Left-hander Felix Doubront made his second start of the spring for the Red Sox, striking out five over three innings. Doubront allowed four hits and two runs while walking one.
"Better arm speed, better tempo to his overall game," said Red Sox manager John Farrell. "Three innings of work tonight. A good step, and certainly a progressive step. I thought today was just a good day of work for him."
In an encouraging development for the Red Sox, closer Joel Hanrahan turned in a dominant inning, striking out two. The righty had struggled in previous Grapefruit League outings.
Setup man Andrew Bailey worked around a couple of hits and pitched a scoreless inning for Boston.
Lew Ford went 3-for-3 for the Orioles and drove in a run.
Jarrod Saltalamacchia had a good night for Boston, going 2-for-3. Third baseman Will Middlebrooks had a hit and a run while drawing a walk.
Up next: John Lackey will make his fourth start of the Grapefruit League in Sunday afternoon's 1:05 ET road game against the Tampa Bay Rays. Daniel Bard, Junichi Tazawi, Koji Uehara and knuckleballer Steven Wright are also scheduled to pitch. Jacoby Ellsbury and Dustin Pedroia will be among the regulars in the starting nine.
