Doug Sisk, a right-handed relief pitcher, played in Major League Baseball primarily for the New York Mets and later for the Baltimore Orioles and Atlanta Braves. Born on September 26, 1957, in Renton, Washington, Sisk attended Washington State University, where he honed his skills on the mound before being drafted by the Mets in the second round of the 1980 MLB Draft.

Sisk made his MLB debut with the New York Mets on September 6, 1982. Known for his sinkerball, he quickly became a reliable option out of the bullpen. His pitching style was characterized by inducing ground balls, which helped him maintain a low earned run average (ERA) during his early years. In 1983, his first full season, Sisk appeared in 67 games, posting an impressive 2.24 ERA over 104.1 innings. His performance contributed to the Mets' improved standing in the National League.

The 1984 season saw Sisk continue his role as a dependable reliever. He pitched in 51 games, maintaining a 2.09 ERA, and was instrumental in the Mets' second-place finish in the National League East. His ability to keep the ball in the park and limit home runs was a valuable asset to the team's bullpen.

Sisk's career with the Mets reached its peak during the 1986 season when the team won the World Series. Although he struggled with control issues that year, posting a 4.88 ERA, he was part of a strong bullpen that supported the Mets' championship run. Despite not playing in the World Series, his contributions during the regular season were part of the team's overall success.

After the 1987 season, Sisk was traded to the Baltimore Orioles. His time with the Orioles was brief, as he struggled to find the same level of success he had with the Mets. In 1988, he appeared in 45 games, but his ERA rose to 5.25, and he was released by the Orioles at the end of the season.

Sisk signed with the Atlanta Braves in 1989, hoping to revive his career. Over two seasons with the Braves, he pitched in 66 games, but his performance remained inconsistent. His ERA during his tenure with Atlanta was 4.62, and he was released after the 1990 season.

In 1991, Sisk attempted a comeback with the New York Yankees, signing a minor league contract. However, he did not make it back to the major leagues and retired from professional baseball later that year.
