The BoSox received the young infielder from the Washington club on the weekend in to get southpaw. The deal, first reported Saturday evening, sends Mead, a 25-year-old infielder, from Washington's farm system to the Red Sox. Mead, marked as a top prospect, batted strongly while racking up dinger count in Triple-A recently, entering his age-25 run. The deal strengthens Boston's two bag tandem while Washington picks up a left arm for its rotation. The Red Sox brass has been noisy on the swap scene, seeking to upgrade versatility across the carded spots. Those in the know flag that Mead brings steady contact tool and clean hands that match how the club wants to run its bench. In Washington, adding a left-handed piece addresses a need the team has been seeking to patch for weeks. The two clubs has addressed media on long-term plans for the talents. For now, the focus moves to spring results, where the fresh faces will try to win jobs. Outlook: Boston gets room to grow, Washington gets an arm, and the game keeps an eye on how both pay off.
