The Reds have signed outfielder Terrence Long to a minor league contract. He's been in the majors all of the last five seasons, most recently with the Royals last year. I have no doubt that his .319 career OBP will incite more unrest, but I'd say this is a pretty low-risk move.
They also released Steve Smitherman, which I think was pretty obviously coming.
I'm going to reserve judgement on Long, mostly because I don't really get it (both why he'd want to come here, and why we'd want him).
