The Miami Marlins felt that they had a good building block to create a deep bullpen to help shorten games leading into the 2017 season. The pen returning from last season was closer A.J. Ramos, Kyle Barraclough, Nick Wittgren, Jose Urena, David Phelps, and Dustin McGowan.
With the numbers that all of these relievers put up last season, it was thought that adding in veteran relief in Junichi Tazawa and Brad Ziegler would result in an elite bullpen.
