Forbes said Wednesday it estimates the Yankees are worth $2.5 billion, up 9 percent from last year. The Dodgers are next at $2 billion, a 24 percent hike and matching their actual sale price in 2012.
Boston was third at $1.5 billion, followed by the Chicago Cubs ($1.2 billion), San Francisco ($1 billion) and Philadelphia ($975 million).
At the bottom were the Rays ($485 million), Kansas City ($490 million), Oakland ($495 million) and Miami ($500 million).
Major League Baseball's average team value rose 9 percent to $811 million. Forbes says values rose primarily because of increased media rights fees.
