A 36-year-old who threw 14 innings in the majors last season had the most interesting offseason in baseball.
Craig Breslow, the former Red Sox left-handed reliever and a free agent, still has a lot of work to do. But he’s about two-thirds of the way through a project meant to rehabilitate not his arm, but his entire arsenal — and by extension, his career.
On Monday, Breslow unveiled a new arm slot to scouts from about a dozen teams at an indoor facility in Waltham. The Red Sox were there, as were the Mets, Cubs, Blue Jays, Twins and Reds, among others.
