Patrick Soon-Shiong said he would be interested in leading an investment group to buy the Dodgers if Mark Walter decides to sell, despite repeated assurances that the team is not currently on the market. The Dodgers, described as the crown jewel of Walter’s sporting empire, could be valued at $10 billion to $13 billion, according to an industry source cited by The Times. Soon-Shiong and Steve Cohen previously lost to Walter’s group in the 2012 sale, bidding $1.6 billion against the winning $2.15 billion offer. Walter’s sale of the Lakers for a reported $12.5 billion valuation has followed a cash crunch linked to federal and insurance-regulatory investigations into transactions involving entities he controls. No charges have been filed, and the investigations may conclude without charges.
