Historical MLB playoff brackets: choose the right year and format
Atlanta won the 2021 World Series, Washington won in 2019, Boston won in 2018 and St. Louis won in 2011. This guide preserves the complete matchup results for those four seasons, rather than applying today's bracket to an older playoff field.
| Year | Playoff teams | Opening stage | World Series champion | Final series result |
|---|---|---|---|---|
| 2021 | 10 | Two single Wild Card games | Atlanta Braves | Beat Houston 4–2 |
| 2019 | 10 | Two single Wild Card games | Washington Nationals | Beat Houston 4–3 |
| 2018 | 10 | Two single Wild Card games | Boston Red Sox | Beat Los Angeles 4–1 |
| 2011 | 8 | Division Series | St. Louis Cardinals | Beat Texas 4–3 |
In 2021, 2019 and 2018, each league qualified three division winners and two Wild Card teams. The two Wild Cards played one winner-take-all game, with the survivor joining the three division winners in the Division Series. A Wild Card final such as “Boston 6, New York 2” is the score of that single game.
In 2011, each league qualified three division winners and one Wild Card. All eight entrants went directly into the Division Series. St. Louis did qualify as a Wild Card team, but there was no separate Wild Card game for it to win.
All four seasons used best-of-five Division Series and best-of-seven League Championship Series and World Series. MLB's Wild Card history explains the transition to the two-Wild-Card format in 2012 and the return to it in 2021 after the exceptional 2020 postseason.
Series results below show the winner's victories first. Individual World Series game tables instead show runs. Keeping those two measurements separate makes each archived bracket easier to read. For a longer view of the changes between eras, see the MLB playoff format history.
2021 MLB playoff bracket: Braves beat Astros in six
The Atlanta Braves won the 2021 World Series four games to two over Houston. The postseason began with the AL Wild Card Game on October 5 and ended with Atlanta's championship-clinching win on November 2.
The ten teams and every 2021 round result
The AL division winners were Tampa Bay, Houston and the Chicago White Sox; Boston and the New York Yankees qualified as Wild Cards. The NL division winners were San Francisco, Milwaukee and Atlanta; Los Angeles and St. Louis were the Wild Cards.
| Round | Winner | Opponent | Result |
|---|---|---|---|
| AL Wild Card game | Boston Red Sox | New York Yankees | 6–2 game score |
| NL Wild Card game | Los Angeles Dodgers | St. Louis Cardinals | 3–1 game score |
| ALDS | Boston Red Sox | Tampa Bay Rays | 3–1 series |
| ALDS | Houston Astros | Chicago White Sox | 3–1 series |
| NLDS | Los Angeles Dodgers | San Francisco Giants | 3–2 series |
| NLDS | Atlanta Braves | Milwaukee Brewers | 3–1 series |
| ALCS | Houston Astros | Boston Red Sox | 4–2 series |
| NLCS | Atlanta Braves | Los Angeles Dodgers | 4–2 series |
| World Series | Atlanta Braves | Houston Astros | 4–2 series |
The Wild Card survivors entered different branches. Boston next played Tampa Bay, while Los Angeles next played San Francisco. A Wild Card team's win did not give it a choice of opponent, and it did not turn the opening game into a best-of-three series.
The Dodgers–Giants matchup was the only Division Series to reach Game 5. Both League Championship Series finished in six games. These results account for every advancing team in the ten-team field, including the two clubs eliminated before the Division Series began.
Atlanta’s route and World Series game scores
Atlanta qualified as a division winner and began against Milwaukee. It then beat Los Angeles for the NL pennant before defeating Houston. Its completed postseason record was eleven wins and five losses: three victories in the Division Series, four in the NLCS and four in the World Series.
| World Series game | Date in 2021 | Final |
|---|---|---|
| 1 | October 26 | Atlanta 6, Houston 2 |
| 2 | October 27 | Houston 7, Atlanta 2 |
| 3 | October 29 | Atlanta 2, Houston 0 |
| 4 | October 30 | Atlanta 3, Houston 2 |
| 5 | October 31 | Houston 9, Atlanta 5 |
| 6 | November 2 | Atlanta 7, Houston 0 |
Atlanta took a three-games-to-one lead, lost Game 5 at home, then clinched in Houston. The 7–0 finale is the championship game score; the 4–2 beside Atlanta in the final bracket is the series score. MLB's completed schedule preserves the dates, while its Game 5 report confirms Houston's 9–5 survival win.
2019 MLB playoff bracket: Nationals won a seven-game World Series
The Washington Nationals won the 2019 World Series four games to three over Houston. Their postseason began with a Wild Card game on October 1 and ended with a Game 7 victory on October 30.
Every 2019 matchup from the Wild Card games onward
| Round | Winner | Opponent | Result |
|---|---|---|---|
| AL Wild Card game | Tampa Bay Rays | Oakland Athletics | 5–1 game score |
| NL Wild Card game | Washington Nationals | Milwaukee Brewers | 4–3 game score |
| ALDS | Houston Astros | Tampa Bay Rays | 3–2 series |
| ALDS | New York Yankees | Minnesota Twins | 3–0 series |
| NLDS | Washington Nationals | Los Angeles Dodgers | 3–2 series |
| NLDS | St. Louis Cardinals | Atlanta Braves | 3–2 series |
| ALCS | Houston Astros | New York Yankees | 4–2 series |
| NLCS | Washington Nationals | St. Louis Cardinals | 4–0 series |
| World Series | Washington Nationals | Houston Astros | 4–3 series |
Houston, New York and Minnesota were the AL division winners; Tampa Bay and Oakland were the Wild Cards. Los Angeles, Atlanta and St. Louis were the NL division winners; Washington and Milwaukee were the Wild Cards. The table accounts for all ten entrants.
Three Division Series went to a fifth game. Washington survived its matchup against Los Angeles, then swept St. Louis for the pennant. Houston beat Tampa Bay in five and New York in six before meeting Washington. Those completed paths are preserved in MLB's 2019 postseason archive.
Washington’s road-only World Series victories
| Game | Date in 2019 | City | Final |
|---|---|---|---|
| 1 | October 22 | Houston | Washington 5, Houston 4 |
| 2 | October 23 | Houston | Washington 12, Houston 3 |
| 3 | October 25 | Washington | Houston 4, Washington 1 |
| 4 | October 26 | Washington | Houston 8, Washington 1 |
| 5 | October 27 | Washington | Houston 7, Washington 1 |
| 6 | October 29 | Houston | Washington 7, Houston 2 |
| 7 | October 30 | Houston | Washington 6, Houston 2 |
The road team won every game. Washington won Games 1 and 2 in Houston, lost all three home games, then won Games 6 and 7 back in Houston. MLB's World Series facts account confirms the championship without a home victory.
Washington's total postseason record was twelve wins and five losses. Its opening Wild Card victory counted as one win, followed by three in the Division Series, four in the NLCS and four in the World Series. A modern bracket requiring two opening-round wins would produce the wrong total for this season.
When filling in an archive, label the Wild Card game separately and keep Washington on its original branch. The final champion's line runs through Milwaukee, Los Angeles, St. Louis and Houston. The road-only pattern belongs specifically to the World Series, rather than describing every game Washington played that postseason.
2018 MLB playoff bracket: Red Sox won the title in five games
The Boston Red Sox won the 2018 World Series four games to one against Los Angeles. Boston entered as an AL division winner, beat New York in the Division Series, then Houston in the ALCS before taking the championship.
The complete 2018 series results
| Round | Winner | Opponent | Result |
|---|---|---|---|
| AL Wild Card game | New York Yankees | Oakland Athletics | 7–2 game score |
| NL Wild Card game | Colorado Rockies | Chicago Cubs | 2–1 game score; 13 innings |
| ALDS | Boston Red Sox | New York Yankees | 3–1 series |
| ALDS | Houston Astros | Cleveland Indians | 3–0 series |
| NLDS | Milwaukee Brewers | Colorado Rockies | 3–0 series |
| NLDS | Los Angeles Dodgers | Atlanta Braves | 3–1 series |
| ALCS | Boston Red Sox | Houston Astros | 4–1 series |
| NLCS | Los Angeles Dodgers | Milwaukee Brewers | 4–3 series |
| World Series | Boston Red Sox | Los Angeles Dodgers | 4–1 series |
The ten-team field consisted of Boston, Cleveland and Houston as AL division winners, with New York and Oakland as Wild Cards. Milwaukee, Los Angeles and Atlanta won the NL divisions; Colorado and Chicago were the NL Wild Cards. Cleveland's historical name in this season was Indians.
Before the playoffs began, two October 1 tiebreaker games settled NL division titles. Milwaukee beat Chicago 3–1, and Los Angeles beat Colorado 5–2. Those were regular-season Game 163s, rather than additional postseason rounds. Colorado then beat Chicago in the actual NL Wild Card game on October 2. MLB's tiebreaker account distinguishes the two stages.
| World Series game | Date in 2018 | Final |
|---|---|---|
| 1 | October 23 | Boston 8, Los Angeles 4 |
| 2 | October 24 | Boston 4, Los Angeles 2 |
| 3 | October 26 | Los Angeles 3, Boston 2; 18 innings |
| 4 | October 27 | Boston 9, Los Angeles 6 |
| 5 | October 28 | Boston 5, Los Angeles 1 |
Game 3 was Los Angeles' only World Series victory and lasted eighteen innings. The official game recap confirms the 3–2 final. Boston won the next two games to finish the series rather than allowing that extra-inning loss to become another Dodgers victory on the bracket.
Boston finished eleven wins and three losses across its three playoff series. That total excludes the Wild Card stage because the Red Sox did not play in it. The single-game Wild Card winners had one additional game on their routes, but neither reached the World Series.
2011 MLB playoff bracket: Cardinals won without a Wild Card game
The St. Louis Cardinals won the 2011 World Series four games to three against Texas. St. Louis qualified as the NL Wild Card, but went straight into the Division Series under that season's eight-team format.
All eight teams and every 2011 series
New York, Detroit and Texas won the AL divisions, with Tampa Bay taking the league's only Wild Card. Philadelphia, Milwaukee and Arizona won the NL divisions, with St. Louis taking the sole NL Wild Card. The four opening series began the postseason without a preceding elimination round.
| Round | Winner | Opponent | Series result |
|---|---|---|---|
| ALDS | Detroit Tigers | New York Yankees | 3–2 |
| ALDS | Texas Rangers | Tampa Bay Rays | 3–1 |
| NLDS | Milwaukee Brewers | Arizona Diamondbacks | 3–2 |
| NLDS | St. Louis Cardinals | Philadelphia Phillies | 3–2 |
| ALCS | Texas Rangers | Detroit Tigers | 4–2 |
| NLCS | St. Louis Cardinals | Milwaukee Brewers | 4–2 |
| World Series | St. Louis Cardinals | Texas Rangers | 4–3 |
St. Louis needed a fifth game to beat Philadelphia, then six games to beat Milwaukee. Texas beat Tampa Bay in four and Detroit in six. The final matchup therefore joined the AL West division winner and the NL Wild Card.
An old bracket's opening pairings should be preserved rather than rebuilt from today's rules. The pre-2012 system included a restriction against same-division opponents meeting in the Division Series, as explained in MLB's Division Series history. That is another reason a modern twelve-team template cannot reconstruct 2011 automatically.
World Series Games 6 and 7 completed the comeback
| Game | Date in 2011 | Final |
|---|---|---|
| 1 | October 19 | St. Louis 3, Texas 2 |
| 2 | October 20 | Texas 2, St. Louis 1 |
| 3 | October 22 | St. Louis 16, Texas 7 |
| 4 | October 23 | Texas 4, St. Louis 0 |
| 5 | October 24 | Texas 4, St. Louis 2 |
| 6 | October 27 | St. Louis 10, Texas 9; 11 innings |
| 7 | October 28 | St. Louis 6, Texas 2 |
Texas led three games to two before the last two games in St. Louis. David Freese's eleventh-inning home run ended Game 6, tying the series. It was a survival win rather than the championship clincher. The dated official Game 6 highlights preserve that distinction.
The next night's 6–2 win completed the Cardinals' comeback and the season's final bracket. St. Louis finished eleven wins and seven losses across its three playoff series. No Wild Card game should be added to that record; the extra opening stage did not arrive until the following year.
Compare these archived brackets without mixing their formats
These four champions reached the same finish line through different opening rounds. A season's final bracket tells you who advanced, but its format explains how many wins were needed to get there. Start with the year, then read the bracket from left to right. That keeps a single Wild Card game from being mistaken for a series and prevents a current twelve-team template from changing an older tournament.
| Year and champion | How the champion qualified | First postseason round played | Champion's postseason record |
|---|---|---|---|
| 2021 Atlanta Braves | NL East division winner | Division Series | 11-5 |
| 2019 Washington Nationals | NL Wild Card | Single Wild Card game | 12-5 |
| 2018 Boston Red Sox | AL East division winner | Division Series | 11-3 |
| 2011 St. Louis Cardinals | NL Wild Card | Division Series | 11-7 |
Washington needed twelve postseason wins because its 2019 route included the Wild Card game. St. Louis needed eleven in 2011 because that year's Wild Card berth led directly to the Division Series. Neither total means a champion skipped a required round. Boston and Atlanta also needed eleven wins, split between a best-of-five Division Series and two best-of-seven rounds. The loss column shows how close each champion came to elimination along that route.
When saving or printing an old bracket, choose a template that matches the season's number of teams and opening round. Add the final series record beside each advancing club, and keep individual game scores in a separate list. For 2018, leave the two regular-season division tiebreakers outside the postseason bracket. For 2019, mark the World Series game locations if you want to see why its seven road victories stand out.
For another completed season, the 2023 playoff bracket results and 2025 playoff bracket results show the later twelve-team format with best-of-three Wild Card Series. The World Series winners by year guide helps you find a champion beyond the four seasons covered here. Keep that year's tournament structure beside the result, and the path from the first round to the trophy becomes much easier to follow.
