Dennis Eckersley, American baseball player and sportscaster

Dennis Lee Eckersley (born October 3, 1954), nicknamed "Eck", is an American former professional baseball pitcher and current New England Sports Network (NESN) part-time 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 MLB history to have both a 20-win season and a 50-save season in a career.

Eckersley was elected to the Baseball Hall of Fame in 2004, his first year of eligibility. He currently works with New England Sports Network (NESN) as a part-time color commentator for Red Sox broadcasts, and has also worked for Turner Sports as a game analyst for their Sunday MLB Games and MLB Post Season coverage on TBS.
