I know this post is supposed to be about opening day, but there was one more thing I wanted to do before turning my attention to the current season. Peter Jensen's amazing series on using the Gameday data to build a fielding metric prompted me to get that data and play around with it. The first thing I wanted to do was make a run value by hit location map. It seems only right to present such images for the two closed New York parks as a way of saying goodbye before really getting into the new season.
I used Jensen's hit factors to translate gameday's pixel into feet, so the two images should be to scale. The run value should include all hits, outs, foul outs and HRs since 2005.
