OK, Broxton is signed, the Reds presumably will try Chapman as a starter. They have Redmond as a backup starter.
Some member of the rotation likely will go.
The obvious candidate is Mike Leake. He had the worst year last year and his stuff may point to a rocky career. But he is young, was very good in 2011, and maybe the return in a trade won't be so great right now.
The second candidate is Homer Bailey. He seemed to turn the corner late last season. Pitched a no-no, a great playoff performance. But has Homer shown over a full season that he is a TOR guy or solid number three? Should the Reds sell high? Could bring a good return.
The third candidate is Bronson Arroyo. Bronson redeemed himself well last year. But his contract has only one year left, as I recall, so he may be attractive to a contender looking for a solid veteran without a long commitment. It's the Reds' chance to save some money on salary for next year and get a decent return. Bronson might have approval or other rights that could complicate this.
Cueto and Latos seem pretty set, not including them.
I expect something soon. Just guessing, but it could be that the Broxton signing was done with the Chapman move and a trade of one starter all lined up.
