The 2020 Major League Baseball season was scheduled to begin on March 26. However, due to the coronavirus pandemic, on March 12 Major League Baseball (MLB) announced that the remainder of spring training games were cancelled and that the start of the regular season would be delayed by at least two weeks. Four days later, MLB announced that the season would be postponed indefinitely, following recommendations from the CDC to restrict events of more than 50 people for an eight-week period. This is the first time MLB games have been put on hold since the 2001 season, when the season was paused for over a week after the September 11 attacks.
Prior to the March 12 announcement, the regular season was scheduled to end on September 27, with the postseason scheduled to begin on September 29. The World Series was set to begin on October 20, with a potential Game 7 set to be played on October 28. The 91st Major League Baseball All-Star Game is scheduled to be held on July 14 at Dodger Stadium. The entire schedule had been released on August 12, 2019. MLB has considered a number of scenarios as to how to play the season, and has vowed to hold "as many baseball games in 2020 as we can."
As has been the case since 2013, the American League and National League each comprise 15 teams divided into three five-team divisions. Teams were scheduled to play 19 games against each of their four division opponents (76 games), plus six or seven games against the remaining ten teams within the same league (66 games). Thus, each team would have played 142 games against teams in their own league; the remaining 20 games of the 162-game schedule would be inter-league contests. The primary inter-league match-ups are to be AL East vs NL Central, AL Central vs NL West, and AL West vs NL East.
March 26 would have been the earliest Opening Day in Major League history. The 2019 season previously featured the earliest Opening Day (March 28), excluding occasional international opening series. The delay of the opening of the season negates that possibility.
The MLB Mexico Series was to feature the San Diego Padres against the Arizona Diamondbacks in a two-game series at the recently built Estadio Alfredo Harp Helú in Mexico City, Mexico on April 18–19. Major League Baseball canceled this series on March 19. If played, the series will be held in Phoenix and the Diamondbacks will be designated the "home" team.
The MLB Puerto Rico Series was to feature the New York Mets against the Miami Marlins in a three-game series at Hiram Bithorn Stadium in San Juan, Puerto Rico, on April 28–30. Major League Baseball canceled this series on March 19. If played, the series will be held in Miami and the Marlins will be designated the "home" team.
The New York Yankees and Chicago White Sox are scheduled to play on August 13 in the first MLB at Field of Dreams game. A temporary 8,000-seat ballpark will be constructed on the Dyersville farm site where the film Field of Dreams was filmed. This will be the first MLB game played in Iowa since 1875.
The MLB Little League Classic at BB&T Ballpark in Williamsport, Pennsylvania, coinciding with the Little League World Series, returned to the schedule for the fourth straight year. It is scheduled to be played on August 23 between the Boston Red Sox and Baltimore Orioles.
The indefinite delay of the 2020 season has caused MLB to internally consider a number of scenarios for playing the season, as well as analysts suggesting ways it could be done. A shortened regular season, a season with many doubleheaders, and a postseason extending into November with a World Series at an indoor or warm-weather neutral site have all been suggested.

This will be the Texas Rangers' first season at Globe Life Field, replacing Globe Life Park in Arlington where they played 26 seasons, from 1994 to 2019. The team will play its first regular-season game in their new venue against the Los Angeles Angels, originally on March 31, on a date to be determined after the pandemic hiatus.
The Miami Marlins will convert Marlins Park from a natural grass surface to the same artificial turf variety, Shaw Sports B1K, that the Arizona Diamondbacks installed at Chase Field in 2019. The field's fences will also be moved in closer to encourage power hitting.
This will be the seventh year of the current eight-year deals with Fox Sports, ESPN, and TBS.

FS1 will televise games on Tuesday night and on Saturday both during the afternoon and night. ESPN will televise games on its flagship telecast Sunday Night Baseball as well as Monday and Wednesday Nights. TBS will televise games on Sunday Afternoons for the last 13 weeks of the season.

In Chicago, new television deals resulted in the end of free-to-air regional telecasts for the city's two franchises. In February 2020, the Cubs launched the team-owned Marquee Sports Network, a joint venture with Sinclair Broadcast Group. The White Sox (as well as the Chicago Blackhawks of the NHL and Chicago Bulls of the NBA) signed exclusively with NBC Sports Chicago under a multi-year deal.
San Francisco Giants color commentator Mike Krukow and team broadcaster NBC Sports Bay Area announced that he would call 22 road games against NL West opponents from the network's San Francisco studios (using monitors and audio feeds to watch the game and communicate with his play-by-play partner Duane Kuiper). Krukow's inclusion body myositis has left him unable to travel with the team.
Due to the delay of the start of season due to the COVID-19 outbreak, the retirement ceremonies listed below will not happen until further notice.
