Dennis Lee Eckersley (born October 3, 1954), nicknamed "Eck", is an American former professional baseball pitcher and color commentator. Between 1975 and 1998, he pitched in Major League Baseball (MLB) for the Cleveland Indians, Boston Red Sox, Chicago Cubs, Oakland Athletics, and St. Louis Cardinals. Eckersley had success as a starter, but gained his greatest fame as a closer, becoming the first of two pitchers in major league history to have both a 20-win season and a 50-save season in a career.
