First Charts

Durham Bulls 1; Gwinnett Braves 0
Season: 7-3; Streak: Won 5
Wrap, Box, Herald-Sun, Indy Week

I missed the game and the links have the story. So I’ll just leave it at that and put up my first charts of the year.

This one shows the game by game balance of runs scored by the Bulls minus runs scored against the Bulls. In the long run, this metric ends up being shaped very much like the won-loss curve for a team. What I look for is a trend. As you can see this is the best start for the Bulls in the last four years.

This one is for the boys in the bandbox down by the bay. They are on an upward trend, but have some ways to go to get back to even. Still, the trend is upward.

The last one is a look at ERA trends. This chart comes with a bunch of caveats — way early in the year, small sample size, etc. But it sure is pretty.

As a final grin, Fernando Perez scored the winning run for the Iowa Cubs yesterday.
