Born on December 21, 1960, in Cincinnati, Ohio, McDowell attended Bowling Green State University, where he honed his skills on the mound. His professional journey began when the Mets selected him in the third round of the 1982 MLB Draft.

McDowell made his MLB debut on April 11, 1985, with the New York Mets. His rookie season was impressive, as he quickly established himself as a reliable arm in the bullpen. That year, he appeared in 62 games, posting a 2.83 ERA and recording 17 saves. His performance helped the Mets contend for the National League East title, although they ultimately fell short.

The 1986 season was a highlight in McDowell's career. He played a crucial role in the Mets' bullpen, contributing to the team's successful campaign that culminated in a World Series championship.

Despite the changes in teams, McDowell continued to demonstrate his skills as a reliable reliever, contributing to each team's bullpen depth.

Throughout his career, McDowell was known for his sinkerball, which induced ground balls and helped him escape challenging situations.
