Here's my last run estimator piece, discussing BaseRuns.

Check out this new blog - some interesting visualizations

Crasnick is surprisingly one of the more progressive baseball people on ESPN, as he regularly cites FanGraphs and defensive metrics in general when doing his list articles.

I liked his take, I think it is what most of us believe. We need scouting and metric data to estimate defense, and in the future we may have quantifiable answers to things like "What's the difference between line drives and fly balls?" How much we weigh each data set is what is currently in contention, I suppose.

Had to see if breaking pitch sponsored Miguel Olivo after seeing #1. Looks like I may be out $15 today.

Hat tip to BBTF.

Intro to Saber 101 has the advantages/disadvantages of linear weights. As always, if I got anything wrong, please point it out. Thanks.

I'm not sure what the make of this. I'm pretty sure it's wrong, though.

More discussion at Tango's blog.

The site Fonzie Forever uses Fangraphs data to point out some interesting things about the cut fastball. 17 starters use the cut fastball and they happen to be an elite group. For half of them, the cutter is the most effective pitch, and for none is it the least.

Do these statistics make a convincing enough case for the pitch to become more widespread?

Great discussion on the limitations of WAR. Make sure to read the comments.

All of these cool statistical techniques didn't just magically appear, y'know.
