His home run was 561', the next up was only 483' by Jim Thome. Not associating Riggans with power, I open up his player card and WHAM: POW ranking = 100. Really? This guy? His CON is 35, his Eye is 5. How'd he get 100 POW? Well... I look at the 'Real Life Stats' tab. Could this be some unknown power machine that's slipped my baseball knowledge? Check out his HR total for 2009:

I don't know if it's Puresim's error in importing or if it's the database it's pulling from that's wrong, but SOMETHING is definitely wrong. I think I would have heard of this kid if he hit that many longballs.
Just sharing.

EDIT: Note also how his G, R, H, HR and RBI totals are all 87. That's too much of a coincidence.
