Lee Guetterman, American baseball player
Arthur Lee Guetterman (born November 22, 1958), nicknamed "Goot," is an American former professional baseball pitcher who played from 1984 to 1996 for the Seattle Mariners, New York Yankees, New York Mets, and St. Louis Cardinals of Major League Baseball (MLB). A southpaw used primarily in the major leagues as a relief pitcher, he stood 6 feet 8 inches (2.03 m) tall. He led the Yankees in wins in 1990 without starting a game.

Guetterman attended Liberty University, where he set several school records on the baseball team. Drafted by the Mariners in the fourth round of the 1981 Major League Baseball (MLB) Draft, he made his major league debut in 1984, though he would not return to the major leagues until 1986. After having the highest earned run average (ERA) of any American League (AL) pitcher with at least 75 innings pitched in 1986, he won 11 games as a starter in 1987, posting an 8–1 record at one point before getting moved to the bullpen due to a loss of control of his pitches. He was traded to the Yankees after the season, and after spending much of 1988 in the minor leagues, he emerged as a part-time closer for the Yankees in 1989, while Dave Righetti was struggling. He had 13 saves in 1989, then just two the following year, though he would lead the Yankees in wins. In 1991, however, Guetterman became unhappy with his playing time and requested a trade, which he got in 1992, when he was part of the only Yankees-Mets trade between 1987 and 2001.

After finishing the 1992 season with the Mets, Guetterman pitched for the Cardinals in 1993, though he was in the minor leagues until June 30 that year. He had a 2.93 ERA for the Cardinals that year but did not return to the major leagues in 1994. After stints with the Mariners again in 1995 and 1996, Guetterman played one year for the Sioux Falls Canaries of the independent Northern League.
