John Claiborn Mayberry, Jr. is an American professional baseball outfielder for the Toronto Blue Jays of Major League Baseball. He attended high school in Kansas City, and played both baseball and basketball. Ultimately, baseball was his first love, and in the 2002 Major League Baseball Draft, the Seattle Mariners drafted him out of high school. However, he chose not to sign, instead attending Stanford, where he played three years before being drafted again. He also played for the United States national baseball team at the World University Baseball Championship in 2004. The Texas Rangers selected him in the 2005 Major League Baseball Draft. Mayberry ascended through the Rangers' minor league system, ultimately reaching Triple-A level, by which point he was considered a legitimate major league prospect. In 2007, he began to amass strong power numbers in the minor leagues, and on November 20, 2008, the Philadelphia Phillies acquired him. With the Phillies, he started in Triple-A, but was called up to the major league team in May. He hit a home run in his major league debut, but was sent back to the minors a few weeks later, and spent the majority of the 2009 and 2010 seasons there.
