CSNwashington.com’s Holden Kushner says first baseman Adam Dunn and troubled outfielder Nyjer Morgan will not be members of the 2011 Washington Nationals.

Kushner says, “After Morgan’s numerous on-field meltdowns and poor performance at the plate, Mike Rizzo can’t justify putting him on next year’s roster. Morgan shouldn’t be allowed on the field again this season. He’s become a danger to himself and his team.”

It’s understandable why the 30-year-old Morgan would not be back. Kushner cites Morgan’s poor on-base percentage (currently .316) for a lead off hitter.

The front office won’t give Dunn a three-year deal even through they should, Kushner adds. Yesterday, Thomas Boswell of The Washington Post agreed, saying, “Dunn is done in Washington.” He added that Dunn’s poor defense far outweighs the positives from his offensive stats.

Dunn and the Nationals have had on and off negotiations throughout the year. It appears more and more likely that the team and Dunn will part ways after his two-year, $20 million deal expires after this season.
