2022 Major League Baseball season

The 2022 Major League Baseball season (MLB) was originally scheduled to begin on March 31 and end on October 2. The 2021–22 lockout caused the season to be delayed by one week, starting on April 7. The regular season ended on October 5. The start of the season was delayed by a lockout of players, which commenced on December 2, 2021, following the expiration of the collective bargaining agreement (CBA) between the league and the Major League Baseball Players Association (MLBPA). On March 10, 2022, MLB and the MLBPA reached a deal on a five-year CBA, with Opening Day being held on April 7 (delayed from its originally planned March 31), and a full 162-game schedule played. Under the new CBA, universal designated hitter was adopted, the postseason was expanded to 12 teams, and the regular season tie-breaker game was eliminated. In November 2021, the Cleveland Indians announced their new team name, the Cleveland Guardians. The 2022 MLB All-Star Game was held on July 19 and hosted by the Los Angeles Dodgers at Dodger Stadium in Los Angeles.

Lockout
On December 2, 2021, MLB owners voted unanimously to enact a lockout upon the expiration of the 2016 collective bargaining agreement between the league and the players' union. Issues raised between the league and union involved compensation for young players, as well as limitations on tanking to receive higher selections in the MLB draft.

The 2021–22 lockout was the first MLB work stoppage since the 1994–95 strike. It instituted a transaction freeze, including the postponement of the major league portion of the Rule 5 draft. It would be the first year since 1920 to not have a major league phase of the Rule 5 draft, though the minor league phase will still go ahead as scheduled.

On March 10, 2022, almost 100 days after the beginning of the lockout, MLB and the MLBPA reached a deal on a new, five-year CBA. Players began reporting to training camps on March 11, spring training began on March 17, and Opening Day on April 7. The league planned to play a full, 162-game season, and games displaced by the delayed start have been rescheduled.

Changes in the new CBA include a pre-arbitration bonus pool for eligible young players, increased minimum salaries (increasing from $700,000 to $780,000 over the length of the deal), a draft lottery to determine the top six selections in the draft, the establishment of an international draft, and the establishment of a Joint Competition Committee that, in 2023, will oversee the adoption of future rule changes (including base sizes and pitch clocks among others). The National League began adopting the designated hitter on a permanent basis, after having previously used it on a temporary basis during the shortened 2020 season, while the postseason will be expanded to 12 teams.

Schedule
Major League Baseball released its 2022 regular season schedule on August 4, 2021. As has been the case since 2013, all teams play their four division opponents 19 times each for a total of 76 games, play six or seven games against each of the other ten same-league opponents for a total of 66 games, and 20 interleague games. Interleague play will feature AL East vs. NL Central, AL Central vs. NL West, and AL West vs. NL East.

The MLB at Field of Dreams game returned for a second year, featuring the Chicago Cubs and the Cincinnati Reds at the purpose-built ballpark in Dyersville, Iowa, on August 11. The Cubs won the game 4–2.

The annual MLB Little League Classic featured the Boston Red Sox and the Baltimore Orioles at Bowman Field in Williamsport, Pennsylvania, on August 21. The Orioles won the game 5–3.

Both Canada and the United States have travel restrictions for individuals who are not vaccinated against the SARS-CoV-2 virus that causes COVID-19. Each requires incoming travelers who are not citizens to have received a full course of an approved COVID-19 vaccine no later than 14 days before entry into the respective country.

Rule changes
On March 10, Major League Baseball announced the following rule changes for the 2022 season:
 * The temporary rule for the 2020 and 2021 seasons that had doubleheaders played as seven-inning games was repealed.
 * The National League adopted the designated hitter full-time. The NL previously adopted the rule temporarily in 2020 before removing it for the 2021 season.
 * Tie-breaker games at the end of the season have been eliminated and replaced with statistical tiebreakers.
 * The playoff system has been changed:
 * Twelve teams qualify for the postseason, with the division winners seeded 1 through 3, and three wild cards seeded 4 through 6 in their respective leagues.
 * The top two seeds in each league will receive a bye into the Division Series.
 * The lowest-seeded division winner and three wild card teams (each seeded according to regular season record), will play a best-of-three Wild Card round, with the higher seed hosting all three games. The 3-seed will play the 6-seed, and the 4-seed will play the 5-seed.
 * There is no re-seeding of the bracket. The 1-seed will play the winner of the 4-seed/5-seed series, and the 2-seed will play the winner of the 3-seed/6-seed series in the Division Series.

On March 22, MLB introduced a set of temporary rules for 2022:
 * If a team voluntarily waives the designated hitter spot so that its starting pitcher can be in the batting order, that pitcher can remain in the game as a designated hitter after being replaced by a relief pitcher. This was colloquially called the "Ohtani rule" after rare two-way player Shohei Ohtani.
 * The rule establishing an automatic runner on second base to start each extra inning in regular season games, previously repealed on March 10, was reinstated.
 * Rosters were expanded from 26 players to 28 players until May 2, due to the shortened spring training.

On April 5, the league announced that all teams may use PitchCom, a wireless system for catchers to request pitches by type and location. PitchCom is intended to reduce the risk of sign stealing and to quicken the pace of play.

On April 26, the league announced that limiting rosters to 13 pitchers had been delayed until May 30, allowing teams to carry up to 14 pitchers until then. The 13-pitcher limit was later delayed again, becoming effective June 20.

Spring training
Spring training for the 2022 season began later than usual due to the lockout, beginning in mid March and lasted into early April. 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.

Prior to the start of the regular season, each team played between 14 and 22 spring training games, beginning on March 17. Games were initially supposed to begin on February 27. There were several times during spring training where a team had two different squads playing different teams simultaneously. Due to the lockout, the usually occasional exhibition games with non-MLB teams, such as Minor League Baseball teams, independent teams, or college teams did not occur. Spring training ended on April 6, the day before the Opening Day.

Postseason
The postseason began on October 7, and ended on November 5.

No-hitters

 * Tylor Megill/Drew Smith/Joely Rodríguez/Seth Lugo/Edwin Díaz (NYM):
 * The five pitchers combined to throw the second no-hitter in franchise history by defeating the Philadelphia Phillies 3–0 on April 29. It was accomplished with 12 strikeouts and six walks on 159 total pitches. Megill pitched the first five innings. It is the 17th combined no-hitter in league history. This was also the 20th time that the Phillies have been no-hit in their history, which ties them with the Los Angeles Dodgers for the most times being no-hit of any franchise, which includes the postseason.
 * Reid Detmers (LAA):
 * Detmers threw his first career no-hitter, and the 12th no-hitter in franchise history, by defeating the Tampa Bay Rays 12–0 on May 10. He struck out two, throwing 68 strikes on 108 pitches. His only two baserunners came via a walk in the sixth inning and a fielding error in the seventh. Making his 11th career start, Detmers became the 25th rookie and youngest Angels pitcher in history to throw a no-hitter.
 * Cristian Javier / Héctor Neris / Ryan Pressly (HOU):

 * Cristian Javier / Bryan Abreu / Rafael Montero / Ryan Pressly (HOU):
 * The four pitchers combined to throw a no-hitter against the Philadelphia Phillies, defeating them 5–0 on November 2 in Game 4 of the World Series. It was only the second no-hitter in World Series history (the other being Don Larsen's perfect game in Game 5 of the 1956 World Series for the New York Yankees against the Brooklyn Dodgers), the third no-hitter in postseason history overall and first since Roy Halladay's no-hitter in Game 1 of the 2010 NLDS for the Phillies against the Cincinnati Reds, and the first combined no-hitter in postseason history.

Other pitching accomplishments

 * Justin Verlander (HOU):
 * Became the 138th pitcher in Major League history to amass 3,000 career innings pitched during the game against the Seattle Mariners on April 16.
 * Hunter Greene / Art Warren (CIN):
 * Combined to throw an eight-inning no-hitter on May 15 in the loss to the Pittsburgh Pirates 1–0. Because they did not pitch nine innings, it is not counted as a no-hitter by the Elias Sports Bureau, the official statistician of Major League Baseball.
 * Luis García / Phil Maton (HOU):
 * Became the first pair of pitchers in Major League history to throw an immaculate inning on the same date, let alone the same game or by the same team against the Texas Rangers on June 15. They both struck out Nathaniel Lowe, Ezequiel Duran and Brad Miller.
 * Madison Bumgarner (AZ):
 * Recorded his 2,000th career strikeout by retiring Luke Voit of the San Diego Padres in the fourth inning on June 22. He became the 86th pitcher to reach this mark.

 * Set the Major League record for most strikeouts by a pitcher through 200 career starts at 1,523 on August 7 against the Atlanta Braves. deGrom eclipsed the record of 1,517 that was held by Yu Darvish.
 * Set a new Major League record by recording his 40th straight start with three earned runs or fewer allowed against the Pittsburgh Pirates on September 18, breaking the record held by Jim Scott in 1913–14. deGrom's streak was snapped on September 24 by the Oakland Athletics as deGrom gave up four earned runs in the first inning.
 * Edwin Diaz (NYM):
 * Recorded his 200th career save by closing out a victory against the Philadelphia Phillies on August 13. He became the 53rd player to reach this mark.
 * Dylan Cease (CWS):
 * Cease went 14 consecutive starts allowing one run or fewer earned runs beginning on May 29 against the Chicago Cubs and through the August 11 game against the Kansas City Royals. It was the first time a starting pitcher went on such a streak since the earned run became a statistic in 1913, breaking the previous mark of 13 consecutive starts set by Jacob deGrom in 2021.
 * George Kirby (SEA):
 * Started the game against the Washington Nationals on August 24 with 24 straight strikes, setting a Major League record for most consecutive strikes to start a game since 1988, when pitch-tracking began. He broke the record that was set by Joe Musgrove in 2018 with 21 straight strikes.
 * Zac Gallen (AZ):
 * On September 4 against the Milwaukee Brewers, Gallen pitched seven scoreless innings. This was his sixth consecutive start where he pitched six or more scoreless innings, which tied the Major League record in the Modern Era (since 1900) as the fourth pitcher to accomplish this feat. He joins Don Drysdale (1968), Orel Hershiser (1988) and Zack Greinke (2015).
 * Framber Valdez (HOU):
 * With his six-inning two runs allowed performance on September 18, Valdez set the Major League record for most consecutive single-season quality starts with 25, breaking the record that was set by Jacob deGrom in 2018. The record for most consecutive quality starts is 26 held by deGrom (2018–19) and Bob Gibson (1967–68). The streak was stopped on September 24 by the Baltimore Orioles as Valdez only went $5 1/3$ innings giving up four earned runs.
 * Spencer Strider (ATL):
 * On September 18, Strider became the fastest pitcher in Major League history to amass 200 strikeouts in a season. Strider accomplished this feat in 130 innings, breaking the record set by Randy Johnson in 2001 in $130 2/3$ innings.
 * Max Scherzer (NYM):
 * Recorded his 200th career win on September 19 against the Milwaukee Brewers. He became the 120th player to reach this mark. He threw six perfect innings in that game before being taken out; his fourth career game to begin with six perfect innings ties the expansion era record.
 * Richard Bleier (MIA):
 * Became the first pitcher in Major League history to balk three times in the same at-bat on September 27. He had no balks in his first 303 career games.

 * Pittsburgh Pirates:
 * With their 1–0 win over the Cincinnati Reds on May 15, the Pirates became the sixth team since 1901 to win a game, despite being no-hit. However, the Reds only pitched eight innings, so it is not officially counted as a no-hitter by the Elias Sports Bureau.

 * Shohei Ohtani (LAA):
 * Ohtani became the first player in Major League history ever with 10 pitching wins and 30 homers in the same season, reaching the latter mark on August 31 with a homer against the New York Yankees. This also made Ohtani the first Japanese-born player with multiple 30-homer seasons.

 * New York Mets:
 * Set the modern-day (since 1900) record for most hit-by-pitch in Major League history when Luis Guillorme was hit in the ninth inning on September 21 against the Milwaukee Brewers. The Mets have been hit 106 times, breaking the record that was set by the Cincinnati Reds last year.

 * Cleveland Guardians / Tampa Bay Rays:
 * Set a Major League postseason record with 39 combined strikeouts: Tampa Bay with 20 and Cleveland with 19 in Game 2 of the ALWCS on October 8.

National
The 2022 season marked the first season of multiple broadcasting deals in Major League Baseball in the United States, most of which run through the 2028 season:


 * Fox remains the league's main broadcaster, carrying a package of regular season games on the main Fox broadcast network and FS1, and Spanish-language broadcasts on Fox Deportes. Fox aired primetime Baseball Night in America games primarily on Saturday nights, as well as the All-Star Game and MLB at Field of Dreams games. With the move of Joe Buck to ESPN and Monday Night Football over the NFL offseason, Joe Davis became the new lead play-by-play announcer for Fox's MLB coverage.
 * ESPN networks carry 30 exclusive games per season, including 25 Sunday Night Baseball games, as well as an Opening Day primetime game, the Home Run Derby, and Spanish-language broadcasts on ESPN Deportes. ESPN dropped most of its weeknight game packages under its new contract, with only five non-Sunday games scheduled. ESPN has the option to carry selected games on ABC and stream all of its games on ESPN+ (which, as before, carries a daily game from MLB.tv at no additional charge). ESPN+ games are also available to commercial establishments on the ESPN+ for Business package via DirecTV.
 * Apple Inc. established a new exclusive package known as Friday Night Baseball in the United States, Canada, and other international territories, which is produced by MLB Network and streams on Apple TV+.
 * NBC Sports re-entered MLB broadcasting with MLB Sunday Leadoff, a new exclusive package of Sunday afternoon games streamed on Peacock. The contract will initially be for two years.
 * TBS switched from late-season Sunday games to Tuesday-night games throughout the season.
 * MLB Network broadcasts various games throughout the season, including original MLB Network Showcase games, and simulcasts of games from local broadcasters.
 * The MLB Game of the Week Live on YouTube returned with fifteen games during the season.

For the postseason, ESPN networks held rights to the wild-card round; due to logistical concerns (especially with the fluctuating placements of teams in the standings during the final games of the regular season), the network employed remote production for the Padres/Mets and Mariners/Blue Jays series. The latter series employed a variant of the "enhanced world feed" model used in the 2020 season, with commentators and other selected staff on-site at Rogers Centre, but using video feeds from the Sportsnet production.

Fox Sports held rights to the National League Division Series, Championship Series, and the World Series for the 23rd consecutive season; while TBS held rights to the American League Division Series and Championship Series. Spanish-language broadcasts of all ALDS and ALCS games aired on MLB Network.

Local

 * Amazon Prime Video exclusively streamed 21 Yankees games in the Yankees home market (except for the final game in the package, which was simulcast on both Prime Video and YES Network due to Aaron Judge's home run record). These games formerly were allocated to WPIX (which retains a sub-licensed 28-game Mets package from SNY).
 * Kevin Brown became the new primary play-by-play voice for the Baltimore Orioles on MASN, replacing Scott Garceau.
 * Kevin Frandsen became the new color commentator for the Washington Nationals on MASN, replacing F. P. Santangelo.
 * Dallas Braden became the new primary color commentator for the Oakland Athletics on NBC Sports California, replacing Ray Fosse.
 * In Canada, Sportsnet—the main Canadian rightsholder of MLB, and regional broadcaster of the co-owned Toronto Blue Jays—gained the rights to produce local broadcasts of postseason games in the event that the Blue Jays participate (as opposed to previous seasons, where it was required to simulcast the U.S. telecasts), featuring its main broadcast team of Buck Martinez and Pat Tabler (Sportsnet's alternate play-by-play announcer, Dan Shulman, had commitments to ESPN Radio's postseason coverage. This became moot for future seasons after Shulman announced that he would step down from ESPN Radio's coverage after the 2022 season to focus more on roles at Sportsnet).
 * On June 1, 2022, NESN, the television home of the Boston Red Sox, launched NESN 360, an over-the-top subscription streaming platform that offers live streams of Red Sox games without a cable subscription.
 * On June 23, 2022, Bally Sports soft-launched Bally Sports+, an over-the-top subscription streaming platform that offers live streams and market-specific video-on-demand content from its individual regional networks. At that time, Bally was able to negotiate the streaming rights for only five of the MLB teams it holds local TV rights to Detroit, Kansas City, Miami, Milwaukee, and Tampa.

National

 * ESPN Radio aired its 25th season of national coverage, including Sunday Night Baseball, Saturday games, Opening Day, the Home Run Derby, All-Star Game, and the entire Major League Baseball postseason. In October 2022, Dan Shulman announced that he would step down from ESPN Radio's MLB coverage after the 2022 postseason, with Jon Sciambi succeeding him as lead broadcaster for postseason coverage in 2023.
 * TUDN Radio aired Spanish-language coverage of select regular season and postseason games, including the Home Run Derby, the All-Star Game, and the World Series.

Local

 * On September 28, 2021, Dodgers radio announcer Jaime Jarrín announced his plans to retire after the 2022 season, his 64th as part of the Dodgers' Spanish radio broadcast team. Jarrín, who turned 86 that December, only worked Dodgers home games in 2022.
 * On March 31, 2022, the New York Mets and Audacy announced that the team's games would be openly streamed on WCBS's Audacy app stream and the Mets website throughout the Mets' territory to make up for shortfalls in the team's radio network, which since 2020 has only consisted of WCBS and WPSL in Ft. Pierce, Florida, where its spring training site is based. Audacy will also produce a Spanish-language broadcast for WEPN, which will also be available through the Audacy app.
