The Red Sox put two more runners on base in the sixth, but Zach Britton retired Carl Crawford on a fly ball to center field on his 94th pitch of the night.
Britton appears to be done. Jim Johnson is throwing with a purpose in the bullpen.
Britton has four quality starts in five outings. He's held the Red Sox to one run and five hits, with two walks and two strikeouts.
On the season, Britton has allowed 10 runs and 25 hits 31 2/3 innings. He's walked 12 and struck out 19.
Johnson is entering the game.
