Reggie Jackson: Mr. October

By 4Baseball Staff · November 5, 2026 · 10 min read

Reggie Jackson's career in phases, from Arizona State and the Oakland dynasty to the three-homer World Series game of 1977, with 563 home runs, 2,597 strikeouts and what the numbers can and cannot say.

Reggie Jackson hit 563 home runs, drove in 1,702 runs and struck out 2,597 times, and the last of those numbers is the one that tells you the most about him. He swung as hard as anyone of his generation, he missed more than any hitter in the history of the sport (through 2025, nobody has more career strikeouts in the historical record), and when he connected the baseball went a long way. On October 18, 1977, in the sixth game of the World Series, he connected three times in a row.

That game gave him the nickname by which most people know him, and the nickname is a little unfair to the rest of his career. He was a regular-season star for two decades and an American League Most Valuable Player in 1973, with the Oakland Athletics, before he ever put on a Yankees uniform. But the postseason is where baseball does its remembering, and Jackson's postseason record is exceptional: 18 home runs and 48 RBI in 77 games across 11 postseasons, with World Series rings on both coasts.

This article follows the career in phases, from his boyhood in Pennsylvania to his Hall of Fame election in 1993. It uses the historical record for every figure, and it is explicit about what that database cannot tell you, such as wins above replacement or the speed of his bat. For the players he competed against, see the profiles of Johnny Bench, Joe Morgan and Mike Schmidt.

Origins: Abington, Arizona State and the second pick of 1966

Reginald Martinez Jackson was born on May 18, 1946, in Abington, Pennsylvania, outside Philadelphia. He bats and throws left-handed and stood 6 feet tall and 195 pounds by the time he reached the major leagues, according to the historical biographical data. He went to Arizona State University on a football scholarship and ended up as a baseball player, and in the amateur draft of 1966 he was taken second overall by the Kansas City Athletics.

The first season was a false start. He debuted on June 9, 1967, with Kansas City and hit .178 in 35 games with one home run. The franchise moved to Oakland for the 1968 season, and Jackson became a full-time right fielder. His statistics that year show both halves of what he would be: 29 home runs, a .250 average and 171 strikeouts, the most in the American League. It is rare for a second-year player to lead the league in strikeouts, and it is just as rare for the team to keep playing him anyway. The Athletics did, and the patience was rewarded.

1969: 47 home runs and a sudden national figure

The 1969 season was Jackson's introduction to the public. Baseball had just come out of the "Year of the Pitcher," in which the mound had been so high and the strike zone so large that the American League as a whole hit about .230. In response the sport lowered the mound and shrank the zone for 1969, and offense recovered. Jackson went from 29 home runs to 47, third in the American League behind Harmon Killebrew (49) and Frank Howard (48), with 118 RBI and a .275 average. He was an All-Star for the first time.

The pace made it a story. For much of the first half he was on track to threaten Roger Maris's record of 61, and writers followed him from city to city. He faded in the second half, which is common for a young hitter chasing a record, and the next year's numbers dropped back: 23 home runs and a .237 average in 1970. The pattern would repeat across his career, with a bright year followed by a quiet one, and it is worth keeping in mind when you read the totals. Jackson was never a smooth, steady hitter. He was a streaky one.

By 1971 the Athletics had built a team around him. Jackson hit .277 with 32 home runs and 157 hits, and the club won the American League West for the first of what would be five consecutive division titles, from 1971 through 1975. The historical data shows Oakland teams that won with pitching, defense and a lineup that included Bert Campaneris, Joe Rudi, Sal Bando and Gene Tenace, and with an owner, Charlie Finley, whose management style was a constant subject of newspaper coverage.

The dynasty: three championships and an MVP

The Athletics won the World Series in 1972, 1973 and 1974. For anyone interested in the details of the three-year run, the sheet reads: 1972 (won), 1973 (won), 1974 (won). Jackson's role was different each year.

In 1972, he tore a hamstring sliding home in the ALCS against Detroit, a series Oakland won 3-2, and missed the World Series. The Athletics beat Cincinnati without him. In 1973 he had his best regular season: .293 with 158 hits, 32 home runs and 117 RBI, leading the league in both home runs and RBI, and he won the American League MVP award. In the World Series that fall, against the New York Mets, a series Oakland won 4-3, he was named World Series MVP. In 1974 he hit .289 with 29 home runs and 93 RBI, and the Athletics beat the Los Angeles Dodgers for a third straight title. In 1975 he led the league in home runs (36, tied with George Scott), though Oakland lost the ALCS to Boston.

It helps to read these numbers against the era. The designated hitter came to the American League in 1973, so a lineup could keep an extra slugger in the order in place of a weak-hitting pitcher, and the major leagues as a whole scored 4.21 runs per team-game that season. Against that background Jackson's 117 RBI stood ten clear of the runner-up, George Scott, with 107.

One year in Baltimore and the first free agent class

The end of the Oakland run came fast. In April 1976 Finley traded Jackson to the Baltimore Orioles, who gave up three players in return, because Finley knew that his stars could soon leave as free agents and he wanted to get something for them. Jackson played one season in Baltimore: 27 home runs, .277 average, 91 RBI. He declined to sign with the Orioles for 1977, and he became a free agent in the first re-entry draft. The background to that moment, the Messersmith decision and the end of the reserve clause, is in the free agency era article.

He signed with the New York Yankees for a five-year contract worth just under three million dollars, a figure that was breathtaking then and is a modest salary now. The deal made him the face of the arrival of the free-agent era. It also made him a target. There was friction with the Yankees' captain, Thurman Munson, and manager, Billy Martin, over a newcomer who had been billed as the star, and the 1977 season was among the most turbulent in the club's history, including a nationally televised dugout confrontation between Martin and Jackson at Fenway Park in June. Jackson hit .286 with 32 home runs and 110 RBI in the regular season, and the Yankees won the American League East and the pennant.

October 18, 1977: three swings, three home runs

The 1977 World Series pitted the Yankees against the Los Angeles Dodgers. The Yankees led the series three games to two when Game 6 was played at Yankee Stadium. Jackson had already hit a home run in Game 4 and another in Game 5. In Game 6, he walked in his first plate appearance, and then hit a home run in each of his next three at-bats, against three different Dodgers pitchers: Burt Hooton, Elias Sosa and Charlie Hough. Each came on the first pitch he swung at. The Yankees won the game and the Series, 4-2.

Only Babe Ruth had hit three home runs in a World Series game before, and he had done it twice. Jackson's five home runs in the Series set a record for a single Series. He won the World Series MVP award, as he had in 1973, and the Babe Ruth Award as the best performer of that postseason.

The "Mr. October" nickname is usually traced to Munson, who is said to have used it sarcastically earlier in that 1977 postseason, after Jackson had second-guessed manager Billy Martin. Whether or not that account is exactly right, the label stuck after the third homer. It is a mistake to read the nickname as a statistic, though. Jackson's postseason career batting line was 78 hits in 281 at-bats, a .278 average. That is good rather than historic. What made him Mr. October was the power, the 18 home runs, and the timing.

Yankee years: 1978 to 1981

The Yankees won the World Series again in 1978, beating the Dodgers once more, and Jackson was on the roster. His regular-season numbers in the four seasons from 1978 through 1981 were consistent: 27 home runs and 97 RBI in 1978, 29 and 89 in 1979 (.297), and 41 home runs, 111 RBI and a .300 average in 1980, a year in which he tied for the American League lead in home runs with Ben Oglivie. Mike Schmidt led the National League that year with 48. Jackson won a Silver Slugger Award for 1980, the first of two.

In 1981, a strike split the season in two, and Jackson hit .237 in 94 games. The Yankees reached the World Series again, and lost to the Dodgers 4-2. That was his last time on a team in the Series. He and the Yankees did not agree on a new contract after the year.

The Angels, 500 home runs and a return to Oakland

In 1982 Jackson signed with the California Angels. In his first year, he hit 39 home runs, tied with Gorman Thomas for the American League lead, drove in 101 runs and won his second Silver Slugger Award. It was his fourth league home run title or share of one, after 1973, 1975 and 1980. The Angels won the American League West in 1982, though they lost the ALCS to Milwaukee. He hit his 500th home run in 1984, joining a short list of players.

The numbers after that show a hitter in slow decline: 14 home runs in 1983 on a .194 average, 25 in 1984 on .223, 27 in 1985 on .252, and 18 in 1986 on .241. His last All-Star Game was in 1984, his 14th selection in the historical data. He finished where he began, with the Athletics, in 1987, hitting .220 with 15 home runs in 115 games. His final game was on October 4, 1987.

What the numbers say, and what they cannot

The number to look at first is on-base percentage. A .262 average looks ordinary, but Jackson walked 1,375 times, which lifted his OBP to .356, and his .490 slugging average was well above the league norm of his era. His OPS of .846 reflects a hitter who produced a lot of runs for a player who hit .262. That is the case for the Hall of Fame, and it is a case that traditional measures understate.

The strikeouts need the same careful reading. Jackson's total of 2,597 was the career record at the time he retired and, through 2025, remains ahead of Jim Thome (2,548) and Adam Dunn (2,379), according to the historical record. But strikeouts were less common in his time than they are now. In 1969 the average major-league team struck out 5.77 times a game, and in 1973 5.24, against more than eight per team-game in recent seasons. In his own era a hitter who whiffed 150 times a year was unusual. Today he would be unremarkable. The right way to see the record is that Jackson swung for power in a period when most hitters did not.

What the historical record cannot tell you matters as well. It carries no wins above replacement, so there is no number here for his total value including defense and baserunning. It has no Statcast data (bat speed, exit velocity, sprint speed), so any claim about how hard he hit the ball is anecdote. It records fielding only as putouts, assists and errors, which means his defense in right field, where he spent most of his career, cannot be judged well from it. His career began after the color line fell, so the partial Negro Leagues coverage in the database does not touch him, but it matters when you compare him with older sluggers.

The Hall of Fame and after baseball

Jackson was elected to the Hall of Fame in 1993, his first year on the ballot, with 396 votes of 423 cast, 318 being the number required. That was about 94 percent. His plaque shows a Yankees cap. Both the Yankees and the Athletics have retired a number in his honor.

After he retired, he stayed close to the sport. He worked for the Yankees as an advisor, and he remained a visible figure in postseason coverage. A candy bar was named for him in 1978. The cultural afterlife of the "Mr. October" phrase has been long, and has overshadowed some of the regular-season record, including the 1973 MVP award and four home run titles or shares of them.

Common questions

How many home runs did Reggie Jackson hit? 563 in the regular season, and 18 in the postseason. His career-high was 47 in 1969.

How many World Series did he win? Five of his teams won the Series (1972, 1973, 1974, 1977 and 1978), though an injury kept him out of the 1972 Series, so he played in four winning Series. He also lost one with the Yankees in 1981.

Did he hit three home runs on three pitches? He hit three home runs in three consecutive at-bats in Game 6 of the 1977 World Series, each on the first pitch he swung at, off three pitchers. The statement is sometimes shortened to "three swings, three home runs," which is a fair summary.

Where does he rank in career home runs? The historical record lists him with 563. The three leaders are Barry Bonds (762), Hank Aaron (755) and Babe Ruth (714), and several hitters have passed Jackson since he retired.

Was he the best postseason hitter ever? The numbers show a strong, not a unique, record. His average in October was .278. The case for him is the 18 home runs and the 1977 World Series.
