The End of a Dynasty

UPDATED

The Yankees' recent record [written 09/26/10] -- 4 straight losses, 6-12 in the past three weeks, .529 since the All-Star break -- suggests that their third dynasty may be drawing to a close [but not quite, see below]. It would be unsurprising if that turns out to be so. Where are the replacements for Jeter, Posada, Pettitte, and Rivera, whose average age is 38? A-Rod is close behind, at 34, and not the A-Rod of a few years ago. Tex, at 30, is on the cusp of decline, and his numbers show it. Of the younger generation of position players, only Robinson Cano exudes star quality. Curtis Granderson is no Bernie Williams; Nick Swisher, no Paul O'Neill.

The only reliable starter is CC Sabathia. A.J. Burnett and Javier Vasquez don't belong on a championship-calibre team. Phil Hughes isn't convincing, despite his 17 wins. The bullpen reminds me of a rowboat in a hurricane. Even Mariano has become a question mark.

Given the evident dearth of outstanding young players, the end of the present dynasty seems to be in sight -- or perhaps visible in the rear-view mirror. The 2009 World Series may have marked the end of Yankees Dynasty III.

Dynasty I lasted from 1921, the year of the Yankees' first AL championship, to 1964, the year of their 29th AL championship. There were some "down" years sprinkled throughout the period -- most notably, 1925, the year of the Babe's big stomach ache, when the Yankees finished seventh in the days of the eight-team league. But the Yankees never went more than four seasons without a pennant, and finished below third (in eight- and ten-team leagues) only twice. Overall record in 44 seasons: 29 league championships and 20 World Series championships.

Dynasty II lasted only six seasons: 1976-1981. The Yankees led their division in four of those years, and wound up with the AL crown in 1981, despite an overall fourth-place finish, thanks to the split season (due to a players' strike) and a post-season playoff to determine the division winner. Overall record in six seasons: 5 division championships, 4 league championships, and 2 World Series championships.

Dynasty III (on the current evidence) lasted 16 19 seasons: 1994-2009 2012. Overall record: 14 17 appearances in post-season play, 12 14 division championships, 7 league championships, and 5 World Series championships. (Don't forget that in 1994 the Yankees had no opportunity to compete for a league or World Series championship because a players' strike wiped out post-season play.) That's a lot better than Dynasty II and a lot worse than Dynasty I.

In the following graph [updated to include the 2011-13 seasons], the black line indicates the Yankees' finishes in the American League (1901-1968) or Eastern Division of the AL (1969-2013). The red, horizontal bars indicate the number of teams in the league or division, for each season. The blue shading highlights the years of the Yankees' dynasties, to date. It looks like the end for Dynasty III -- and end that coincides with the retirements of Mariano Rivera and Andy Pettite, the final declines of Jeter and A-Rod.

Team W-L Histories: 1901-2009

In the course of preparing the three preceding posts, I compiled the table below. Note that the American League's overall record is slightly better than the National League's. That's because of the AL's edge in interleague play, which continues into 2010.

A Simpler Pythagorean Formula

According to an article posted in the "Bullpen" at Baseball-Reference.com, the Pythagorean Theorem of Baseball
relates the number of runs a team has scored and surrendered to its actual winning percentage....

There are two ways of calculating Pythagorean Winning Percentage (W%). The more commonly used, and simpler version uses an exponent of 2 in the formula.

W%=[(Runs Scored)^2]/[(Runs Scored)^2 + (Runs Allowed)^2]

More accurate versions of the formula use 1.81 or 1.83 as the exponent.

W%=[(Runs Scored)^1.81]/[(Runs Scored)^1.81 + (Runs Allowed)^1.81]

An analysis of statistics available at Baseball-Reference.com, which include expected W%, yields the following straightforward version of the Pythagorean expectation:
W% = 1.8195*RS% - 0.4098, where

W% = games won/(games won + games lost),

RS% = runs scored/(runs scored + runs allowed), and

* indicates multiplication.

The Pythagorean formula used by Baseball-Reference.com bears a strong resemblance to the long-term (1901-2009) relationship between W% and RS%, which is:
W% = 1.8372*RS% - 0.4191

This equation is no longer accurate, however. Nor is any equation that neglects the evolution of the game through its six "modern" eras: Deadball (1901-1919), Lively Ball I (1920-1941), Wartime Lull (1942-1946), Lively Ball II (1947-1961), High Plateau (1962-1993), and Juiced Player (1994-2xxx). Here are the formulae for each of the six eras:

Deadball
W% = 1.7679 * RS% - 0.3843

Lively Ball I
W% = 1.8965 * RS% - 0.4482

Wartime Lull
W% = 1.7389 * RS% - 0.3686

Lively Ball II
W% = 1.8704*RS% - 0.4377

High Plateau
W% = 1.7521*RS% - 0.3760

Juiced Player
W% = 1.9882*RS% - 0.4940

This final equation seems like the one to use, until there is a marked change in the style of play. Results will vary from year to year, of course. Here, for example, is the equation for 2009:
W% = 1.9419*RS% - 0.4707

The Six Eras of Baseball

In the preceding post, I identified six eras of "modern" baseball:
1901-1919 -- Deadball ("modern")

1920-1941 -- Lively Ball I

1942-1946 -- Wartime Lull

1947-1961 -- Lively Ball II

1962-1993 -- High Plateau

1994-2xxx -- Juiced Player
These six eras have distinctive characters, which are captured in the following table:





Change from 1901-1919


Runs per HR per Add'l runs Add'l HR Runs per
Era # Teams game game per game per game add'l HR
1901-1919 16 7.84 0.30


1920-1941 16 9.69 0.97 1.85 0.67 2.76
1942-1946 16 8.14 0.88 0.30 0.58 0.52
1947-1961* 18 8.91 1.62 1.07 1.32 0.81
1962-1993** 26 8.37 1.56 0.53 1.26 0.42
1994-2009*** 30 9.62 1.63 1.78 1.33 1.34







1994-2009 "old 16" 9.73










1901-2009 30 8.82



1901-2009 "old 16" 8.85










* 2 expansion teams in 1961



** 2 expansion teams in 1962; 4 in 1969; 2 in 1977; 2 in 1993
*** 2 expansion teams in 1998




Lively Ball Era I was the most dynamic era to date. There were more home runs than in the Deadball era, to be sure, but it is evident that much of the "small ball" action of the Deadball era carried over into Lively Ball I.

The Wartime Lull was just that. There were more home runs than in the Deadball era, but every home run netted only 0.52 runs on the scoreboard. Think of batters reaching base and mostly waiting around for a home run to be hit, usually to no avail.

The next two eras -- Lively Ball II and High Plateau -- saw a resurgence of home-run hitting, but run production didn't return to the level of Lively Ball II. Again, there was a lot of waiting around for home runs, usually to no avail.

The era of the Juiced Player rivals (but falls short of) the dynamism of Lively Ball I. Yes, a lot more home runs per game (what would you expect?), but not quite the same number of runs per game.

I have always had the impression that baseball in the 1920s and 1930s was baseball at its exciting best: power added to the "small ball" wiles of the Deadball era. The numbers seem to confirm that impression.

EXTRA INNINGS:

The runs-per-game figures for the "old 16" teams -- the franchises in existence from 1901 through 1960 -- suggest that those teams have done better than the expansion upstarts. In fact, for the Juiced Player era (1994-2009), the "old 16" have a W-L record of .512.

But not all of the "old 16" have fared well. Here are the W-L rankings of the "old 16" for the period 1994-2009:

Rank (of 30) Team G W L W-L%
1 NYY 2524 1514 1007 .601
2 ATL 2525 1456 1068 .577
3 BOS 2526 1409 1117 .558
4 CLE 2523 1353 1170 .536
5 STL 2525 1347 1176 .534
7 LAD 2526 1336 1190 .529
9 OAK 2524 1312 1212 .520
10 CHW 2527 1312 1212 .520
11 SFG 2526 1310 1215 .519
14 PHI 2526 1260 1266 .499
17 MIN 2525 1251 1273 .496
19 CIN 2530 1232 1295 .488
20 CHC 2524 1230 1294 .487
24 BAL 2525 1175 1347 .466
27 DET 2526 1108 1418 .439
28 PIT 2523 1091 1431 .433

"Old 16" teams occupy the top five spots and 10 of the top 15 spots. But Baltimore (13 straight losing seasons, 1998-2010), Detroit (12 straight losing seasons, 1994-2005), and Pittsburgh (18 straight losing seasons, 1993-2010) have turned in especially embarrassing performances.

The Lively Ball Eras

It is generally thought that the lively ball era began in 1920. In that year, the number of home runs per major-league game jumped to 0.511, eclipsing the previous "modern" high of 0.411, set in 1911. But the home-run barrage was only beginning in 1920. It jumped to 0.762 per game in 1921 -- nearly double the 1911 mark -- and continued around a rising trend through the rest of the pre-World War II era:

Despite Babe Ruth's dominance in the early years of the lively ball era -- he hit almost 9 percent of ML home runs in 1920, and more than 6 percent in 1927 -- it wasn't until 1931 that the AL began to outslug the NL every year. But there was plenty of slugging to go around, as the peaks and high valleys of 1930-1941 attest. I attribute the higher home-run output of those years to arrival of a new generation of players, who were selected more often than not for their slugging ability and encouraged to cultivate that ability.

But the real lively ball eras were yet to come:

Following a lull from 1942 through 1946, the home-run barrage resumed in 1947, with the post-war return of slugging veterans and the influx of newcomers raised in the slugging tradition. The second lively ball era peaked in 1961. It subsided with the "era of the pitcher" and the first waves of expansion. But even at its lowest ebb in the 1970s and 1989s, the pace of home-run production exceeded the peaks of the first lively ball era, with only a few exceptions.

Then came 1994 and a third era. This one, sad to say, probably owed its existence not to a "juiced" baseball but to "juiced" baseball players. Given the crackdown on performance-enhancing substances, the rate of home-run production in 2010 (to date) has dropped to that of 1961 -- when the "juice" in the game came from a performance-inhibiting substance known as alcohol.

I hereby declare the following eras:
1901-1919 -- Deadball ("modern")

1920-1941 -- Lively Ball I

1942-1946 -- Wartime Lull

1947-1961 -- Lively Ball II

1962-1993 -- High Plateau

1994-2xxx -- Juiced Player
