BoSox name Tazawa closer

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.
