Happened to me a ton in my life, guys in work jerks, out of work nice guys. Sox handled it perfect, New Manager, he wanted to see what the situation is with Hanley, saw it wasn't a fit, present and future. Gave him a chance to hook up with other team, so he could continue his career, maybe get paid decent too.
One way or another did not get back on the field again this year. Might come back, but wont get big bucks again.
All players go through slumps, I'm betting Cora didn't like what Hanley gave in hustle or attitude.
