Manaea (3-2) was tagged with the loss Thursday against the Red Sox after giving up seven runs on 10 hits and a walk while fanning two across two innings.
Manaea had recorded six straight starts of at least five innings, but pitched his shortest outing of the campaign Thursday while recording season-worst marks in hits and runs allowed, and his two strikeouts represent a season-low figure as well. The left-hander will attempt to bounce back in his next start, scheduled for next week at home against the Astros.
