Scott Alan Eyre (born May 30, 1972), is an American former professional baseball left-handed pitcher, who played in Major League Baseball (MLB) for the Chicago White Sox, Toronto Blue Jays, San Francisco Giants, Chicago Cubs, and Philadelphia Phillies.

Eyre was born on May 30, 1972, in Inglewood, California. He was the oldest of five children in his family, born when his mother Peggy was only 17 years old. When Eyre was eight years old, his father Bob left the family and kept only marginal contact with his wife and children; Eyre was responsible for his younger siblings throughout their respective childhoods. Eyre’s undiagnosed attention deficit hyperactivity disorder (ADHD) made it difficult for him to pay attention in school, and he preferred playing sports, particularly baseball.
