The Buss family is making news on two coasts of the sports map this week — buying into one franchise while a sibling fights in court to stop the sale of another.

Joey and Jesse Buss, sons of the late Lakers patriarch Dr. Jerry Buss, have joined the new ownership group of the San Diego Padres, the team confirmed Wednesday. Their investment vehicle, Buss Sports Capital, is taking roughly a 5% stake in the club, according to ESPN and the Associated Press.

The move comes on the heels of Jose E. Feliciano and Kwanza Jones closing their purchase of the Padres at a record $3.9 billion valuation, the highest price ever paid for an MLB franchise. Feliciano, co-founder of the private equity firm Clearlake Capital, and Jones, a singer-songwriter and entrepreneur, will lead the new group; the Buss brothers, who grew up in San Diego County, will sit on its advisory board.

"We are honored to join Kwanza and Jose and have the opportunity to contribute to the future of a team that Jesse and I have loved since we were kids growing up in San Diego," Joey Buss said in a statement, adding that "the Padres are on the cusp of something special."

Jesse Buss said he and his brother spent "nearly two decades building our own careers in professional basketball operations" after being trained by their father, and that the principles behind "building sustained success are universal" across sports.

A family split down the middle

The Padres windfall traces back to the Buss family's blockbuster sale of its majority stake in the Lakers to Dodgers owner Mark Walter last year, proceeds the brothers used to launch Buss Sports Capital. But the timing is awkward: their sister Jeanie Buss, the Lakers' governor since their father's death in 2013, is now suing to block the rest of the family from selling the remaining 17.8% of the franchise.

Five of the six Buss siblings voted to sell that stake to a group led by Disney chairman Bob Iger and venture investor Josh Kushner in a deal reportedly valuing the Lakers at $12.5 billion, per CNBC. Jeanie, represented by attorney Adam Streisand, filed a petition in Los Angeles Superior Court arguing her siblings cannot force the sale without her consent, and warning that completing it would drop her ownership share below the 15% the NBA requires to remain a controlling governor, according to Deadline.

Jeanie Buss doesn't want to sell the family's remaining stake, or her grip on the only job she's ever wanted.

Neither the Padres nor the Lakers camp has suggested the two situations are connected beyond the family ledger, but the split underscores how differently Jerry Buss's children are handling the fortune, and the legacy, he left behind. One faction is diversifying into a record-setting baseball deal; the other is digging in to keep the basketball dynasty their father built in 1979.
