Edmund Walter Lopat (originally Lopatynski) (June 21, 1918 – June 15, 1992) was a Major League Baseball pitcher.
Lopat was born in New York, New York. His Major League debut was on April 30, 1944, playing for the Chicago White Sox.
He was traded to the New York Yankees on February 24, 1948 for Aaron Robinson, Bill Wight, and Fred Bradley. From 1948 to 1954 he was the third of the "Big Three" of the Yankees' pitching staff, together with Allie Reynolds and Vic Raschi. He pitched in the All-Star Game in 1951 for the American League. In 1953 he led the AL in both earned-run average and won/lost percentage.
On July 30, 1955, he was traded to the Baltimore Orioles for Jim McDonald and cash, finishing out the season and retiring. Over his 12-year AL career, Lopat won 166 games, losing 112 (.597) with an ERA of 3.21.
Lopat managed the AAA Richmond Virginians for the Yankees in the late 1950s, and in 1960 served one season as the Yankees' pitching coach before holding the same post with the Minnesota Twins in 1961 and the Kansas City Athletics in 1962. In 1963 Lopat was tapped to manage the Athletics and continued in this role until June 11, 1964. His Major League managerial record was 90-124 (.421). Lopat stayed on as a senior front office aide to team owner Charlie Finley until the club moved to Oakland after the 1967 season.
He was sometimes known as "The Junk Man," but better known as "Steady Eddie.", a nickname later given to Eddie Murray.
He died at his son's home in Darien, Connecticut, and had been a resident of Hillsdale, New Jersey until his death.
Lopat pitched for five victorious Yankees teams in the World Series during his career, in 1949-1953.
