Not according to the Cincinnati newspaper and the broadcasters last night on FOX sports Ohio during the Reds win.
Both sources say that TNT and TBS have exclusive rights and the World Series has NEVER been on any FOX RSN
And if you read my post, I said local Fox affiliates. In other words, the Fox Broadcast channel. RSNs have never had the LCS or WS. TBS only has divisional rounds. Look it up.
