Baker Botts, DLA Piper and White & Case are advising on the record-setting $2.2 billion sale of the National Basketball Association’s Houston Rockets from former lawyer Leslie Alexander to casino and hospitality billionaire Tilman Fertitta.

The deal, the news of which emerged Tuesday, represents the highest price ever paid for an NBA franchise, beating out the $2 billion that former Microsoft Corp. CEO Steve Ballmer paid for the Los Angeles Clippers in 2014. In July, the Rockets confirmed their decision to pursue a potential sale of the franchise.
