Sosa played with four Major League Baseball teams over his career, which spanned from 1989 to 2007.
Sosa's Major League career began with the Texas Rangers in 1989.
After three seasons with the Chicago White Sox, Sosa became a member of the Chicago Cubs in 1992 and became one of the league's best hitters.
In 1998, Sosa and Mark McGwire achieved national fame for their home run-hitting prowess in pursuit of Roger Maris' home run record.
Sosa finished his career with brief stints with the Baltimore Orioles and the Texas Rangers.
With the Rangers, Sosa hit his 600th career home run to become the fifth player in MLB history to reach the milestone.
He is also the all-time home run leader among foreign-born MLB players.

Sosa is the only player to have hit 60 or more home runs in a single season three times.
