Another baseball season is upon us, and fans are quick to project the results of their favorite team from the first few games. I wondered if many teams tend to arrive at a winning percentage near their whole-season results, and then oscillate around a little, versus having early results that differ substantially from the final winning percentage.
I created an interactive plot to look at the results for the 2009 season, team by team.
Take Boston. Seen below, Boston started slow, but pretty quickly arrived at their ultimate winning level.
On the other hand, the Yankees started even slower, and in fact didn’t reach their ultimate winning level until very late in the season.
