If spring training is any indication how the season will go, the Astros will most likely be sellers come trade deadline time.
The Astros have given up 108 runs in 17 games, 20 more runs than the next closest team in the Grapefruit League. They are sitting currently in last place with a record of 5-12.
Even though they have struggled, they do have some players who could be attractive to teams and could help them make a push for the playoffs in 2011. Now, I don't expect all these players to be traded, but I think the Astros would be willing to move them if the price is right.
