I saw a headline about interest in A.J. Ellis as well. Rivera seems like the right target, no question on if he'd be available, cost would be minimal, solid defender and framer, not a complete black hole with the bat. Ellis is all of those things but the framing too. As far as bullpen tagalongs go, I could most easily see Ramos + Ellis given they've been linked to Ramos. I'm not sure LHP needs to be a priority if they're giving up on Montgomery as a SP.
