One of my best friends, Derek Jacques, is a very good pool player. It was
from Derek that I learned the term "cripple stick," which is a
nickname for the bridge, a piece of equipment used to extend reach on
certain shots.

Writers have their own cripple sticks, one of which is the use of reader
mail to fill out a column on a day when ideas just aren’t coming.
Fortunately, the readers of this column are smarter than the actual
columnist, so the upgrade in quality should be noticeable.

Peter Friberg read
yesterday’s "column" and said:

I'd like to know what your commentary or "analysis" of your data
is. I noticed that the while Ks were up by roughly 0.5 per game, and BB
were down by nearly 0.5 a game for both leagues, the AL scoring decreased
by 0.5 while the NL only decreased by 0.2. Is this a statistical anomaly,
or if two new NL parks and one reconfigured NL park had that much of an
impact? I know your sample size is still relatively small, but I wondered
if you had any thoughts on that.

I was a little disappointed that you did not include the HR statistic.
Again with more HR-friendly ballparks, there may be an increase that has
little or nothing to do with the strike zone adjustment.

The biggest reason I ran the data without any commentary is that it’s too
soon to draw firm conclusions. While I feel the early strikeout and walk
data may be indicative of something, I almost left the data on runs out
completely. The sample size is microscopic and, at least in the NL,
distorted by the parks in which games have been played to date. That’s also
why I didn’t include home runs.

I want the data out there, and I will continue to update it, probably on a
weekly basis, because it’s part of a key storyline in the 2001 season. But
it’ll be a while before I’ll be willing to make any declarative statements
about the impact of the new strike zone on offense.

Two people wrote in about
the Wilton projection for Timo Perez.
Here’s one of the letters:

Wow! Just read the projections for NL rookies, and a Mets fan, very
encouraged by Timo's line. Do you guys really think he'll do that well
(which admittedly is still not great for a regular right fielder), or does
the caveat about [Albert] Pujols apply to Timo too? Thanks.

Wilton projections are a fairly accurate tool, but as with any projection
system, they’re only as good as the data with which they work. Timo
Perez’s projected .321/.377/.461 in 2001 is based primarily on two Japanese
League seasons and a good half-season in Triple-A. It’s also based on him
being 24 this season, something that’s been questioned.

I think it’s important to take Perez’s projection, along with Albert
‘s or, from the previous season, that of Ben Broussard,
with a grain of salt. I don’t think Perez will post a .291 EqA this year,
and I believe Baseball Prospectus 2001‘s comment on Perez makes the
issue quite important to me (go, run to your books!).

By the way, to answer another Perez question: yes, I believe he is eligible
for Rookie of the Year. I know he makes the playing-time requirement, and a
quick glance at the information at hand indicates he makes the service-time
