Larry Lucchino, the former president and CEO of the Boston Red Sox who oversaw three World Series titles during his tenure, has died, the team announced Tuesday. He was 78.

Lucchino became CEO of the Red Sox upon purchase of the team by the ownership group headed by John Henry and Tom Werner in February 2002. Lucchino, who stepped down from his role in 2015, had a smaller financial stake. He previously served as president/CEO of the Baltimore Orioles (1989-93) and San Diego Padres (1995-2001).
