That's a perfectly fine question.
Morrow is a recent example, however the two disparities are coming closer together, and Morrow only has 768 IP under his belt. Only 30 points apart now.
Strasberg is a more extreme example, since he K's so many and doesn't walk a lot, but still a lack of IP: 710.
I think the best example here is Javier Vazquez: career 4.22 ERA and 3.75 xFIP and a plenty large sample. Still, that's a far cry from Hutchison's ERA-xFIP disparity.
EDIT: Curt Schilling and Randy Johnson could qualify as well, but again, you're dealing with extreme cases.
