The Red Sox face a need to replenish their young starting pitching after using that depth in trades to address weaknesses elsewhere on the roster, according to MassLive.

Craig Breslow, Boston’s president of baseball operations, has dealt several young starters over the past two years as part of that roster-building effort, the outlet reported. Those moves drew on an organizational strength while targeting other needs.

The resulting challenge is to rebuild the supply of young pitching that helped make those trades possible. MassLive’s account describes a shift in Boston’s roster-building priorities: an area that provided trade resources now requires replenishment of its own.

The deals reflect two connected parts of Breslow’s work — addressing weaknesses across the roster and maintaining the pitching depth available to the organization. Young starters have served as a means of pursuing the first objective, leaving the second as an ongoing task.

MassLive identified replenishing that group as a need for Breslow, rather than reporting a specific acquisition or an announced plan. The available source summary does not identify the pitchers traded, detail the returns or specify how Boston intends to add replacements.
