Silver Lake, a private equity firm, agreed to acquire Diamond Baseball, a professional development league business consisting of 10 Clubs, from Endeavor, a sports and entertainment company, for $280m. “Ultimately our relationship with MLB and the MLBPA took priority given the importance of our overall agency business and our continued investment in our baseball representation practice within WME Sports. Silver Lake will be an excellent partner to these Clubs going forward given their deep understanding of the business and their incredible track record of investment in sports IP," Mark Shapiro, Endeavor President.
