During March I did an in-depth study of Jack Cust’s surprising 2007 season. Recently I’ve been wondering why he was struggling so mightily in 2008. I did an update to the study and published the results at The Hardball Times.

Edit:  I posted to THT Live about Cust’s performance over the last couple days.  I don’t intend to imply that I can divine the end to a player’s slump or the beginning of a hot streak.  It’s more of a case of me musing out loud about and trying to learn how the PITCHf/x tools fit into the scouting/performance picture.
