Freeing up space is necessary from time to time unfortunately. I'm facing the same decision with Altherr, who I really don't want to give up on but may have to. I guess I just feel like Heyward, now that he's hitting for little power and middling average, and not stealing bases, doesn't really help in fantasy anymore. Even if Alford is very risky as a prospect now, it seems like someone would have given you something better for him. Maybe not, dunno.
