## Schedule

As was the case in 2014, teams were scheduled to play 19 games against each division opponent for a total of 76 games, and six or seven games against each team from the other two divisions in its league for a total of 66 games.
All teams were scheduled to play 20 interleague games throughout the season. For 2015, the interleague matchups were AL East vs. NL East, AL Central vs. NL Central, and AL West vs. NL West. Since "natural rivalry" matchups will be part of the three-year divisional rotation (for the first time), the schedule format for interleague games was different from previous years. The 20 interleague games each team played consisted of two three-game series (one home, one away) against its natural rival (total of six games), two two-game series (one home, one away) against each team for two other opponents (total of eight games; one of the matchups took place back-to-back within the same week), and a single three-game series against each team for the last two (one home, one away; total of six games).
During the final day of the regular season, all games were scheduled to start simultaneously at 3:00 p.m. Eastern Time, reminiscent of the English Premier League's last-day "Survival Sunday" scheduling. MLB hoped that this would add excitement and drama during the final day, and also limit teams' ability to rest starters at the last minute based on early game results.

* Mike Fiers (HOU)/(MIL):
** Threw his first career no-hitter in defeating the Los Angeles Dodgers 3–0 on August 21. This was the 11th no-hitter in Astros franchise history.

* Jake Arrieta (CHC):
** Threw his first career no-hitter in defeating the Los Angeles Dodgers 2–0 on August 30. This was the 14th no-hitter in Cubs franchise history. Arrieta struck out 12 batters and walked one while throwing 116 pitches.

## Television
### National
#### United States

2015 marks the second year of MLB's eight-year deal with Fox Sports, ESPN, & TBS. Fox will televise Saturday night games for eight consecutive weeks, leading up to the All Star Game, which will also air on Fox. Fox will then televise Saturday afternoon games for the last four weeks of the regular season. Fox Sports 1 will televise games on Tuesday nights and Saturdays, both during the afternoon and at night. ESPN will televise games on its flagship telecast, Sunday Night Baseball, as well as Monday and Wednesday nights. TBS will televise Sunday afternoon games for the last thirteen weeks of the regular season. Fox and ESPN Sunday Night Baseball telecasts will be exclusive; all other national telecasts will be subject to local blackout.
TBS will televise the National League Wild Card Game, Division Series, and Championship Series. ESPN will televise the American League Wild Card Game, Fox Sports 1 and MLB Network will televise American League Division Series, and Fox and Fox Sports 1 will televise the American League Championship Series. The World Series will air exclusively on Fox for the sixteenth consecutive year. All postseason games will air on ESPN Radio.

#### Canada

2015 was the second year of MLB's eight-year contracts for national broadcasts in Canada. Rogers Communications-owned Sportsnet holds English-language rights to the All-Star Game and Home Run Derby, almost all postseason games, and various regular season games, all of which are in addition to the channel's Canada-wide "regional" deal for all regular season games of the co-owned Toronto Blue Jays.
With the Blue Jays reaching the postseason in 2015 for the first time since 1993, Sportsnet president Scott Moore announced the channel was unable to produce separate Canadian telecasts of the Blue Jays' postseason games, and picked up the U.S. network telecasts of these games as it typically did for its postseason coverage. As in 2014, when the two Division Series games carried by MLB Network in the U.S. was also exclusive to that channel in Canada despite very limited carriage, Game 3 of the Royals-Astros ALDS was exclusive to MLBN in both countries. However Sportsnet aired all games of the Blue Jays-Rangers ALDS in Canada (MLBN carried Game 2 in the United States).
TSN holds English-language rights to most regular season games in ESPN's U.S. package. French-language rights are split between RDS and TVA Sports.

### Local

The Chicago Cubs opted to re-negotiate their terrestrial television contracts for the 2015 season through 2019, when all the Cubs' television rights contracts will expire, including their cable deal with Comcast SportsNet Chicago. WGN-TV will still hold rights to 45 Cubs games per season, and its overflow broadcasts will move to WPWR-TV in place of WCIU-TV. WGN will be joined by ABC-owned station WLS-TV, which will now broadcast 25 games per season. Broadcast Cubs games among the three stations in the market, along with White Sox games (which will also have games move from WCIU to WPWR) will be carried in the Indianapolis market among Media General's duopoly of WISH-TV and WNDY-TV, in addition to a regional network in Iowa and downstate Illinois.
The cable network WGN America will no longer carry Chicago White Sox or Chicago Cubs games, as the network has phased out Chicago sports programming as part of its transition towards becoming a nationally focused entertainment network. This brings an end to the "superstation" era of cable broadcast, started in 1976 when WTCG (later to become WTBS) broadcast Atlanta Braves games, followed by WGN and other stations such as WOR-TV (New York Mets), WSBK-TV (Boston Red Sox) and KTLA (California Angels) airing simulcasts via satellite or cable.
After an absence of over a decade, New York Yankees telecasts will return to WPIX, sharing time with the Mets after WWOR-TV gave up its contract due to the rejection of a contract extension. Both teams' games on WPIX will still be produced by the YES Network and SportsNet New York respectively.

## Radio

ESPN Radio aired its 18th season of national coverage, including Sunday Night Games, Saturday games, Opening Day and holiday games, the All-Star Game, and Home Run Derby, and the entire postseason.

### Local
