Boston, MA – With Joel Hanrahan and Andrew Bailey on the disabled list, the Boston Red Sox named Junichi Tazawa as the team's closer.
Hanrahan was put on the 15-day disabled list prior to Tuesday's game against the Minnesota Twins with a right forearm strain.
It's Hanrahan's second trip to the DL in almost a month, having been out of action from April 14-29 due to a strained right hamstring. He allowed two runs in 2 2/3 innings in three appearances since returning to action on April 30.
Bailey has been on the DL with a right biceps strain.
Tazawa is 2-1 with a 2.51 ERA in 14 1/3 innings pitched this season.
