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.
