Nick Johnson, the original Washington Nationals and final Montreal Expos first baseman, has been dealt to the Florida Marlins for Aaron Thompson, a AA pitcher. Here is all I could find about him (firstinning.com)
Joe Beimel was traded for two minor league righties, Ryan Mattheus and Robinson Fabian. Mattheus averaged over a strikeout an inning before having Tommy John surgery in July. Fabian has an ERA over 6 but strikes out twice as many as he walks in Class A.
The Nats also sent cash along both times.
This upshot of all of this is Cristian Guzman is your last remaining Opening Day 2005 Washington National. That just about sums up the last five seasons, doesn’t it?
