More than two months after José E. Feliciano and Kwanza Jones agreed to buy the San Diego Padres at a record $3.9 billion valuation, Major League Baseball has not yet voted to approve the pending sale. The delay stems at least in part from the work of assembling an ownership structure that satisfies the league’s requirements for how private-equity institutions can hold a stake in a team, according to people briefed on the process who were granted anonymity in exchange for their candor.MLB commissioner Rob Manfred, speaking Tuesday at his annual All-Star Game press conference, said the sale was awaiting the buyers’ finalized investment commitments and the documentation needed for an owners’ vote. Manfred said he was not aware of any holdup “legally or otherwise,” but he also described the league as essentially a passive party waiting on the buyer and the seller.“It’s a question of getting investment commitments nailed down, documentation in a condition that it’s ready for a club vote,” Manfred said, adding that the sale price had become public earlier than is typical.“This one was earlier, quicker than sometimes happens. Usually, it gets public when they’re a little closer to final documents. But they’ll get that work done.”The Padres announced May 2 that the Seidler family had agreed to transfer control of the franchise to a group led by Feliciano and Jones, a deal that must be approved by at least 22 of 29 MLB owners. Feliciano and Jones, a husband-wife duo, plan to take a controlling stake of between 40 and 42 percent, a person familiar with the sale process told The Athletic on Tuesday, with several other individuals or entities expected to join their incoming group at a smaller combined percentage.
