HR Debry odds between 5d and Rw

[Regul8er]

The difference is way too noticeable:

5d
Jose Bautista +290
Robinson Cano +500
Prince Fielder +500
Mark Trumbo +500
Matt Kemp +500
Carlos Beltran +650
Carlos Gonzalez +700
Andrew McCutchen +850


Rw
Jose Bautista +175
Robinson Cano +250
Prince Fielder +300
Mark Trumbo +350
Matt Kemp +450
Carlos Beltran +400
Carlos Gonzalez +500
Andrew McCutchen +500

I know it's only a prop bet, but the descrepancy here is unbelievable.
Anyone betting with Rw for the HR Derby is getting royally screwed over.
