Excuse me?
Does this mean you have bypassed most of the other posts?
Let's go step by step:
Number one:
His road performance was a fuke:
Both ORS and i pointed this out in posts made before. He hit above his career averages in BABIP on the road, and also hit an inordinate amount of XBH on the road, pumping his SLG waaaay above his home numbers.
And also, as noted in a post above, most of those XBH came in AL East stadiums! (and he played a grand total of 19 games in the AL West, a SSS that wouldn't have a third of the impact when compared to the division he actually played in ) maybe you simply glanced over it, so let me post it again.
Let's break down his numbers by ALE and other divisions:
Beltre's overall numbers:
.321/.365/.553 49 2B, 28 HR, 2 3B, 189 hits.
Now let's check out his numbers in Fenway:
.314/.351/ .881 19 2B, 13 HR, 0 3B. (By the way, this is the first part of the massive hole in your argument, since his career home OPS is below .800, so even the boost to his home stats was massive).
Now let's get into the meat of the argument: Total Bases.
To calculate Slg% you can simply divide total bases by AB's, therefore, the number of total bases is what inflates your slugging percentage, which is what created the massive statistical difference in his home/away splits (which wasn't even that massive, but don't tell anyone).
Here's the thing:
Beltre collected 72 TB's against the AL East in less than 50% of the AB's. (140) than he collected against the rest of the stadiums with a SLG%: of 512. The issue with this is that, while it makes a part of your argument correct (He wasn't just feasting on AL East stadiums) it also undermines another part of your argument. Beltre did almost of his damage in stadiums which had a positive park factor for RHH (you can verify that by going to hit tracker and checking out the amount of XBH hit by righties in any given stadiums when stacked up against lefties as well as common sens) last year with the exception of Oakland and Seattle.
Beltre SLG% by park and their park factor:
(I'm using three-year park factor and XBH data for the rankings):
1) Coors Field: (1st) SLG% 1.000
2) Oakland Coliseum: (19th) .875
3) Angel Stadium: (13th) .769
4) Citizens Bank (11th) .727
5) Camden Yards (5th) .667
6) Rogers Centre (8th) .636
7) Tropicana Field (15th) .611
8) US Cellular (4th) .600
9) At&T: (12th) .600
10) Kauffman: (10th) .556
11) Rangers: (3rd) .538
12) Fenway: (7th) .521
13) Comerica: (17th) .444
14) Yankee: (2nd) .243
15: Target: (16th and single-year data) .231
By compiling some information about the amount of XBH (mostly HR's and 2B's) in www.hittracker.com and www.mlb.com (most of which i had handy from a previous park factor discussion) i was able to highlight the parks that are most conductive to RHH power (which are highlighted above and the "launching pads" italicized), and we can come to the following conclusion, and it's that Beltre, a RHH, performed reasonably in parks conductive to RHH power than in stadiums much more suited for LHH power (Comerica, Yankee, Target, which are coincidentially the bottom 3) and also hit the lights out of the launching pads.
Combine that with the fact that on the 3 stadiums in the AL East where RHH boast the best power boost (Fenway, Rogers, Camden) he had a composite .636 SLG% over 347 AB's. And if we include Tropicana that could be characterized as "neutral" in terms of both Park Factor and XBH ratio, we get the following: .550 SLG. Now i could go into greater detail about how he performed notably better in stadiums that are known conductors for RH power (US Cellular) or those that surprised me (AT&T), but know this, the way a park is constructed does influence how a hitter hits and how much power he generates on a stadium-by-stadium basis, and this is why players need to be analyzed depending on the environment they play in.
Also, your initial argument was that the "FO got lucky with Beltre's production" which was disproven long ago, since you admitted that they were probably expecting increased production from Beltre (even admitting you did expect a mid- high .800 OPS out of him) but that production was inflated by a fluky road performance, while you conveniently ignored the fact that his home production had also spiked to near-2004 levels.
In conclusion, Beltre, like most hitters, is affected by the park they play in if said park has extreme factors, and this research has been very informative for me, and i expect it to be so for you as well even though, to be honest, i did all of this research strictly out of boredom while i wait for my friends to get out to class so we can go clubbin'.
That is all, smart-ass.
