Edward "Buddy" LeRoux, former part owner of the Red Sox and real estate baron, has died of natural causes. He was 77. LeRoux died Monday in a New Hampshire hospital, according to the Lord Funeral Home in Wolfeboro. LeRoux started as a trainer for the Red Sox from 1966-74. He served as the team's vice president from 1978-79, then became an owner as part of a group that included Haywood Sullivan and Jean Yawkey, widow of longtime team owner Tom Yawkey. He was forced to sell his share of the team after a failed attempt to wrestle control from Sullivan and Yawkey.
