The BoSox received infielder from the Washington Nationals on Saturday in return for southpaw. The move, reported that night, sends Mead, a prospect in his mid-20s player, from the Washington farm system to the club. Mead, noted as a pre emerging talent, slashed strongly while racking up dinger count in Triple-A this past year, entering his age-25 season. The move strengthens Boston's keystone area while Washington adds a left arm for its hurlers. The Red Sox brass has been active on the swap scene, looking to upgrade versatility across the infield. People close to the talks note that Mead brings strong bat and steady glove that match how the club wants to handle its bench. On the other side, adding a left-handed piece addresses a need the team has been trying to close for a stretch. Neither side has spoken on record on future fit for the swap pieces. For immediately, the focus moves to how the numbers read, where the fresh faces will try to earn spots. Outlook: Boston gets room to grow, Washington gets an arm, and the baseball sphere watches how both work out.
