team, the Phillies signed him to take over as their utility player after Jay Bruce became their starting left fielder. Miller spent 2020 with the Cardinals before returning to the Phillies the following year.

Miller was born on October 18, 1989, in Orlando, Florida, and grew up in Windermere. He began playing Little League baseball with a Windermere club and was childhood friends with future Major League Baseball (MLB) second baseman Nick Franklin. Miller's father, Steve, played college baseball for the Northern Iowa Panthers and served as his son's baseball coach from Little League to the beginning of high school.

Miller attended Olympia High School in Orlando, serving as the team's shortstop. As a sophomore in high school, Miller was invited to join retired MLB player Chet Lemon's summer Amateur Athletic Union team, "Juice". As a junior, Miller had a .420 batting average for Olympia, with a .560 on base percentage, six home runs, and 31 runs batted in (RBIs), and was named the team's Most Valuable Player.

The Texas Rangers selected Miller in the 39th round of the 2008 MLB draft, but he elected to attend Clemson University on a full college baseball scholarship. As a freshman at Clemson in 2009, Miller started all 66 games for the Tigers at shortstop. His first collegiate home run came on February 22, 2009, in a 6–5 extra innings victory over Charlotte. As a sophomore in 2010, Miller led Clemson with a .357 batting average. He also had eight home runs, a .458 on-base percentage, and nine stolen bases in 69 games. That same year, he helped take Clemson to the semifinal rounds of the 2010 College World Series, where they eventually fell to the University of South Carolina.

As a junior in the 2011 season, Miller led the Atlantic Coast Conference (ACC) with a .395 batting average and a .498 on-base percentage. Additionally, he recorded 11 doubles, three triples, five home runs, 50 RBIs, 53 runs, and 21 stolen bases in 56 games for Clemson, 54 of which were starts. At the end of the year, Miller received the Brooks Wallace Award, given to the best college baseball shortstop that season. Miller was also named the 2011 ACC Player of the Year and was a Louisville Slugger First-Team All-American as named by Collegiate Baseball. Clemson once again reached the college baseball postseason but was eliminated by Connecticut during the regional rounds.
