Cameron: The hidden juggernaut in Oakland

From Dave Cameron at FanGraphs on June 14, 2013:

One of my favorite toys here on FanGraphs is the Past Calendar Year split. I like the rolling 365 day line, as it gives us a good view of what a player (or team) has done in the equivalent of the most recent full season they have played. Because the MLB season started earlier this year, the totals don’t work out to exactly 162 games, but it’s close enough to give you the right idea at least.

Just for fun, here are the win-loss records for every team in the American League, using the data from the past calendar year filter.


While the St. Louis Cardinals have steamrolled baseball for the first couple of months of 2013, the A’s have been winning games at an equivalent clip to STL for the past year. A .643 winning percentage over 168 games is an impressive accomplishment, especially considering that the A’s are still overshadowed by the Rangers, Tigers, Yankees, and Red Sox when people talk about AL contenders. However, none of those teams have even been with 10 games of Oakland over the last year.

Once again, Billy Beane, David Forst, Farhan Zaidi, and company have built a terrific baseball team despite limited financial resources. Unlike the A’s from the Moneyball era as chronicled by Michael Lewis, there really are no home grown “stars” that you can point to as the reason for the team’s success. This team was built almost entirely by acquiring undervalued assets via trade or free agency.
