From Michael Hiestand of USA Today:

MLB will stay put with its current national broadcasters as it has agreed to new long-term deals with Fox and Turner Sports, person familiar with the deals told USA TODAY Sports on condition of anonymity until a public announcement is made.

The deals running through 2021, along with MLB’s recent long-term deal with ESPN, are significant in that MLB represented one of the last available marquee TV sports properties on the market. Most marquee sports are already locked into long-term deals.

From Richard Sandomir of the NY Times:

The new rights will push Fox to pay substantially more than the average of $257 million annually that it pays under its current contract, which ends after next season. ESPN agreed recently to an eight-year deal through 2021 worth $5.6 billion, doubling its average yearly payments to $700 million.

The transaction would let Fox carry two division series and add more regular-season games to its roster of Saturday games, the World Series, the All-Star Game and one league championship series. Fox plans to put some of the added games on Fox Sports One, a retooled version of its Speed channel.

TBS is to carry only 13 Sunday afternoon games under the new contract, down from 26, and two division series, down from the four it has been showing since 2007.

TBS will also retain one league championship series in the new deal and has gotten extensive new digital rights that will help its newly acquired Bleacher Report site. Also, its Sunday games will no longer be blacked out in the markets of the two teams that are playing. It also has one wild-card game.

In all, baseball’s annual payments from ESPN, Fox and TBS from 2014 to ’21 are expected to grow to $1.55 billion from $750 million in the current contract.
