Terry Jay Forster (born January 14, 1952) is an American former left-handed relief pitcher who played for 16 seasons in the Major Leagues.

He became Chicago's top relief pitcher in 1972 and saved 29 games, which ranked second in the American League that season.

[4] He then missed most of 1975 with an arm injury, which allowed teammate Rich Gossage to become the league leader in saves that season.

In 1976, new White Sox manager Paul Richards decided to put Forster in the starting rotation.

At the end of the season he was traded, along with Gossage, to the Pittsburgh Pirates in exchange for Richie Zisk[1] and Silvio Martínez.

The loss by the Dodgers propelled the Atlanta Braves to the 1982 National League West Division title.

David Letterman gave the left-hander national notoriety in 1985, when he referred to the lefty as a "fat tub of goo" on his Late Night show.
