Majority owners During the ownership tenure of Mrs. Jean R. Yawkey,
Haywood Sullivan and
Buddy LeRoux became general partners. A purchase of the team from the estate of Tom Yawkey was approved by the league in May 1978, resulting in each of Mrs. Yawkey, Sullivan, and LeRoux having a one-third controlling interest in the team as general partners. This stood until March 1987, when Yawkey bought out LeRoux, following a failed attempt by LeRoux to take control of the team. Mrs. Yawkey's majority ownership of the team passed upon her death in February 1992 to
JRY Trust, which later bought out Sullivan in November 1993.
