In chaos theory, the butterfly effect is defined as “the sensitive dependence on initial conditions; where a small change at one place in a nonlinear system can result in large differences to a later state.” The effect derives its name from the theoretical example of the origin of a hurricane being dependent on whether or not a distant butterfly had flapped its wings several weeks before.

The above video is of C.J. Wilson flapping his wings back in July at the MLB All-Star Game. It was there that the Texas Rangers starter gave up a three run home run to Prince Fielder, costing the American League the game and ensuring that home field advantage at the World Series would be held by the National League’s representative.

Flash forward three months and the World Series is scheduled to start on Wednesday in St. Louis, the town that will play host for up to four games as opposed to Arlington, which will be the host city for at most, three games.

Strangely enough, it didn’t make much of a difference where the Cardinals played this season, as their equal records at home and away would indicate. However the Texas Rangers had a 52-29 record at home, and a 44-37 record on the road. That would make them tied for the second best home record in baseball with the New York Yankees and Philadelphia Phillies.

Technically, the Cardinals’ road record is a single game better than Texas’ record away from home. However, you could also say that the Rangers’ road record is only a single game worse than St. Louis’ record at home.
