Batting Order by The Book

The Book‘s batting-order advice:

Your three best hitters should bat somewhere in the #1, #2, and #4 slots. Your fourth- and fifth-best hitters should occupy the #3 and #5 slots. The #1 and #2 slots will have players with more walks than those in the #4 and #5 slots. From slot #6 through #9, put the players in descending order of quality.

The Book admits a slight advantage in batting the pitcher eighth.

home-field advantage

One thing caught my eye in the Curve Ball book: batters playing at home hit 12 points better than on the road. Makes sense, but it’s almost as big as the lefty/righty match-up difference, which they say is 15 points. And yet, AFAIK, there are no adjustments in TPB to take home-field advantage into account.

A quick run of the Retrosheet game logs proves the home-field advantage for wins & losses:

              HOME WINS       ROAD WINS
            --------------  --------------
1960-1969    8603 (54.03%)   7319 (45.97%)
1970-1979   10644 (53.78%)   9149 (46.22%)
1980-1989   10995 (54.12%)   9320 (45.88%)
1990-1999   11554 (53.52%)  10033 (46.48%)
2000-2006    9166 (53.93%)   7831 (46.07%)

1960-2006   50962 (53.86%)  43652 (46.14%)

It’s almost 8 points. Not as large as 12, but, of course, there’s more to winning than hitting!

2007-10-07: The Commish’s comment re capturing home-field advantage in Park Effects is very interesting. I might even replace the LHB/RHB categories with home/visitor.

Curve Ball: Baseball, Statistics, and the Role of Chance in the Game

Didn’t expect it, but this book starts out with a simple analysis of All-Star Baseball, APBA, SOM & Sports Illustrated Baseball! Interesting point about the SOM method of splitting the rolls: the batter’s ability is purely additive, that is, there’s no direct interaction with the pitcher. You can get some of that with pitcher symbols in TPB, of course.
