Harper wouldn't even be in my top 10. He left as a free agent after generally playing hard and well while he was here. Plus he had to watch the WS. I reserve my ire for guys who actually hurt the team. Here's ten in no particular order, mostly weighted toward recent years because for 2005-2011 it was hard to dislike anything but some of the worst offenders.
For specific onfield heartbreak, nothing personal:
Pete Kozma
Daniel Descalso
For being jerks and sucking:
Papelbon (also an jerk as an opponent)
Hunter Strickland (same)
Felipe Lopez
Matt Williams
For apathy and sucking:
Austin Kearns
Lastings Milledge
Rafael Soriano
For being whiny and sucking when it mattered (I feel slightly bad about this one, but the dude pretty much flushed two playoff seasons down the toilet):
Storen
