The day began with manager Davey Johnson calling a team meeting in which he appealed for more aggression at the plate and mistook his starting pitcher's heat pad for a neck brace. It ended with the Washington Nationals accomplishing something they hadn't done all season -- coming from three runs down to win a ballgame. The Nationals swept a day-night doubleheader from the Minnesota Twins on Sunday, climbing back to .500 and showing signs of an offensive breakthrough by pounding out a combined 24 hits in the 7-0 opener and 5-4 nightcap.
