MLB Team Travel
One interesting aspect of the proposed realignment is the effect it will have on team travel. As Dave Cameron noted without division there would be fewer games between geographically close teams, and more between teams farther way from each other — travel will increase. Last Thursday On the Forecheck, a hockey blog, posted the total distance each NHL team will travel in the upcoming 2011-2012 season (hat tip Tango). That made me think that, in light of realignment, it would be interesting to see how much teams are already traveling — and how much variation is there between teams — as a baseline for the current system.
I wanted to get a broad picture of travel distances for each team under the current system, so rather than use just one year’s worth of data I looked at all seasons from 2005 (when the Montreal Expos became the Washington Nationals) to 2011. I counted how many miles each team traveled and also the number of miles traveled on trips taken without a travel day (i.e., back-to-back games). Since this no-off day travel should be especially grueling. Here are the results averaged over the seven years, thanks to retrosheet for the data:
