The Nationals are expected to be sellers this summer, but they don't have a timeline for making any moves. "There's no definitive timeline for doing anything," acting general manager Mike Rizzo said. "Like I've always said, we're always open to make good baseball deals at any time during the season. The corresponding move would be to bring up one of our minor leaguers to take that spot if the trade doesn't fulfill our major league need." Washington could make Adam Dunn, Nick Johnson, Austin Kearns and Cristian Guzman available.
