Steve Carlton: Lefty and the 1972 Phillies Season
Steve Carlton won 27 games for a Phillies team that won only 59 in 1972, and his career ran to 329 wins, 4,136 strikeouts and four Cy Young Awards. A career profile built on the historical numbers.
In 1972 the Philadelphia Phillies won 59 games and lost 97, finishing sixth in the National League East. Their left-handed ace, Steve Carlton, won 27 of those 59 and lost 10. Put another way, every other pitcher on the staff combined to win 32 and lose 87. He led the league in wins, earned run average and strikeouts, and no other season in his career shows more clearly what one pitcher can do for a club that is otherwise losing.
That year is the center of his story, but it is only one chapter of a career that lasted from 1965 to 1988. Carlton finished with 329 wins, a 3.22 earned run average, 254 complete games and 4,136 strikeouts, the fourth highest total in the historical record through the 2025 season. This profile follows the career in phases: the young Cardinal, the trade and the 1972 season, the long peak, the decline and the Hall of Fame, and it uses the historical numbers for every figure. It also says where those numbers stop being useful.
A Florida left-hander in St. Louis
Carlton was born on December 22, 1944, in Miami, Florida, and the historical record lists him as a left-handed pitcher who also batted left-handed, listed at 6 feet 4 inches and 210 pounds. Its college table connects him to a Florida junior college. He debuted on April 12, 1965, with the St. Louis Cardinals, at 20 years old, and pitched 25 innings that season with a 2.52 earned run average and 21 strikeouts.
His first full seasons in the National League were solid and unspectacular. In 1967 he went 14-9 with a 2.98 earned run average and 168 strikeouts in 193 innings, and in 1968 he went 13-11 with a 2.99 earned run average in 231.2 innings. The Cardinals won the National League pennant both years, and according to the historical data he was on their roster for the 1967 World Series win and the 1968 loss. Those teams were built on pitching, and Carlton was one of the younger arms behind a staff that the 1968 season made famous.
The year 1969 gave him a first look at what was coming. He went 17-11 with a 2.17 earned run average and 210 strikeouts in 236.1 innings, and on September 15 of that season he struck out 19 Mets in a game and still lost it. The next season brought the other kind of year: a 10-19 record with a 3.73 earned run average. A pitcher's win-loss record is a team record as much as a personal one, and 1970 is the first of several seasons in Carlton's table where the earned run average and the record seem to be telling different stories.
He bounced back in 1971 with a 20-9 record and a 3.56 earned run average, and was named to the All-Star team. The historical record lists ten All-Star selections for him, beginning in 1968, and 1971 was the third.
The trade and the 1972 season
Before 1972 Carlton had a contract dispute with the Cardinals, and in February the club traded him to the Phillies for Rick Wise, a swap remembered as one of the best-known trades of its era. The Phillies got by far the better of it.
The numbers speak for themselves:
| 1972 Carlton | Figure |
|---|---|
| Record | 27-10 |
| Earned run average | 1.97 |
| Innings | 346.3 |
| Strikeouts | 310 |
| Games | 41 |
He led the National League in wins, earned run average and strikeouts, which is the pitching Triple Crown, and he won the first of his four Cy Young Awards. The historical data also shows 30 complete games, the most in the majors that year, ahead of Gaylord Perry's 29. His 27 wins were three more than the next highest total in baseball, 24 each by Perry and Wilbur Wood. Nolan Ryan led the majors in strikeouts with 329 in the American League, so Carlton's 310 were the National League's best by a wide margin and second in baseball.
The context matters. In 1972 major-league teams averaged 3.69 runs per game, a low-scoring period, so a 1.97 earned run average was excellent but not out of reach for a few pitchers. What was unusual was the combination of the workload (346.3 innings), the strikeouts and the wins on a team that lost 97 games. A pitcher cannot control how many runs his team scores, and the Phillies' 59 wins are a ceiling on what he could win. That he won 27 of them, 45.8 percent of the club's total, is the reason the season is part of the sport's lore.
What the win total hides and shows
It is tempting to use the 27-10 record as a complete summary of the year, and it is the wrong tool. Wins depend on run support and on the bullpen, so a 27-win season on a 59-win team does not mean he pitched twice as well as someone with 14 wins on a good club. Earned run average and innings pitched say more, and by those measures the 1972 season is great on its own terms.
Carlton's own career shows how much the record can drift. In 1973 he went 13-20 with a 3.90 earned run average, the worst year of his prime, in which he pitched 293.1 innings and struck out 223. A pitcher who goes 27-10 and then 13-20 in successive seasons is a standard example of why baseball analysts moved away from wins as a measure. The difference between the two seasons is real, since 3.90 is not 1.97, but a 14-win swing is larger than the pitching alone would explain.
The sensible way to read the 1972 season is as the year Carlton became a different pitcher. He had been good for years, and he was suddenly dominant for a decade. The historical record can tell you what happened; it cannot tell you why, and anyone who offers a single cause is guessing.
The long peak with the Phillies
From 1972 through 1982, Carlton built a case that stands next to any left-hander of his generation. He won 20 or more games in six seasons, 1971, 1972, 1976, 1977, 1980 and 1982, and a selection of his years is in the table below.
| Season | Record | ERA | Innings | Strikeouts |
|---|---|---|---|---|
| 1972 | 27-10 | 1.97 | 346.3 | 310 |
| 1974 | 16-13 | 3.22 | 291.0 | 240 |
| 1976 | 20-7 | 3.13 | 252.7 | 195 |
| 1977 | 23-10 | 2.64 | 283.0 | 198 |
| 1980 | 24-9 | 2.34 | 304.0 | 286 |
| 1981 | 13-4 | 2.42 | 190.0 | 179 |
| 1982 | 23-11 | 3.10 | 295.7 | 286 |
In addition to 1972, he won the Cy Young Award in 1977, 1980 and 1982, for a total of four, which was more than any pitcher had won at that point. In 1977 he went 23-10 with a 2.64 earned run average. In 1980 he went 24-9 with a 2.34 earned run average and 286 strikeouts, led the National League in wins with 24 and was part of the first World Series title in Phillies history, as the historical data lists the 1980 club among his World Series teams. In 1982 he won 23 and struck out 286 again.
The shortened 1981 season was strike-affected, and he was 13-4 with a 2.42 earned run average in 190 innings. That year he also won a Gold Glove, an award voted on by managers and coaches that the box score cannot verify, but one that shows he was a sound fielder as well as a strikeout pitcher.
He was also famously defined by his slider, a pitch that broke away from left-handed hitters, and by his reputation for careful preparation and conditioning. Those descriptions are part of baseball's common record, not of the historical record, so they are best treated as well-documented reputation, not as measurements. In his later years with the club he also stopped speaking with reporters, a decision that belongs to the story of his public image more than to his numbers.
The postseason record
Carlton pitched in eight postseasons, with a career postseason record of 6-6 and a 3.26 earned run average over 99.3 innings (99 and a third), 14 starts and 84 strikeouts in the historical data. That is a modest line next to his regular-season record, and a small sample, since it covers fewer than 100 innings spread over eight postseasons.
The historical data lists five World Series teams that had him on the regular-season roster: the 1967 Cardinals (champions), the 1968 Cardinals (lost), the 1980 Phillies (champions), the 1983 Phillies (lost) and the 1987 Twins (champions). It does not say whether he pitched in each series, so a reader who wants his World Series starts should look at the individual game logs. The point for a fan is that his career had a late echo: he finished with Minnesota on a championship club, even if his own season was poor.
To see how those postseasons were organised, the guide to how the MLB postseason works explains the formats, from the one-round World Series era to the division-based October of today.
Decline and the final seasons
The end came quickly. He went 15-16 in 1983 with a 3.11 earned run average and 275 strikeouts, and 13-7 with a 3.58 earned run average in 1984. In 1985 he made 16 appearances, went 1-8 with a 3.33 earned run average in 92 innings and struck out only 48. His workload had dropped by two-thirds from a year earlier, and the strikeout rate was far below the 1980 level.
Then came the wandering. In 1986 he pitched for three teams, the Phillies, Giants and White Sox, going 9-14 with a 5.10 earned run average. In 1987 he split the season between Cleveland and Minnesota, going 6-14 with a 5.74 earned run average. His final game came on April 23, 1988, in his last season, with a 16.76 earned run average over 9 2/3 innings in four games.
A career can be judged by its peak or by its length, and Carlton's has both. The final three years were poor, as they usually are for pitchers who stay too long, but they did not erase the 1972 to 1984 stretch, which accounts for most of his strikeouts, wins and awards.
The career at a glance and in company
The full historical line reads: 329 wins and 244 losses, 3.22 earned run average, 741 games, 709 starts, 254 complete games, 55 shutouts, 5,217 1/3 innings, 4,672 hits allowed, 414 home runs allowed, 1,833 walks and 4,136 strikeouts, with a WHIP of 1.25. The Hall of Fame voting reflects that: in 1994, his first year on the Baseball Writers' ballot, he received 436 votes when 342 were needed, which is about 95.6 percent.
He ranks behind only three pitchers on the all-time strikeout list: Nolan Ryan with 5,714, Randy Johnson with 4,875 and Roger Clemens with 4,672. His contemporaries include Tom Seaver, whose 3,640 strikeouts rank sixth, and Juan Marichal, who was a star at the beginning of Carlton's career. The batting side of the game offers a parallel in Johnny Bench, whose Reds were one of the dominant National League teams of the 1970s.
Carlton also batted, in an era before the designated hitter in his league, and the historical data shows a .201 average with 13 home runs and 140 runs batted in over 1,719 at-bats. That is a reminder that National League pitchers once hit every time through the order.
What the historical record cannot tell you
The historical record is built from box scores and season totals, so there are several kinds of question that this profile cannot answer.
- Wins Above Replacement. The database does not include it, and so it can't say how much of Carlton's value came from innings or run prevention.
- Pitch data. The historical record has no pitch speeds, spin or movement, so statements about his slider are descriptions from other sources, not measurements.
- Park and era adjustments. Earned run average and ERA+ are not in the database; a reader who wants them needs to use a source that adjusts for ballpark and league.
- Negro Leagues. The Negro Leagues statistics the database does carry cover 1920 to 1948, which is before Carlton's career, so they do not affect his career totals, but they do matter for any all-time list of strikeouts or wins.
The honest conclusion is that Carlton's numbers rank him among the best left-handed starters of his generation, and that the 1972 season is among the most remarkable individual years in the database. The rest is a matter of taste.
