GM Jim Bowden said Wednesday that Endy Chavez and Nick Johnson must put up good numbers at the plate this preseason, or the Nationals will seek upgrades at their positions through trades.
''You have to score runs,’' Bowden said. ''We have a situation right now that we’re hoping that we can get production in center field and first base.’' Speculation has already begun that Bowden is scouting his former club, the Reds, and their surplus of outfielders, perhaps thinking of going after Ken Griffey Jr. or Wily Mo Pena to play center field.
