Considering the uncertain rotation, can the bullpen support them?
Brad Ziegler stepped into the closer role in 2015 and did a great job. Previously, he was more of roaming put-out-the-fire guy, but he seems pretty firmly established in the closer role. The rest of the pen includes Daniel Hudson, Josh Collmenter, Matt Reynolds, Enrique Burgos, and Randall Delgado, with the possibility of bringing up Silvino Bracho at some point. The stats are steady, but this is a very young crew, for the most part, and with only three top guys in the rotation, they are likely to see a lot of work.
Some think it might be better to move Ziegler back into the roaming role he filled before, and give Hudson a shot at closing, but the job is Ziegler’s to lose. If the young arms in this bullpen can come through, they could be (particularly in the first half of the season) the difference between over- or under-.500 baseball.
