An in-depth look at Mets minor league park factors

What does the run-scoring landscape of the Mets minor league system look like?

College Baseball Park Factors


The idea that the park in which a game is played affects baseball statistics, both individual and team, has been accepted for years. There is plenty of literature available on park effects at the...

HR/OFFB Park Factors


An look at homeruns by outfield fly-ball instead of using just "fly-ball" data that includes infield fly-balls. Progressive Field ranks as one of the lowest with regards to inflating homeruns per outflield fly-ball. Interestingly, Petco isn't the lowest, though it is second lowest. New Yankee Stadium has the highest park factor for homeruns per outfield fly-ball. There's also a little unrelated tidbit in the beginning of the article that I didn't know. The author writes that Fangraphs is inconsistent in their K% and BB% metrics, as they use K/AB for the K%, but BB/PA in the BB%.

Ever wondered how your favorite team's park affects triples? Doubles? Homers? Strikeouts? Here are those data!

Revisiting AT&T Park's Affect on Hitters


People seemed to get a kick out of my component park factors from a while back, so I thought I'd update them and include ALL seasons, not just '05-'09. In sum: right-handed hitters don't see a big drop in production- about 2%. Left-handed hitters see about a 5% drop, which is bigger than what I found in my initial "study."

In a great article in Hardball Times annual, Greg looks at the batted balls at the new Yankee Stadium and Citi. The interesting finding is that while Yankee Stadium turns long flyballs into HR, it also turns almost-long flyballs into outs. Citi field however turns almost-long flyballs into hits. So, this would be an example of where the HR park factor and the Runs park factor on non-HR are not directly related (either unrelated, or inversely-related).

Citizens Bank does allow home runs, but you might be surprised to see how it acts when looking more closely

The Carry of a Fly Ball


There was much discussion in the early weeks of the 2009 MLB season about the large number of home runs hit in the new Yankee Stadium, leading to speculation that many of the home runs were aided by strong wind currents. Or, in the lingo of baseball, the ball was "carrying well" in Yankee Stadium. All this discussion stimulated me to ask the question, "Just what is meant by 'carrying well'?" Of course, we all have an intuitive notion of what this means. We observe a fly ball coming off the bat and have an expectation of how far the ball will travel. If the ball traveled farther than this expectation, we say that the ball carried well. And of course, vice versa. But can we come up with a more precise, less intuitive measure of "carry"? It is precisely this issue that led to the analysis presented in this report.

On Baseball: Additive Park Factors


Justin of On Baseball and the Reds adds a nother part to his player value series with an improvement in park factors. He helps negate the disparity between good hitters and weak hitters that comes from ratio park factors by using regressed 5-year park factors to make an additive form. Essentially, how many runs a park affects a typical player per PA, and then adding or subtracting that from a player. Not only does it make sense, it's also extremely easy, and he puts it in an ultra-nifty table. Good times! Also, I did not realize Arizona was the best non-Coors park for hitters.
