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:

Shortstops and Defensive Win Shares

December 09, 2004

A review at Batter’s Box

The outstanding Blue Jays’ blog, battersbox.ca, has a nice review of shortstops by Mike Green. Mike and the pursuant commentators do a particularly good job of discussing the measurement of a shortstop’s fielding impact.

Bill James put boundaries on fielding Win Shares, at both the team and individual player, because he didn’t fully trust the output (I think). This makes it hard to use fielding Win Shares to evaluate really good (and bad) fielders in any given year or career. This is a significant issue that should be kept in mind when discussing some of the great ones, like Ozzie Smith.
