Sean Sullivan allowed three runs with three strikeouts over five innings in a loss against the Red Sox on Tuesday.

Sullivan surrendered a run in the first inning on a walk and a triple. He then gave up another in the second on two more walks and a hit. Wilyer Abreu then took him deep for a solo homer in the fifth. Sullivan’s day would be done after five frames at 94 pitches. He struck out three. The 23-year-old left-hander could have his spot in the rotation taken by Tanner Gordon (hip), who is set to make one more rehab start for Triple-A Albuquerque on Wednesday. One more start for Sullivan would come Monday against the Marlins in Colorado.
