1997 Ball Park Factors
First, I'll begin by stating that 1.00 is average. Less than 1.00 means that an event takes place less often. More than 1.00 means that an event takes place more often. You'll also notice that some of the park names aren't the names officially in use. I disagree with the new nom du jour policy in place in the Major Leagues. I understand the need to find new revenues. However, I fail to see the need to change a stadium name every few years for a few bucks. Parks are generally named due to their location (Fenway Park, Anaheim Stadium), team name (Tiger Stadium, Dodger Stadium), to pay homage to someone (Turner Field, Wrigley Park, Jacobs Field, Shea Stadium) or because of the type of park (Astrodome, Kingdome, Skydome). With sponsors changing more often than my kids' favorite toy, I'd like to keep at least a little stability in my life. It also avoids me the embarrassment of someday typing "Massengil's Disposable Douche Park".
Looking at the 1997 helps to show why I don't use AB to determine the factor. Examining COL (Coors Field), we see that Coors reduces both strikeouts and walks. This means that more balls are put in play than average which translates into more singles, doubles, triples and homeruns. But don't worry all you offense lovers, Coors doesn't stop there. When ball meets bat, Coors increases offense more than any other park in the Major Leagues. If we didn't use separate factors, we wouldn't realize this. Sure we'd know that ballparks influence things, but we wouldn't know what we know now. (Sure, you're thinking ..... and Peter Piper picked a peck of pickled peppers too.)
There's no reason to keep this info secret though. Tell your spouse. Let your friends in on the info. Don't worry though, there's no G.M.s watching. They're not smart enough to know about this page. Just ask Andre Galarraga's agent. :)
