One of the latest and most exciting developments in baseball research is the measurement and analysis of individual pitches. For instance, the Pitch f/x system created by the company Sportvision tracks the in-flight movement of pitches from two different cameras, thereby assessing a pitch's velocity, horizontal and vertical movement. A bit less than 1/4th of all pitches from last year were so assessed, and MLB has made the raw contents of that data available at this location. Better yet, there are several bloggers who, unlike me, have the talent and dedication to transform that heaping mess of data into meaningful findings. Most notable, Josh Kalk has been developing player cards, a la what's available at baseball-reference or fan graphs or baseball cube, except with graphs incorporating this incredible new source of information on pitch selection and pitch behavior. He also has developed a remarkable application where you can select any player and any pitch with just about any limiting parameter you could want - say, Bob Howry fastballs to right-handed hitters on 0-2 counts with a velocity above 93 MPH that resulted in swinging strikes - and then view the results on a handy X/Y graph.

As if that's not enough, there's the more user friendly if less revolutionary pitch data commercially available at Baseball Info Solutions which is being applied by the talented folks at Fan Graphs. Fan Graphs now offers data on individual players' pitch selections and velocity, all thoroughly sortable. For instance, Tim Wakefield and Chad Bradford feature the two slowest average fastballs in the major at 74.2 and 78.6 MPH, respectively, while no one threw a changeup with greater frequency last year than Matt Wise, at 54%

There's a gold mine of potential information available at our fingertips, with The Baseball Analysts and The Hardball Times leading the way in this sort of analysis. With far less sophistication than what those guys can offer, let's see what it can tell us about the Cubs' staff.

The Angels (10-6) visit HoHoKam this afternoon at 3:05 to play the Cubs (6-12). The game will be carried on WGN Radio, WGN-TV, mlb.tv and Gameday Audio, but no one will be tuning in, as the world's attention will be focused instead on the University of Illinois' attempt to secure an NCAA Tournament berth.
