Billionaire hedge-fund executive Steven Cohen is interested in buying the Dodgers, according to sources. Cohen has engaged notable sports architecture firms to propose renovations to Dodger Stadium, allied himself with one of baseball's power brokers, secured the support of at least two prominent Angelenos and met with several major league owners. He was joined in those meetings by Arn Tellem, an influential sports agent who could run the Dodgers if Cohen were to buy the team. Cohen is among the first bidders submitted to Major League Baseball for approval, according to a person familiar with the process. Initial bids are due Jan. 13. Cohen, 55, is the founder of SAC Capital Advisors, a Connecticut-based investment firm that controls $14 billion in assets. In September, Forbes estimated his net worth at $8.3 billion.
