Gabe White's journey through Major League Baseball began when he was drafted by the Montreal Expos in the third round of the 1990 MLB Draft. A left-handed pitcher, White made his MLB debut with the Expos on June 27, 1994. His early career with Montreal saw him primarily in a relief role, where he demonstrated his ability to handle the pressures of the major leagues.

In 1995, White was traded to the Cincinnati Reds, where he continued to develop his skills as a relief pitcher. His tenure with the Reds was marked by steady performances, and he became a reliable option out of the bullpen. White's time in Cincinnati was interrupted by a brief stint with the Florida Marlins in 1997, but he returned to the Reds later that year.

The Colorado Rockies acquired White in 2000, and it was with this team that he experienced some of his most productive seasons. Pitching in the challenging environment of Coors Field, known for its hitter-friendly conditions, White managed to maintain a solid ERA and became an integral part of the Rockies' bullpen. His ability to perform in such a demanding setting was a testament to his pitching acumen.

In 2003, White was traded to the New York Yankees, where he joined a team with high expectations and a storied history. Although his time with the Yankees was relatively short, he contributed to their bullpen depth during the latter part of the season. White returned to the Reds in 2004, continuing to provide veteran leadership and experience to the pitching staff.

White's career came full circle when he rejoined the Rockies in 2005, his final season in the majors. Over the course of his career, he appeared in 460 games, all but six as a relief pitcher, and recorded a career ERA of 4.51. Known for his ability to handle both left-handed and right-handed hitters, White's role as a left-handed specialist was valued by the teams he played for.
