Stat corner: Ballpark effects

Ballpark effects, or park factors, are, in its simplest definition, a way to easily tell if a stadium favors hitters or pitchers.

A ballpark that is neutral has a score of 100, a hitter’s park is over 100 and a pitcher’s park is under 100. The numbers are calculated using the last three seasons and can change from season to season.

For years, Dodger Stadium was a heavy pitcher’s park, but after adding more seats and removing a great deal of foul territory, it has become more of a neutral park in recent years.

Now, a look at the teams with the best and worst hitter’s parks:
