The Best Cincinnati Reds Seasons and Every October Run
Cincinnati's best regular seasons ranked by winning percentage, plus all 23 postseason series the Reds have played, from the 1919 title to the 2025 wild-card exit, grouped by era.
The Cincinnati Reds have won five World Series, and two of them came in consecutive years, 1975 and 1976, with a third in 1990. The record book gives the club ten pennants, ten division titles and three wild-card berths through the 2025 season, but the shape of the franchise's October history is lumpy: long dry spells, then a burst of excellence so complete that it still defines the team's identity. The Big Red Machine of the 1970s is the centre of that story, though it is not the whole of it.
This article walks through the club's best regular seasons by winning percentage and then through every postseason series the Reds have played, in order, with the results from the historical record. The point is to see the pattern: what a great Reds team looked like in each era, how often a great regular season turned into a title, and how many of the near-misses came from the same few opponents. Where a number does not appear, it is because the database does not carry it, and the article says so instead of guessing.
If you want the whole franchise story, from the Red Stockings of 1882 to the present, the history of the Cincinnati Reds covers every era, and the best players in Reds history covers the people. This piece sticks to seasons and series.
The six best seasons by winning percentage
Among Reds seasons of 100 or more games, six stand clear of the rest by winning percentage. Winning percentage is the right way to rank them, because the schedule changed: 140 games in 1919, 154 in 1939 and 1940, 162 from 1962 onward. Raw win totals would unfairly favour the later years.
| Season | Record | Win pct | Finish | Result |
|---|---|---|---|---|
| 1919 | 96-44 | .686 | First | World Series champions |
| 1975 | 108-54 | .667 | First | World Series champions |
| 1940 | 100-53 | .654 | First | World Series champions |
| 1939 | 97-57 | .630 | First | Pennant, lost World Series |
| 1970 | 102-60 | .630 | First | Pennant, lost World Series |
| 1976 | 102-60 | .630 | First | World Series champions |
Two things stand out. First, the best-percentage season is not the one with the most wins. The 1919 club won 96 games in a 140-game schedule, which beats the 1975 team's percentage even though the 1975 team won 12 more games. Second, every one of these six teams finished first and played in the World Series, and four of the six won it. A great regular season in Cincinnati has usually meant a deep October, with the 1939 and 1970 clubs as the exceptions that prove how hard a seven-game series is to win.
The worst seasons give the other side of the ledger. In the database's list of the club's weakest years, 1934 (52-99), 1937 (56-98), 1901 (52-87), 1982 (61-101) and 1931 (58-96) all finish at or near the bottom of the league. The Reds' history is a series of peaks separated by real valleys, and the 1982 collapse came only six years after the 1976 title.
1882 to 1919: a pennant in the American Association and a disputed title
The franchise began in 1882 as the Cincinnati Red Stockings of the American Association, and the club won that league's pennant in its first season. There was no World Series yet in any form that the historical record shows for that year, so the 1882 pennant sits on the ledger without a series attached. The club moved to the National League in 1890 and then spent nearly three decades without a pennant.
The next trophy came in 1919, and it is the strangest title in the club's history. The Reds went 96-44, finished first with the best winning percentage on the list above, and beat the Chicago White Sox five games to three in a best-of-nine World Series. That format is worth noting: the World Series ran as best-of-nine in 1919, 1920 and 1921 before returning permanently to best-of-seven.
The trouble is that the White Sox were not playing straight. Eight Chicago players were later banned for life by the first commissioner, Kenesaw Mountain Landis, after allegations that they had agreed to throw the Series for gamblers; a jury acquitted them at trial, but Landis banned them anyway. That history, the Black Sox scandal, has hung over the 1919 result ever since. It is fair to say two things at once. The Reds were a very good team, with the best percentage among their top seasons to prove it, and the Series they won was tainted by what the other dugout was doing. The history of the World Series covers the nine-game format and the scandal in more detail.
1939 to 1961: two pennants, one title and a long wait
Bill McKechnie managed the club for nine seasons, from 1938 to 1946, and went 744-631 in 1,386 games. Under him the Reds won consecutive pennants in 1939 and 1940. The league's Most Valuable Player award went to a Red three years running: catcher Ernie Lombardi in 1938, pitcher Bucky Walters in 1939 and first baseman Frank McCormick in 1940.
The 1939 team went 97-57 and met the Yankees in the World Series. The Yankees swept it, 4-0. The 1940 team went 100-53 and met Detroit in the Series, which went the full seven games, and the Reds won it 4-3. It was the club's second title, and it came 21 years after the first.
Then came a long wait of a different kind. The Reds did not win another pennant until 1961, under Fred Hutchinson, when they went 93-61 and won the pennant. Frank Robinson won the MVP award that year, one of twelve MVP awards won by Reds players. The World Series was a repeat of 1939 in one respect: the Yankees were waiting, and they won it four games to one. The Reds would not return to the World Series for nine years, and when they did, they would arrive as something else entirely.
1970 to 1972: the Machine arrives and loses twice
Sparky Anderson took over in 1970 and held the job through 1978, going 863-586 in 1,450 games, the most wins of any manager in club history. The 1970 team went 102-60 and won the National League West, which is how the division format first appears in Cincinnati's record. They swept Pittsburgh in the National League Championship Series, 3-0, and met Baltimore in the World Series, where the Orioles won four games to one.
The 1970 season was also the first year at Riverfront Stadium, which the historical park list shows opening partway through the year (the season is split between Crosley Field and Riverfront). The club's best attendance up to that point, 1,803,568, came that year. The new park had an artificial surface, and it became the home of the most successful stretch in the club's history.
Two years later the Reds were back. The 1972 club went 95-59 in a strike-shortened 154-game schedule, beat Pittsburgh three games to two in the NLCS, and met Oakland in the World Series. That Series went the full seven games, and Oakland won it, 4-3. The Reds had lost the 1970 Series in five and the 1972 Series in seven, and the 1973 NLCS was still to come.
The 1973 team went 99-63 and won the division, and then lost the NLCS to the New York Mets, 3-2. The series is best remembered for a fight between Pete Rose and the Mets shortstop Bud Harrelson at second base, which is well documented, but the result is simple: a 99-win team lost a five-game series. Three October losses in four years is the context for what came next. The Machine had earned its reputation for winning the regular season, but October had not yet followed.
1975 and 1976: the best team in franchise history
The 1975 Reds went 108-54, the most wins in club history, and scored 840 runs against 586 allowed, a run differential of 254. They swept Pittsburgh in the NLCS, 3-0, and then met Boston in a World Series that many fans still rank among the best ever played. It went the full seven games, and Cincinnati won it, 4-3. Game 6, which Boston won on a home run by Carlton Fisk in the twelfth inning, is one of the most replayed moments in baseball, and Game 7 went to the Reds.
The 1976 team was nearly as good: 102-60, with 857 runs scored, the most of any Reds team in this period. The postseason was perfect. The Reds swept Philadelphia in the NLCS, 3-0, and then swept the Yankees in the World Series, 4-0. That is seven wins in seven games, and it is why the 1976 team is often named as the high point of the franchise. The club also set its season attendance record that year, drawing 2,629,708 fans to Riverfront Stadium.
The two MVP awards in this period tell the same story. Johnny Bench won in 1970 and 1972, Pete Rose in 1973, Joe Morgan in 1975 and 1976, and George Foster in 1977. Six MVP awards in eight seasons for a single lineup is extraordinary, and the club's all-time leaders show how deep the lineup ran: Bench holds the club record for home runs with 389 and for runs batted in with 1,376, Rose for hits with 3,358, and Morgan stole 406 bases in his eight seasons with the club. Pete Rose, Johnny Bench, Tony Perez and Joe Morgan all spent most of their primes in this lineup, and the all-time greats article compares them position by position.
1977 to 1989: the Machine fades, and one strike-year injustice
The 1977 team won 88 games and finished second in the West, and the 1978 team won 92 and finished second again. The Reds won the division one more time with the original core, in 1979, going 90-71. They met Pittsburgh in the NLCS and were swept, 3-0, by a Pirates team that went on to win the World Series. It was the end of an era; the 1979 loss was the last postseason series for the Machine.
The 1980s were thin. The club finished third in 1980 and then went 66-42 in the strike-split 1981 season. By the database's record that gave the Reds the best overall record in the National League, and it still did not earn a postseason berth, because the split-season format sent division winners from each half to the playoffs and the Reds had won neither half. It is one of the cleaner examples of how a format can overrule a record. In 1982 the Reds fell to 61-101, one of the weakest seasons in the club's record.
Pete Rose came back as player-manager in 1984 and managed the club through 1989, going 412-373 in 786 games. The team was competitive but never won the division in those years. The franchise history tells the rest of that story, including how the Rose era ended.
1990: wire-to-wire and a sweep of Oakland
The surprise of 1990 was that it happened at all. Lou Piniella's club went 91-71, a modest record by the standards of the 1970s, and led the National League West from the first day of the season to the last. The Reds then beat Pittsburgh in the NLCS, 4-2, and they met Oakland in the World Series.
Oakland, the defending champion, was a heavy favourite. The Reds swept the Series, 4-0. Jose Rijo, whose 1,251 strikeouts in a Reds uniform are tied for fourth in club history, was the World Series most valuable player, and a bullpen known as the Nasty Boys held the lead in the late innings. This is the fifth and most recent Reds championship, and it came in a year when the regular-season record did not predict the result.
The 1990 team is the only one of the five champions to win fewer than 95 games in the regular season, which is a reminder that October rewards a hot team as much as a deep one. Barry Larkin, the club's Hall of Fame shortstop, was on that roster, and he went on to win the 1995 MVP award, which gives the transition between the 1990 and 1995 teams a human thread.
1995 to 2013: back to the postseason, and back out again
The Reds returned to the playoffs in 1995, when a new three-division format created the National League Central. The club went 85-59 in the 144-game season shortened by the strike, won the division, and swept the Los Angeles Dodgers in the first National League Division Series, 3-0. That is the last time the Reds have won a postseason series. In the NLCS, Atlanta swept them, 4-0.
Cincinnati missed the playoffs in 1999 despite going 96-67. The club finished second in the Central, tied for the wild card and lost a one-game playoff to the Mets. It was a painful way to miss October, but it is not a postseason series and does not appear in the series list.
The next two playoff appearances were division titles under Dusty Baker. In 2010, the Reds went 91-71 and won the Central, with Joey Votto winning the MVP award, but Philadelphia swept them in the Division Series, 3-0; Roy Halladay threw a no-hitter in Game 1. In 2012 the Reds went 97-65, their most wins since 1976, and won the first two games of the Division Series against San Francisco. The Giants won the next three, and the series ended 3-2 in their favour. Anyone who wants to know where the Reds' modern October reputation comes from can start there.
In 2013 the Reds finished third in the Central at 90-72 and won a wild-card berth, then lost the one-game wild-card playoff to Pittsburgh. The Pirates were an opponent the Reds had beaten in four postseason series in the 1970s and 1990. The Pirates' own record of the same postseasons shows the other side of that history.
The scorecard: 23 series, 11 won, 12 lost
Counting every round in the database, the Reds have played 23 postseason series. They have won 11 and lost 12. Broken down by round, the numbers are more striking:
| Round | Series | Won | Lost |
|---|---|---|---|
| World Series | 9 | 5 | 4 |
| League Championship Series | 8 | 5 | 3 |
| Division Series | 3 | 1 | 2 |
| Wild Card | 3 | 0 | 3 |
The Reds have won more than half of their World Series. The wild-card rounds are another matter: three series, three losses, and not one postseason game won across them. The 2020 pandemic-era best-of-three against Atlanta ended 0-2, and the 2025 best-of-three against the Dodgers ended 0-2 too.
The pattern that matters most is the opposition. Of the 23 series, six were against Pittsburgh. The Reds won four of them, in 1970, 1972, 1975 and 1990, and lost two, in 1979 and in the 2013 wild-card game. That is a rivalry across eras that shows up in the postseason ledger.
What the near-misses have in common
Look across the 12 losing series and a few patterns appear. Four were in the World Series (1939, 1961, 1970 and 1972), and three of those four were against the Yankees or the Orioles. The 1972 loss to Oakland was the closest, a seven-game decision decided by one game.
The League Championship Series losses came in 1973, 1979 and 1995. The 1973 loss is the starkest: the Reds won 99 games and lost a five-game series to a New York team that finished the regular season barely above .500. Short series reward a hot week more than a good year, which is also why the 1990 Reds could win with 91 wins and the 1973 Reds could lose with 99.
The Division Series and wild-card losses, from 2010 on, tell a different story. These series are shorter, five games or fewer, so a single bad inning can decide them. A best-of-three wild-card round leaves almost no room for a rotation to be stretched. The franchise has lost all three of its wild-card series, and the fairest reading is that the format favours no team in particular, not that the Reds are uniquely unlucky. What can be said is that the club's last series win came in 1995, and that the three decades since have produced five playoff appearances and no series victory.
