The Red Sox and reliever Junichi Tazawa avoided salary arbitration by agreeing to a one-year, $3.375 million contract. After the 2016 season, Tazawa will become a free agent. Given his uncharacteristically poor 2015, Boston was reticent to pledge any more "free agent" years to the right-hander—who will turn 30 this coming June. Given the efforts by Dave Dombrowski to significantly upgrade the Red Sox bullpen, manager John Farrell will not have to rely as heavily on Tazawa as in the past. Tazawa's burdensome workload was clearly affecting his performance as 2015 wore on.
