Michael D. Port is an American former professional baseball executive. He was vice president, Umpiring for Major League Baseball from August 2005 through March 2011, when he left that position, and previously was a front-office executive for three MLB clubs. Port was the general manager of the California Angels from September 1984 through 1991 and acting GM of the Boston Red Sox from February through November of 2002. After attending United States International University in his native Southern California, Port entered baseball in 1969 as a minor league second baseman for the newly minted San Diego Padres, but after an injury, he retired to become an executive in the San Diego organization. In 1973 he became the club's farm system director and moved to the Angels in a similar capacity in 1978. Port was also adept at the business side of baseball, and in 1980, he was promoted by the Angels to vice president and chief administrative officer. He succeeded Buzzie Bavasi, his boss in both San Diego and Anaheim, as the Angels' general manager late in 1984.
