A Pitcher’s Park No More

August 2, 2012

When Target Field first opened in 2010, something unexpected quickly became evident. Although the park’s dimensions were somewhat modeled after the Metrodome, and the intent of Target Field was to be a ballpark that evenly favored both hitter and pitcher, everyone noticed that Target Field had seemingly become Petco Park Midwest. You didn’t need ESPN’s Park Factors to know that it was extremely difficult to hit the ball over the fence at 1 Twins Way, though Park Factors did confirm what we could see on FSN. Target Field’s HR park factor was 0.682, which demonstrated that Minneapolis was the hardest city to homer in all of MLB. To give you an idea of how this park factor is calculated, it’s:

((Home HRS + Home HRA) / Home G) / ((Away HRS + Away HRA) / Away G)

Home HRS = HR hit at home
Home HRA = HR allowed at home
Away HRS = HR hit away
Away HRA = HR allowed away
Home G = Home games
Away G = Away games
