I initially created Baseball Graphs to develop new and better ways of presenting baseball statistics. The 2003 season was my first full-season attempt, and it turned out pretty well. I now spend a lot of my time creating and formatting the baseball stats at The Hardball Times.

Along the way, I've also picked up the writing bug. I spend most of my energy writing for THT, but sometimes I like to write about more geeky stuff, baseball research and things like that. That's what this blog is for.

I'm very interested in graphics and other information display, so I'll probably post links to creative stuff like that. I also plan to write historical articles that complement the historical graphs. And I have inexplicably developed an interest in baseball win-related stats, such as Bill James's Win Shares and something called Win Probability Added. So you can expect a few posts about that stuff too.

If you're interested, I've created a complex spreadsheet full of WPA logic, which you can download at ftp.baseballgraphs.com/wpa. If you'd like to read more about Win Shares, try these links:

Towers’ Trade Record

December 05, 2006

Geoff Young has a great post at Ducksnorts, including a Win Shares Balance Sheet of general manager Kevin Towers’ trades. I assumed Towers would look good in an analysis like this, but I didn’t know he would look this good:

* positive win shares: 46 trades (average gain, 17.5)
* no difference: 3 trades
* negative win shares: 40 trades (average loss, 8.65)

I also would have guessed that his big trade with the Braves (netting Ryan Klesko, among others) would have ranked first, but it’s second to his acquisition of Phil Nevin earlier in 1999. I had completely forgotten Nevin played for the Angels.
