Marinomics: A Dismal Baseball Science

In re: Michael Lewis' NY Times Magazine piece that mentions Beltre's jump...

Players who have enjoyed jumps in various power categories since 1980.

These lists were updated (mostly so Phil Bradley would get on one more, but also because of some stability patterns I saw), to all be the Top 25, Career AB >= 200, Season AB >= 200 (instead of Season AB >= 175). Added Isolated Power and Extra Bases. Added AB numbers to all of the lists to help temper some of them.

UxSLG = Unexpected Slugging Percentage = SLG in Year X - Career SLG
UxTB = Unexpected Total Bases = TB in Year X - Career SLG * AB in Year X
UxIsoP = Unexpected Isolated Power = IsoP in Year X - Career IsoP
UxExB = Unexpected Extra Bases = TB minus Hits in Year X - Career IsoP * AB in Year X
