Warner Bros. Discovery Sports is a little more than a month away from unwinding almost all of its regional sports network business.

When the current baseball season ends, WBD Sports is set to sell its RSNs in Pittsburgh and Houston to some of the teams in those markets and all signs point to the shuttering of its Denver-based channel, AT&T SportsNet Rocky Mountain.

Soon after the Oct. 1 conclusion of the MLB season, WBD Sports’ only RSN asset will be a 29% stake in the Seattle-based Root Sports Northwest. The Seattle Mariners have been the majority owner of that RSN since 2013.

WBD Sports already has agreed to a deal to allow Fenway Sports Group, which owns the Pittsburgh Penguins, to take over AT&T SportNet Pittsburgh. Specific financial details about the deal are not known, but it is expected to close within the next several weeks.

Fenway Sports Group has a lot of experience in the RSN business, as it co-owns one of the country’s most successful regional sports networks in NESN. The deal to take over the RSN ensures that the Penguins will remain on linear television in the Pittsburgh market.

It’s likely that Fenway Sports will launch a direct-to-consumer service around the Penguins, especially considering that NESN launched one around the Red Sox last year. But nobody is prepared to offer specifics about how a Fenway Sports-owned RSN will look in Pittsburgh.

Bankrupt Diamond Sports Group has sued its parent company Sinclair Broadcast Group (SBGI.O) for fraudulently withdrawing as much as $1.5 billion from the regional sports business, according to a lawsuit made public on Wednesday.

Diamond Sports, which broadcasts nearly half of NBA, NHL and MLB local games through its “Bally Sports” branded channels, said that Sinclair began siphoning the company’s assets away almost immediately upon acquiring it in 2019. Sinclair’s actions defrauded Diamond and its creditors, because Sinclair knew that Diamond was “careering toward bankruptcy” due to declining revenue from cable and satellite television subscriptions, according to the lawsuit.

“Throughout this entire period of precipitous decline, Sinclair unrelentingly continued to carry out its plan to ‘milk’ Diamond for Sinclair’s own benefit and to extract whatever value it could salvage before Diamond’s inevitable bankruptcy,” Diamond wrote in a complaint filed in U.S. bankruptcy court in Houston, Texas.
