The 27-time World Series champion, which has held the top spot since Forbes began tracking MLB team finances in 1998, is worth $4.6 billion, the publisher said in a statement on Wednesday. The Los Angeles Dodgers ($3.3 billion), reigning World Series champion Boston Red Sox ($3.2 billion), Chicago Cubs ($3.1 billion) and San Francisco Giants ($3 billion) rounded out the top five. The average MLB team is now worth $1.8 billion, an 8 percent increase from last year, due in large part to a continued escalation in the value of the sport's media rights.
