TAA 8 – What Are Park Factors Worth?

Nate and Kyle are joined by Sara Sanchez to talk park factors.

 

Nate Schwartz (@_nateschwartz) and Kyle Bland (@blandalytics) are joined by Sara Sanchez to talk about park factors.

The discussion starts with the group talking about what goes into park factors and what they actually mean. They discuss how specific factors, such as HR or strikeout factors, can be more important than the overall factor at times. They also talk about how the weather can get baked into some park factors and ignored in others (such as the wind in Wrigley). Next, they get into how players prepare and adapt to different parks, both offensively and defensively. Finally, Kyle explains how park factors get integrated into daily & weekly projections, and Sara talks about how controlled environments in domes is good for pitchers.
