Dodgers' and Mets' issues are well-known but others are said to carry debt 10 times more than annual earnings.

Frank McCourt, the Dodgers' owner, has told executives within the industry he does not agree with Selig's decision to appoint a trustee to oversee his team and does not understand why Selig has not acted similarly with any other team.

"I can't say I haven't heard people in baseball talk about that," Chicago-based sports business consultant Marc Ganis said, "but there is a lot of deferral to Bud on this one."

Selig often says baseball is in a "golden age," in large part because revenue has jumped from $3.6 billion in 2002 — the last year seriously threatened by a strike or lockout — to $7 billion in 2010.

The debt service rules emerged from the 2002 labor negotiations, after overall club debt soared from $600 million in 1993 to $2.1 billion in 1999 and $3.1 billion in 2001.

The rules, intended to ensure clubs have the resources to support their financial obligations, generally limit a team's debt to 10 times its annual earnings, although Selig has wide latitude to enforce those rules.
