The 2023 Major League Baseball season (MLB) began on March 30.^[1] The 93rd All-Star Game was played on July 11, hosted by the Seattle Mariners at T-Mobile Park in Seattle, Washington, with the National League winning, 3–2.^[2] The regular season ended on October 1, and the postseason began on October 3, and ended with Game 5 of the World Series on November 1. This season saw the introduction of several rule changes: in an effort to create a quicker pace of play, a pitch clock was introduced along with other minor changes, while limits on defensive shifts and larger bases were also introduced.

On August 24, 2022, Major League Baseball released its 2023 schedule. There were 162 games scheduled for all teams. This season was the first MLB season of a new balanced schedule in which every team played each other at least once, similar to the NBA and NHL. The new balanced schedule included 13 games against their division rivals, totaling 52 games. Each team played six games against six opponents and seven games against four opponents in the same league for a total of 64 games. Each team also played 46 interleague games, including a four-game home-and-home series against their designated interleague rival.^[3]

As part of the "MLB World Tour", the San Francisco Giants and the San Diego Padres played a two-game series at Alfredo Harp Helú Stadium in Mexico City on April 29–30, while the St. Louis Cardinals and the Chicago Cubs played a two-game series at London Stadium in London on June 24–25. The 93rd All-Star Game was played on July 11, hosted by the Seattle Mariners at T-Mobile Park in Seattle.^[3] The MLB Little League Classic featured the Philadelphia Phillies against the Washington Nationals on August 20. The Nationals won the game 4–3.^[4]

Opening Day, March 30, featured all thirty teams, the first time since 1968 that every team has started their season on the same day.

The MLB at Field of Dreams game was not held in 2023 due to the construction of a new youth baseball and softball complex at the Field of Dreams site near Dyersville, Iowa.^[5]

On September 8, 2022, MLB announced a set of rules changes that would take effect in 2023.^[6]

• A pitch clock was introduced, with these requirements:
  • A standardized period of 30 seconds between batters within each half-inning.
  • A timer between pitches of 15 seconds with the bases empty, and 20 seconds with at least one runner on base.
  • The pitcher must start his motion before the expiration of the pitch clock. A violation will result in an automatic ball.
  • The batter must be in the box and alert to the pitcher with no less than eight seconds remaining. A violation will result in an automatic strike.
  • With runners on base, the timer resets if the pitcher attempts a pickoff or steps off the rubber (collectively called a "disengagement").
  • Only two disengagements are allowed per plate appearance; however, this count resets if a baserunner advances. Mound visits, injury timeouts, and offensive team timeouts do not count against this.
  • If a third disengagement results in anything other than a successful pickoff attempt, it is treated as a balk and all runners advance one base.
  • If a team has used up all of its allowed five mound visits by the ninth inning, it receives an extra visit in the ninth.
  • Umpires can provide extra time if circumstances warrant.
• Infield shifts are restricted:
  • The defensive team must have no fewer than four players in infield positions, with at least two on each side of second base.
  • All infielders must have both feet on or inside the outer edge of the marked infield while the pitcher is on the rubber.
  • Infielders cannot switch sides of the infield before a pitch is released.
  • If infielders are improperly aligned at the time of the pitch, the offensive team may choose to accept the result of the play or receive an automatic ball.
• All three bases will increase in size from 15 to 18 inches (38 to 46 cm).

Further changes were announced on February 13:^[7]

• In regular-season games, the WBSC softball extra innings rule is in effect, with each extra inning starting with a runner on second base. WBSC, the global governing body of baseball, implemented tiebreakers at international tournaments starting in 2008, and in MLB regular season play, was first used in the COVID-abbreviated 2020 season and again in the lockout-altered 2022 season.
• The rule that regulates when position players can pitch, was tweaked. Previously, position players were allowed to pitch when either team had a lead of at least six runs. Starting with this season:
  • The leading team can only use a position player in this role in the ninth inning and with a lead of at least 10 runs.
  • A team behind by eight or more runs can use a position player to pitch at any time in the game.
  • The use of position players as pitchers in extra innings is unrestricted, as it was under the previous rule.

Spring training for the 2023 season began in late February and lasted through March. Teams began workouts and practice for spring training beginning in late February. Pitchers and catchers reported first, followed by position players a few days later.^[8]

Prior to the start of the regular season, each team played between 27 and 33 spring training games, beginning on February 24. There were several times during spring training when a team had two different squads playing different teams simultaneously. In addition to spring training games, teams occasionally played exhibition games with non-MLB teams, such as Minor League Baseball teams, independent teams, or college teams. These exhibition games were not counted in the spring training standings. Spring training ended on March 28, two days before the Opening Day.

The Postseason began on October 3 and ended with Game 5 on November 1.^[9]

• The Rangers' City Connect uniform featured a mythical-like creature titled a Peagle, which represents the metro area's two minor league baseball teams before the arrival of the team, the Fort Worth Panthers and the Dallas Eagles.

• The Reds' City Connect uniform features a diamond-shaped "C" on the cap and the jersey sleeve. It also features the word "CINCY" (short for Cincinnati) across the chest.

• The Orioles' City Connect uniform features an italic "B" (commonly seen on the Orioles Road Jersey) on the cap and the sleeve of the jersey. For the jersey, it features the word "Baltimore" across the jersey. On the collar of the jersey, it features the colors and shapes of Baltimore's Neighborhoods.^[187]
• The Pirates' City Connect uniform features gold jerseys and black pants. The jersey features the abbreviation "PGH" across the chest with a checkered pattern influenced by the city seal that contains the symbols of an inverted "Y", representing the three rivers that meet in Pittsburgh (Allegheny, Monongahela, and Ohio), and the asteroid, or the diamond star shape, taken from the famous "Steelmark" logo.^[188]

Vince Cotroneo and Johnny Doskow have since shared play-by-play duties on the television booth to replace Kuiper.^[248]
• On July 25, Marquee Sports Network, the television home of the Chicago Cubs, launched an over-the-top subscription streaming platform that offers live streams of Cubs games without a cable subscription for $19.99 a month.^[249]

On February 24, 2023, the AT&T SportsNet regional sports networks sent a letter to the Rockies, Astros, and Pirates saying they had until March 31, to reach an agreement to take their local television rights back. Warner Bros. Discovery (WBD), the owner of the networks, intends to leave the regional sports networks business. If a deal is not reached the networks will file for Chapter 7 bankruptcy. Root Sports Northwest is not affected because the Mariners already own majority control of that network.^[250][251] Warner Bros. Discovery and Major League Baseball quietly negotiated a deal to keep the remaining RSNs operational through the end of the season.^[252]

In August 2023, Boston Red Sox owner Fenway Sports Group announced its acquisition of AT&T SportsNet Pittsburgh from WBD via the co-owned Pittsburgh Penguins of the NHL, which subsequently re-launched as the NESN-operated SportsNet Pittsburgh in October. During the offseason, the Pittsburgh Pirates announced they would jointly own the network beginning on January 1, 2024.^{[253][254][255]} In September 2023, the Houston Astros and Houston Rockets jointly acquired WBD's stake in AT&T SportsNet Southwest.^[256] Both of those networks rebranded themselves to SportsNet Pittsburgh and the Space City Home Network, respectively, near the end of the regular season. However, with AT&T SportsNet Rocky Mountain failing to find new owners (either with the Colorado Rockies or some other professional sports team(s) in the area), SportsNet Rocky Mountain shut down services by October 21, 2023.

On February 15, 2023, Diamond Sports Group, owners of the Bally Sports regional sports networks, failed to make a $140 million interest payment and entered a 30-day grace period.^[257] On March 14, Diamond Sports officially filed for Chapter 11 Bankruptcy.^[258] Diamond had missed payments to the Diamondbacks, Rangers, Guardians, and Twins.^{[259][260][261]} Diamond also entered grace periods for their payments to the Padres and Reds, which they eventually made.^[262][263] On April 5, Major League Baseball filed an emergency motion asking the bankruptcy judge to order Diamond to pay the teams they missed payments to or give the media rights back to MLB. Diamond argued that due to the impact of cord-cutting, the contract rate for the media rights of the teams was too high. A hearing on the matter was set for May 31.^{[264][261][259][265]} As an interim, on April 19, the bankruptcy judge ordered Diamond Sports to pay 50% of what the Diamondbacks, Guardians, Twins, and Rangers are owed.^[266] On June 1, after a two-day long hearing, the bankruptcy judge ordered Diamond to pay the teams fully within five days.^[267]

On May 31, Diamond officially missed a second payment to the Padres, and the Padres' television rights were returned to Major League Baseball. Because Bally Sports San Diego, which aired Padres games, is a joint venture between the Padres and Diamond it is technically not in bankruptcy. Therefore, this missed payment did not have the same bankruptcy protections that Diamond's other missed payments had.^[268][269]

MLB Local Media—a new department led by former Fox Sports Networks executive Billy Chambers^[270]—took over production and distribution of Padres telecasts the same day; Padres games would be available locally via ad-hoc channels on participating television providers in the San Diego area, and via an over-the-top subscription service hosted by MLB.tv.^[271][269] The department had already worked with MLB Network staff to prepare for the possibility that it would have to take over a team's regional broadcasts on short notice, including preparing team-specific graphics packages and other elements in advance. Chambers' team was on standby in Miami for the Padres' series against the Marlins, focusing in particular on contingencies for the May 31 game based on the deadline, and having only 24 hours' notice of the missed payment on May 30.^[272] The MLB-produced telecasts inherited the Padres' existing broadcast team and other team-contracted staff. Once the team returned to San Diego, MLB Local Media inherited the mobile production units and freelance employees that had been used by Bally.^[273]

On June 22, Diamond Sports Group announced its intention to reject its contract with the Diamondbacks on June 30.^[274] Diamond and the Arizona Diamondbacks later released a joint statement pushing back the hearing to July 17 and agreeing to continue Bally Sports Arizona's broadcasts of Diamondbacks' games.^[275] On July 18, Diamond Sports officially rejected its contract with the Diamondbacks; MLB Local Media subsequently took over production of the team's telecasts in a similar arrangement to the Padres.^{[276][277][278]} After losing the rights earlier in the year to the Phoenix Suns and later in the year to the Arizona Coyotes to Gray Television and Scripps Sports respectively, Bally Sports Arizona began to wind down operations in October 2023, shutting down for good on October 21 that same year.^[279]
