The Reds have been busy on the waiver wire, but quiet elsewhere. Beyond picking which young players upon which to make dice rolls, GM Dick Williams has largely held his hand thus far. That’s not terribly surprising, for a variety of reasons.

The club’s most obvious potential trade chips come with no-trade protection (Joey Votto, Brandon Phillips) or play positions that aren’t in huge demand (Phillips, Zack Cozart). There was never a strong prerogative to deal from among the Reds’ other controllable assets, such as righty Anthony DeSclafani and center fielder Billy Hamilton. At the same time, after spending about two years compiling prospects, the organization has plenty of young players who are ready to compete for major league opportunities in 2017, so there aren’t a lot of needs.

Still, it would be surprising if the team makes it through the winter without striking at least one major-league contract. Cincinnati nearly did so a winter ago, giving MLB deals only to Blake Wood and (in mid-March) Alfredo Simon. While the Yankees actually did manage to avoid handing out a 40-man spot to a free agent in 2015-16, it’s a rarity.

And it isn’t as if the Reds are fully loaded for 2017, particularly if they hope to have an outside chance at turning into a contender. In particular, the bullpen appears ripe for an addition. That’s especially true of the open closer role; while Raisel Iglesias, Michael Lorenzen, or even Tony Cingrani would represent internal options, giving any of those youngsters the opportunity would also mean boosting their expected arbitration earnings. Cincinnati might as well make the investment to add another arm, while utilizing them in set-up roles. Alternatively, or additionally, the Reds could look to add some veteran arms — either swingman types or pure relievers — to provide depth.

So, what are the options should Cincinnati decide to open up one of its prized 40-man roster spots? Let’s run down a few of the remaining bullpen arms that could make sense…
