Felix Heredia was a left-handed pitcher who played in Major League Baseball for over a decade. He was born on June 18, 1975, in Barahona, Dominican Republic. Heredia began his professional baseball career in 1993 when he signed with the Florida Marlins as an amateur free agent. He spent several years in the minor leagues before making his MLB debut with the Marlins in 1996.

Over the course of his career, Heredia played for several different teams, including the Marlins, the Montreal Expos, the Cincinnati Reds, the Chicago Cubs, and the New York Yankees. He was primarily used as a relief pitcher, although he did make some starts early in his career.

Heredia's best season came in 2003 when he was pitching for the Cubs. He appeared in 69 games that year and posted a 1.26 ERA with 47 strikeouts in 50 innings pitched. He was a key member of the Cubs' bullpen that season, helping the team win the National League Central division title.

Despite his success in 2003, Heredia struggled in the following seasons. He bounced around between several different teams and was never able to recapture the form he showed earlier in his career. He last played in the majors in 2005, appearing in just 14 games for the Yankees before being released.

Overall, Heredia's career statistics are fairly modest. He finished with a career record of 25-23 and a 4.28 ERA. He struck out 326 batters in 406 innings pitched. While he was never a star player, Heredia was a reliable left-handed reliever who was able to carve out a long career in the majors.
