Great New Resource, Saber Archive

Click here to go to the sight. It is searchable by topic and author. Looks like it has at least 150 articles. Tom Tango says "Out of all efforts I’ve seen to create a SABR library, this is the best one I’ve seen."

 The correlation between non-close & late (CL) AVG and the difference between it and actual CL AVG is -.076. So the better hitters see an even bigger dropoff than the lesser hitters, although the effect is slight. For SLG it was -.443. So the guys with higher SLGs normally see a big dropoff in CL cases. Maybe because they are facing good relievers or don't often have the platoon advantage.

The correlation between non-close & late (CL) AVG and the difference between nonCL SLG and actual CL SLG is -.078. The correlation between non-close & late (CL) SLG and the difference between nonCL AVG and actual CL AVG is -.309. So sluggers see a big drop in their AVG when it is CL.

 The correlation between non-runners on base (ROB) AVG and the difference between it and actual ROB AVG is -.229. For SLG it was -.053. Not a surprise since that this is low because the correlation between ROB SLG and non-ROB SLG is very high (.936).

The correlation between non ROB AVG and the difference between non ROB SLG and actual ROB SLG is -.154. The correlation between non ROB SLG and the difference between non ROB AVG and actual ROB AVG is -.134. So sluggers see a big drop in their AVG when it is CL.

 The correlation between non-runners in scoring position (RISP) AVG and the difference between it and actual RISPAVG is -.292. For SLG it was -.279.

The correlation between non RISP AVG and the difference between non RISP SLG and actual RISP SLG is -.284. The correlation between non RISP SLG and the difference between non RISP AVG and actual RISP AVG is -.158.

How Fluky Was The 2005 White Sox Pitching Staff?

Very fluky. That is based on their team ERA+ in the year they won the World Series (2005), in the year before and in the year after. There have been seven World Series winners since then for whom we can do this kind of comparison (we can't do the 2013 Red Sox, since their year after has just started). So I looked at the 2005 White Sox, the seven teams to win the series before and the seven since.

The table below shows ERA+ for the World Series winners in their year, the year before and after. ERA+ is relative to the league average and is adjusted for park effects. Over 100 is better than average so 110 means your team was about 10% better than the league average.

The White Sox improved by 29 in the year they won and then fell by 22 they year after. Only three other teams saw a gain of at least 10 and then a dropoff of at least 10 (2002 Angels, 2004 Red Sox, 2008 Phillies). The 2000 Yankees and the 2011 Cardinals actually did worse in their year than both before and after.

As an index of "flukiness" I multiplied the difference in ERA+ in the year before times the after difference. So the White Sox get a flukiness score of 638. The 2004 Red Sox were 2nd with 240. 9 of the 15 teams were less than 100 (including some that were negative).

I also looked at all the teams that had the best record in each league over this time period that did not win the World Series. Here is the AL

The highest flukiness score from these two tables is the 2011 Phillies who had 352. They and only 3 other teams had gains and dropoffs of at least 10 in both years (2001 Mariners, 2007 Indians, 2012 Nationals). So again, the 2005 White Sox were much flukier than anyone else.

The next table shows the ERA+ in each of the three years for all White Sox pitchers that had at least 20 IP in 2005.
