They've got a workhorse in Hernandez, a 100-BB/30-HR OF/1B in Wilkerson and one of the best 2B's in the game in Vidro to build upon. Their farm system is pretty depleted though, especially with Clint Everts going down with Tommy John Surgery. They do have Harris to play 3B, Izturis to play SS, Johnson to play 1B and Beltran and Cordero at the end of a ballgame to close it out (Cordero is more ready now, Beltran has way more upside). If they get their rotation healthy and some of their youngsters produce, they could reach .500 again next season. This move to Washington was exactly what this team needed.
On a semi-related note, I'm so glad they're not moving the team to Northern Virginia. First off, Virginia doesn't deserve the name over D.C. Second, I am really sick of this NoVa stupidity, that's just dumb. Glad to see MLB making a good decision here, but it should have come a long time ago. Screw Peter Angelos and his Baltimore *******s.
