Mitchell William Maier (born June 30, 1982 in Petoskey, Michigan) is a Major League Baseball outfielder for the Kansas City Royals.
Maier attended the University of Toledo. In the 2003 Major League Baseball Draft, he was a first round selection. He was selected 30th overall by the Kansas City Royals.
Maier began his professional career in 2003 with the AZL Royals as a catcher. He played in 51 games, batted .350 and hit two home runs. In 2004, Maier was converted over to third base. He played for two Single-A teams in 2004, the Burlington Bees and the Wilmington Blue Rocks. In 2005, Maier was converted to another position again, this time to the outfield, due to the presence of third base prospect Mark Teahen in the organization. He played for the Single-A High Desert Mavericks in 2005 and also played for the Double-A Wichita Wranglers.
