Another lefty option, my pick is Tielbar, and someone to be the closer as FA signings.
The rest of the bullpen, I feel, can be filled decently from within and see who works out. There are so many internal options, but nobody to close out games. Funderburk showed something at the end of the season, but im not ready to trust him as the only LH option.
Obviously some signings with Spring Training invites need to happen, as well. Depending on availability, might be able to find a decent arm in the Rule 5 draft, too. So many options.
