It’s Friday afternoon and the Washington Nationals’ series of community relations events, dubbed the Winter Caravan, is entering the homestretch. Newly-minted manager Manny Acta, centerfielder Nook Logan and pitcher Mike O’Connor sit inside the bustling Red Cross Blood Donor Center in Fairfax, Va., signing baseballs for kids both young and old. One kid, of the 45-year-old variety, tries to make small talk with O’Connor as he collects his signed ball.
