Today’s Enquirer contains the following note:

LONG BALL: Great American Ball Park, so far this season, is the most home run-friendly park in Major League Baseball.

Entering the game Friday night, according to STATS Inc., there were 23.53 at-bats per home run at Great American. Ameriquest Field, home of the Texas Rangers, was second at 23.95.

RFK Stadium, home of the Washington Nationals, has been the most difficult place to homer. There have been 62.36 at-bats per home run.

I couldn’t help but immediately wonder how informative this information actually was. I can only assume that the above numbers include the home team, which means that the home team provides half of the sample for the statistic. It appears obvious that these numbers would be highly skewed to lean towards the makeup of the home team. Which in the Red’s case, we have a power laden offensive team, and a porous pitching staff prone to allowing the gopher ball. So are these numbers the result of the makeup of the Reds ballclub, or are the Reds numbers a result of the park effects? I would tend to believe the former would be the case. I propose that these numbers would be much more informative if they were derived from only the visiting teams numbers.

    Don’t look at ERA, look at RA. ERA is flawed by official scorers.
    Second, park effects affect different types of pitchers, differently. Flyball pitchers were markedly worse last year. (about 1 run worse), the others were basically the same (small sample size).
    Now I understand that was last year and there isn’t enough of a sample size to make a strong conclusion. However it is evidence that flyball pitchers are not good for the park as compared to ground ball pitchers or even nuetral pitchers.
