The match is scheduled and broadcasters will confirm their final channel allocations closer to kick-off.

Major League Baseball is the top tier of professional baseball in North America, made up of 30 franchises in the American and National Leagues. Teams play a 162-game regular season before 12 sides enter the postseason, which culminates in the best-of-seven World Series in late October. Matches like Seattle Mariners vs Boston Red Sox can move table positions, decide qualification places and shape end-of-season storylines, which is why broadcaster coverage tends to grow as the campaign progresses.
