Born on March 29, 1966, in Portland, Oregon, Gunderson attended the University of Portland, where he honed his skills as a left-handed pitcher. His talent on the mound caught the attention of scouts, leading to his selection by the San Francisco Giants in the 9th round of the 1987 MLB Draft.

Gunderson made his MLB debut with the Giants on September 8, 1990. During his time with San Francisco, he primarily served as a relief pitcher, a role he would continue to fill throughout much of his career.

With the Mariners, Gunderson had the opportunity to further develop his pitching repertoire, contributing to the team's bullpen depth.

In 1993, Gunderson joined the New York Mets, where he spent parts of two seasons. His time with the Mets was marked by steady performances, as he provided the team with a reliable left-handed option out of the bullpen. After his stint in New York, Gunderson's career took him to the Boston Red Sox in 1994. Although his time in Boston was brief, he continued to demonstrate his ability to adapt to different teams and pitching staffs.

The Texas Rangers became Gunderson's next destination in 1995. During his time with the Rangers, he continued to fulfill his role as a relief pitcher, offering his experience and skill to the team's bullpen. Gunderson's journey through the major leagues also included a period with the Toronto Blue Jays in 1996, where he once again contributed as a left-handed reliever.

In 1997, Gunderson signed with the Montreal Expos, adding another chapter to his diverse career. His experience and adaptability were valuable assets to the Expos' pitching staff. Gunderson's final MLB appearance came with the Expos on September 27, 1998, marking the end of his time in the major leagues.

Throughout his career, Eric Gunderson played for several teams, each time bringing his expertise as a left-handed pitcher to the bullpen.
