Hamilton (lat) tossed a bullpen session Sunday and will make a rehab appearance with Double-A Somerset on Wednesday, per the Associated Press.
Hamilton was expected to pitch for Somerset on Friday, but he was scratched due to back spasms. The reliever is apparently past the issue given his ability to toss a bullpen Sunday. Wednesday's outing could be Hamilton's final minor-league appearance, and he could be back in New York's bullpen shortly thereafter.
