5. The bullpen
Theo Epstein said Wednesday that the bullpen was a top priority for the team this offseason. "We've had a lot of talks with teams about trades in which we'd get a closer back," said Epstein. "We've dabbled in free agency but obviously haven't gotten anything done yet. And the search continues. Our bullpen is not yet a finished product. It will look a lot different on Opening Day than it looks right now."
