Results derived Interleague Play and Two League Players
 
- also a sneak look at best teams ever up to 1968

Were the 2009 Yankees be the greatest team of all time – or is it still the 1998 Yankees? How do they compare to the 1975-1976 Big Red Machine? The 103 game wining 1968 Tigers beat the National League dominating 1968 Cardinals in the last World Series before the 2nd wave of expansion and divisional play. Were they even better than the 1967 Cardinals who did win the World after winning 101 games during the season? And, were those Cardinals better than the 1961 Yankee champions who won 109 games the first year of expansion – or the mythic 1927 Yankees? These questions propelled me to work on a history of baseball exploring which teams were the greatest compared to all teams before them. While working on this project, I had to make reasonable estimates as to how much to penalize (or reward) a team’s accomplishments in one league to make it a reasonably fair comparison to another team in the other league.

 

Mostly all I had to go by are All-Star game and World Series results. However, we have had 14 years of interleague play now to give us a good idea of the current balance between the two leagues. During the first four years of interleague play 1997-2000, the leagues alternated with the National League winning more often against the A.L. in odd years and the A.L. besting the N.L. in the even years. However, the difference – 20 games when spread across the 14 or 15 teams doesn’t merit crediting all the teams in that league with an extra win for their superiority. After that, the American went back to unbalanced schedules. From 2001 on, we can narrow the appropriate handicapping down to the specific division. I calculated that for every 17 games an entire division is above .500, each team in that division deserves an extra game (+1 W – 1 L). So, here are the number of games to be awarded or shaved from each candidate for best team over the past decade:

 

2001: A.L. East -1, A.L. Central -1, A.L. West +2

2002: A.L. East   E, A.L. Central -3, A.L. West +3

2003: A.L. East +1, A.L. Central -2, A.L. West +1

2004: A.L. East +1, A.L. Central -1, A.L. West   E

2005: A.L. East +1, A.L. Central   E, A.L. West   E

2006: A.L. East +1, A.L. Central +2, A.L. West +1

2007: A.L. East +2, A.L. Central   E, A.L. West   E

2008: A.L. East +2, A.L. Central   E, A.L. West   E

2009: A.L. East +1, A.L. Central -1, A.L. West +1

2010: A.L. East +2, A.L. Central   E, A.L. West -1

 

Using Two League Players to find differences (Cross-League Study)

Besides just relying World Series results and All-Star game results to find league superiority in the years before interleague play, another method is to look at the players who changed leagues. Joseph Reichler’s The Baseball Trade Register lists every trade of the 20th century up through 1984. Let’s look at the players who had unexpected improvement or disappointment after they changed leagues. I will start from 1962 when leagues first expanded (and when I became a baseball fan) and end in 1979 which I marked as the last year of National League dominance. Listed below are the two year ERA+ or OPS+ in one before or after the player changed leagues along with the number of games/innings and his age followed by the same stats in the league he switched to. Due to mid season trades, injuries, and brief stints in the minors, I don’t always have exactly two years of data, but I came as close as I could. Note that park factor, change in strike zone are accounted for in ERA+ and OPS+. Those are their ERA and On-Base Average + Slugging Average normalized by their park to the league average that year as 100. So, 75 is considerably below average and 125 is well above average. The player has to have played, at least, a year and a half in opposite leagues surrounding league switch in order to be included.

 

They are sorted roughly by how unexpected the differences are given their age and history. I did not base those rankings strictly on their two year data as I found players are much more inconsistent than I thought. Sometimes, you have to look at further back in his career to notice he had the potential to be that good, although, I do consider that the older the player is and further back in history his comparably good season was, the more we need to recognize that the league switch may have helped or hurt him. In order to best measure these league differences, I divided the list in two, so the players in the upper list get credit for a more solidly based improvement (or decline) following their league switch. Really, even the most pronounced differences look plausibly coincidental, so I give the upper list only 2 points worth of credit and the lower list 1 point. Nolan Ryan was the hardest throwing pitcher in baseball during his first few seasons with the Mets. He just learned to pitch, however, when he came over to the Angels. If a player was a full timer and had a whopping career year or a major comeback after several lesser years or has a more consistently improved or degraded level in the new league, he generally makes the two point list. Players who have those attributes, but do not quite play every day – as well as full timers who’s improvement or decline is less pronounced get one point.

From 1962 to 1979 thirty-eight cross-leaguers played surprisingly well in the American League; only seventeen played better in the National League. Counting the more pronounced improvements or declines double, the American League earned 60 points, while the N.L. earned 26. Hence, this data certainly backs up the conclusion most of us reached based on all-star game results: the National League was, indeed, a superior league those decades.

 

Was the difference even more pronounced in the 1960s just as I accounted for? Yes, although we have fewer cross-leaguers to go by and the difference relative to the 1970s is not large enough to be completely conclusive. Using the same point system, the 1960s A.L. advantage was 17 to 6 (2.83), while the 1970s advantage was a smaller ratio of 43 to 20 (2.15). Keep in mind that the vast majority of cross-leaguers showed no significant difference, so penalizing A.L. teams two wins and two losses in the 1960s and one win and one loss in the 1970s remains a reasonable estimate.

 

Other conclusions from the cross-leaguer study

There are some interesting observations to make in that data gathered above that are not germane to what I was looking for. Of the pitchers who changed skill levels when they changed leagues, twice as many improved as declined. The position players did even better having a three to one chance of surprisingly improving instead of declining. For both pitchers and batters, the ages where you will most reliably see unexpected improvement is in the 28-33 range. The two catchers in the study were only 25 and 26 and they significantly declined (Milt May and Earl Williams). The two pure relievers in the study were both old (32 and 35) and they both improved (Lindy McDaniel and Stu Miller). However, pure starting pitchers were as reliably successful as position players, while pitchers who moved back and forth from the pen had only a 4 to 3 (8/6) rate of surprising improvement to speedy decline. All five middle infielders in the study improved nicely and they were all in the latter half of their primes (28-31: Felix Mantilla, Lenny Randle, Davey Johnson, Denny Doyle, and Cookie Rojas).

 

There are many more nuances to examine before determining the best teams ever. I am working on it. I had reported on the years 1892-1946 in two parts earlier this year, but took it down. I was hoping to get it all done by Christmas, but I don’t see that happening. I’m having too much fun researching historical anecdotes – and generally not successful enough at carving out time from the rest of my life for it. I’ll be lucky if I can finish editing my work up to 1968. I haven’t even reached 1999 in my rough draft. However, I can give you a little cheat . . . Here are the teams that managed to rank as the best of all teams that ever came before them up until divisional play. The ’67 Cardinals and ’68 Tigers were very close, and they both easily beat the ’61 Yankees, who did deserve the accolade as best ever up until them. Note: the Boston Beaneaters franchise is now the Atlanta Braves. The Baltimore Orioles listed here are not the franchise we know by that name now. The 1896 Orioles franchise of Hit ‘Em Where They Ain’t Wee Willie Keeler’s Baltimore chop fame died in 1899.
