NYTimes Profiles the Science of Simulation

With the 2009 baseball season underway, today's New York Times Science section covers baseball's "what ifs," exploring the science of simulation -- and how close to the real-life game it actually is.  Imagine Sports' Diamond Mind simulation plays a significant part inthis article.  Here are a few quotes and points to highlight from the piece, written by Alan Schwarz:

“Computer simulations work pretty well in baseball for two reasons,” said Carl Morris, a professor of statistics at Harvard University who has written several papers that commingled baseball and formal statistical theory. “In general, they allow you to study fairly complicated processes that you can’t really get at with pure mathematics. But also, sports are great for simulations — you can play 10,000 seasons overnight.”

Luke Kraemer of Imagine Sports, which owns Diamond Mind, programmed the simulator to force the 2008 Yankees to bat their best hitter and cleanup man, Alex Rodriguez, ninth — to see how scoring was affected. Mr. Kraemer got the run total not for just one season, which can fluctuate as much as 80 runs in each direction from simple randomness, but for 100 seasons — more than 16,000 Yankees games in all.

The result? The Yankees scored 747 runs per season, 40 fewer than their real-life 787. (Diamond Mind was so accurate that 100 seasons with A-Rod batting fourth averaged 789, almost dead-on.) Most research suggests that those 40 runs would mean only about four fewer victories, for a strategy no manager would ever consider; so the difference with Rodriguez batting third or fifth would be insignificant, and nowhere near worth the forests of trees that would give their lives to the ensuing sports-page debate.
