2025 Major League Baseball season

The 2025 Major League Baseball season began on March 18–19 with a two-game series between the defending World Series champion Los Angeles Dodgers and the Chicago Cubs held in Tokyo, Japan, before the regular season proper runs from March 27 to September 28. The 95th All-Star Game is planned for July 15 at Truist Park in Cumberland, Georgia, the home of the Atlanta Braves.
The Athletics relocated from Oakland to West Sacramento, California, for at least three seasons before their planned relocation to the Las Vegas metropolitan area. The team is branded as the Athletics, with no city name attached.
Major League Baseball released its 2025 schedule on July 18, 2024. There are 162 games scheduled for all teams. The scheduling formula was modified this season to increase the number of games between "prime" Interleague rivals from four to six, playing two three-game series instead of two two-game series. May 16–18 has also been designated as "Rivalry Weekend", featuring 11 series of these "prime" Interleague rivals.
The Los Angeles Dodgers and the Chicago Cubs opened the season at the Tokyo Dome in Tokyo on March 18–19 in the MLB Tokyo Series 2025. Opening Day in North America occurred on March 27 for all teams except for the Colorado Rockies and the Tampa Bay Rays, which was rescheduled to March 28 due to work done at the Rays' temporary ballpark Steinbrenner Field.
The 95th All-Star Game will be played on July 15, hosted by the Atlanta Braves at Truist Park in Cumberland, Georgia. The Atlanta Braves and Cincinnati Reds will play a game at Bristol Motor Speedway in Bristol, Tennessee, on August 2. The MLB Little League Classic at Bowman Field in Williamsport, Pennsylvania, will be played on August 17 with the Seattle Mariners taking on the New York Mets.
On January 25, 2025, MLB announced a set of rule changes to take effect during the season:
During spring training only, 13 stadiums were used to test the Automated Ball-Strike System (ABS). When ABS was available, teams had two challenges per game, retaining successful challenges. The batter, catcher, or pitcher could challenge a ball or strike call, but had to do so immediately and without assistance from anyone else.
This is the third year that teams added advertisement patches to their uniforms. The following teams have announced their uniform advertisements.
Eight teams unveiled new City Connect 2.0 uniforms and wore them for the first time during the season.
On November 16, 2023, MLB owners approved the Athletics' relocation from Oakland to Las Vegas. The Athletics then announced on April 4, 2024, that the team would temporarily play at Sutter Health Park in West Sacramento, California, from 2025 to 2027, with an option for 2028, while their new ballpark in Las Vegas is under construction.
Due to severe roof damage sustained at Tropicana Field caused by Hurricane Milton, the Tampa Bay Rays will play at George M. Steinbrenner Field, the New York Yankees' spring training stadium in Tampa.
Guaranteed Rate Field, home of the Chicago White Sox, was renamed to Rate Field during the offseason on December 17, 2024, as part of a rebrand of Guaranteed Rate.
Minute Maid Park, home of the Houston Astros, was renamed to Daikin Park during the offseason on January 1, after Japanese air conditioning manufacturer Daikin bought the naming rights.
This is the fourth year of the existing seven-year deals with Fox, TBS, and Apple TV+. This is also the fourth year of a deal with ESPN. However, ESPN and Major League Baseball announced prior to the season that both parties had exercised a mutual opt-out to end the agreement following the 2025 season. This is the second year of a multi-year deal with TelevisaUnivision.
During the postseason, the ESPN networks (including ABC, with Spanish–language simulcasts on ESPN Deportes) will air all four Wild Card Series. TNT Sports (TBS, truTV, and Max) will then broadcast the National League Division Series and the National League Championship Series, and Fox Sports (Fox and FS1, with Spanish-language simulcasts on Fox Deportes) will broadcast the American League Division Series, the American League Championship Series and the World Series.
