Red Sox manager John Farrell confirmed that Scott earned a spot on the Opening Day roster, Tim Britton of the Providence Journal reports.
With Tyler Thornburg dealing with a shoulder impingement and set to open the season on the DL, Scott will take his place in the bullpen, giving Farrell three lefty relievers to choose from in any given game. In his first exposure of the big leagues last season, Scott tossed six scoreless innings, conceding six hits and two walks while striking out five batters. He'll be slated for lower-leverage work initially, but could move up the pecking order in the bullpen if his performance warrants it.
