I think that pitch selection is pretty interesting. I've written about it before, and will doubtlessly do so many more times until either all Rays fans discuss pitching in terms of Nash equilibriums or someone can convince me that another such delusional article would be essentially a hopeless waste of intellectual effort. (If you're not familiar with the concept, don't start by reading me. MGL has a much better explanation here on Fangraphs.)

I also really like pictures made from pitch f/x data. I've tried to give a comprehensive visual representation of how an individual pitcher works (here's one of Colby Lewis), but the problem with this method is that while it shows what the pitcher actually did, it does a poor job showing how well it worked.

Check out this prototype of a new graph model to supplement the strikezone plot. I used the recently acquired Fernando Rodney as my test subject. All input on how to make it better is appreciated.

After the Rays traded away John Jaso and signed Jose Molina earlier this week, I was left in a mild state of shock. I couldn't remember the last time Andrew Friedman had completed a trade this early in the offseason, even a small one like this, and I thought he normally liked to wait some time before signing players. But who knows, maybe my memory was wrong. It certainly wouldn't be the first time.

Thanks to graphics guru Josh Frank, though, we don't have to wonder any longer:

It looks like the Jose Molina signing was Friedman's first free agent acquisition ever during the month of November. Friedman seems to like letting the market settle some before making a free agent splash, but my guess is he wanted to jump on Molina quickly before other teams had a chance to digest the impact of Mike Fast's pitch framing study.

This has been an unusually active November for the Rays, so goodness knows what's ahead in December. Friedman is normally most active during December and January, although our intuition holds true: his busiest month of the year is January, late in the offseason and after the point where other franchises have called it quits. Therein lies one part of Friedman's success: he doesn't rush.

Any other observations? And again, a huge kudos to Josh Frank for putting this graphic together.
