Sam McDowell, a former pitcher for the Cleveland Indians and New York Yankees and a six-time All-Star, died Monday at the age of 84. KDKA in Pittsburgh reported his death.

McDowell, nicknamed "Sudden Sam," debuted in Major League Baseball at 18 in 1961 with the Cleveland Indians. The left-handed pitcher led the American League in earned run average in 1965 with a 2.18 mark and recorded a career-high 325 strikeouts that season. He went on to lead the league in strikeouts five times during his career.

He played for Cleveland for 11 years before joining the San Francisco Giants, the Yankees, and the Pittsburgh Pirates. Across his 15-year career, McDowell struck out 2,453 batters, ranking eighth on baseball's all-time list at the time of his retirement and 46th all-time as of recent records.

McDowell's career was cut short at age 32 in 1975 due to struggles with alcohol. He later described himself as "the biggest, most hopeless and most violent drunk in baseball." He recounted hitting rock bottom in 1978, broke and selling insurance, three years after being one of the game's most dominant pitchers.

In 1978, McDowell entered an alcohol rehabilitation program. He returned to college and became a licensed therapist specializing in sports psychology and addictions. He worked with the Texas Rangers and Toronto Blue Jays and served as the Baseball Assistance Team’s addiction and recovery consultant from 1987 to 2016, counseling numerous athletes struggling with substance abuse.

He also repaid over $190,000 in debt, a process he initiated by writing to each creditor and fulfilling his promise to pay them back by 1988.

McDowell reflected on his struggles and recovery, stating, "I truly believe with all my heart, the greatest thing that ever happened to me was that I was an alcoholic and found out about it. Had I never known and had not been thrown out of baseball, I would not have the great life I have now."

His memoir, "The Saga of Sudden Sam: The Rise, Fall, and Redemption of Sam McDowell," was published in 2022.
