The Boston Red Sox spent an off-day trying to recover from a transatlantic flight and two losses to the New York Yankees.

The bullpen again became a concern as the Yankees scored 22 runs in 12 2/3 innings of work by Red Sox relievers over the weekend.

And now the team has decided to make a move to shore up that bullpen.

Multiple sources have told NESN’s Tom Caron that Nathan Eovaldi will serve as the closer for the Red Sox when he returns from the injured list. They also told Caron that he will serve as a traditional closer, and not as part of a bullpen-by-committee.
