Here's something I wouldn't have guessed ...

Park Factors with large differences between HRs by LHBs & RHBs:


PARKHR-LHBHR-RHB
ASTROS84116
A's97114
CUBS97137
D-RAYS9875
MARINERS11396
METS11577
BoSOX76105
ROX147127
TIGERS9374
CHISOX121137




Data from 2002-2004:
100 = "Neutral". 100+ = favors hitters, lower than 100 = favors pitching

Represents only how the park has influenced [u:93d2f6376a]HRs[/u:93d2f6376a] in that time, not runs in general and shows only those parks shown with a 15% or greater difference in HR per 'handedness'.



I wouldn't have figured Shea to give an advantage to either side over the other.

The wind blows in from LF, especially in April. That hurts righty power hitters.

I thought I'd read that before too. The other thing I understood was, that while Shea tends to depress offense in general, it depresses actual hits (singles, doubles, triples) to a greater degree than it does home runs. This doesn't seem intuitive, but I suppose it's possible given that Shea plays 15% better than the average park for LH HR hitters, as shown above.

The fact that it depresses RHB-HRs to a greater degree than it helps LHB-HRs and that there are more RH-ABs than Left implies that it does also depress HRs overall.

I was just surpised by the disparity between the two. Yeah the wind blows in - during the spring especially - but I never thought of it as primarily affecting one side more than the other.

Among other factors too subtle for me to speculate on, I imagine part of the reason is the giant windscreen in right center.

Thanks, I had heard that over the years, but never saw the numbers.
I love it when posters on other boards used the "Shea is a pitcher's park" arguement when discussing a power hitting acquisition without looking into the splits you just posted.

How many years left on Floyd's contract? He's signed through 2006 right?

Yup. That's what this article was essentially about:

So it's not that Shea is a pitcher's park, but that the Mets can't hit for shit.

Did I mention that I'd really like us to sign Adam Dunn?

Pretty please, with sugar on top?

Strawberry dug that windscreen.

Strawberry & Dunn don't need the windscreen. They could hit the ball out of any park and that includes Yellowstone.

I'd like to see if those numbers change if you add more years. The White Sox park is friendlier to righties than Colorado? I find that hard to believe (although I just cut the amount of money I'd be willing to spend on Paul Konerko this offseason by about two-thirds). Does anybody know where the rest of the league's stadiums fit?

Stuff I've read on this topic over the years seems to indicate that a 3-year sample is usually sufficient to get you a true rating while 1-year samples can vary wildly - although things certainly could change w/a larger sample.

And remember, this is just measuring HRs not hitting or run-scoring in general. One thing about Cape Coors is that not only does it boost HRs, but that OF is so large that singles, doubles & triples increase as well (except during Monday & Tuesday of this week of course).

Am I right then in concluding that a theoretical park that gets an 85 rating against righthanders and a 115 rating against lefthanders is still a below average homerun park net, due to there being more righthanded batters?

Or am I over-thinking this thing?

Or would that wash because there are a larger percentage of home run hitters batting lefthanded?

Or am I really over-thinking this thing?

Edgy, I would think that you are correct that the higher number of right handed hitters would skew the overall park numbers, the best mathematical term I can come up with is the weighted average. That's probably why Shea is considered a pitcher's park.
