Hill's Curve and the Weather

I'm hoping/assuming Hill will have a better than average curve tonight, given the humidity and the wind forecast. I decided to gather up his curves from Wrigley and put them against the weather conditions.

Since 5 of his 7 starts had the wind blowing in from somewhere, I eventually combined all 3 "in" directions into 1, and the two "Not In" games. No humidity data (I can get it, but, I gotta be someplace @ 5:07).

I need me a good stats package to do some fancier analysis.....but this looks like a better curve. Also consider both the "Not In" games are from September and only one of the "In" games is, but good luck controlling for that with this sample size.









This is a good enough reed for me to cling to, at least until game time.

Harry, are you aware of this work by Alan Nathan? He talks about the effect of wind on a curveball.

This is from a freshman physics course that Dr. Nathan is teaching at the University of Illinois. The whole lecture series can be found here:
