Prince Semien Fielder (born May 9, 1984) is an American former professional baseball first baseman and designated hitter, who played in Major League Baseball (MLB) for the Milwaukee Brewers, Detroit Tigers, and Texas Rangers. He was selected in the first round of the 2002 Major League Baseball draft by the Brewers out of Eau Gallie High School in Melbourne, Florida, and spent the first seven years of his MLB career with the Brewers before signing with the Tigers, in January 2012. In November 2013, Fielder was traded to the Rangers, where he played the remainder of his career.
Fielder is a six-time All-Star. He holds the Brewers' team record for home runs (HR) and runs batted in (RBI) in a season and is the youngest player in National League (NL) history to hit 50 home runs in a season.   He became the first Brewer to win the Home Run Derby, defeating Nelson Cruz in the final round of the 2009 derby. Fielder also won the 2012 derby, joining Ken Griffey Jr. (and later Yoenis Céspedes and Pete Alonso) as the only players to win more than one derby and becoming the first player to win the Derby as both an American League (AL) and NL All-Star.
On August 10, 2016, Fielder announced that he would be unable to continue his playing career after undergoing a second neck surgery in three years. He was released by the Rangers on October 4, 2017. He ended his career with 319 home runs, the same number as his father, Cecil Fielder. Prince and Cecil Fielder are also the only father-son duo to each hit 50 MLB home runs in a season, and were the only father-son duo to hit 40 MLB home runs in a season until 2021, when Vladimir Guerrero Jr. joined his own father in achieving the feat.
