Barnes is expected to continue being used as Boston's primary setup reliever, Jason Mastrodonato of the Boston Herald reports.
Although Barnes is in a position to see plenty of high-leverage situations in the near future, his status as the team's go-to setup man may be in jeopardy once Tyler Thornburg (shoulder) comes off the DL. After pitching in three games (3.2 innings) this season, Barnes has struck out five batters, allowed just two hits and picked up a win.
