As Major League Baseball’s opening day approaches, so, too, does the official transfer in Orioles ownership. The Angelos family — longtime owners of the Orioles — agreed earlier this year to sell the club and its assets, valued at $1.725 billion, to a group led by Baltimore native and billionaire David Rubenstein. The sale of a controlling stake has received preliminary approval from a committee of MLB owners, but is awaiting formal approval from a full vote of owners.
