He opined that (1) the effect of amphetamines should be most pronounced on day games after night games; (2) batting should be more affected than pitching, on the grounds that even Whitey Ford probably drank a little less the day before he was supposed to pitch; and (3) the effect should be bigger in the 1970-74 period than in the 2006-2010 period, since in the latter period there was testing; indeed, in the prior period I don’t even think it was illegal.
He then said: “Hey, JonathanF: you’ve put together a database of every baseball game ever played. Can you try it?” So I did. I really didn’t expect to see anything, so I was a little surprised.
Taking every game from those two periods, I compiled a simple TeamOPS number for every game (H+W)/(AB+W) + (H+D+2*T+3*H)/AB. I then compared the average teamOPS (simple averages here – you don’t do anything fancy when you don’t think you’re going to get anything) separately for day games after night games (which I called greendays) and all other games.
I did this year by year and got the following results. The “difference” column measures the team OPS difference between greendays and non-greendays. The bold results are statistically significant.
