This guy was a heckuva pitcher for four years. His first good year was in 1975 with California (16-13, 2.91). He was traded to the Yankees along with Mickey Rivers for Bobby Bonds before the 1976 season. He had three more good years with the Yanks -- 19, 16, 20 wins, but went 0-4 in postseason play. In 1978 Ed was the first (and only) Puerto Rico-born pitcher to win 20 games.
Ed dropped to 4-6, 4.13 in 1979. He split 1980 between New York and Texas, going 3-10 with a 6.54 ERA. He was released by Texas after 1980 and hooked on with Oakland in 1981, but pitched only two games before calling it a career. He owns two restaurants in Puerto Rico now. Here is a "where are they now" article about Ed.
