The Houston Astros have certainly done a solid job in upgrading their team heading into the 2015 season. The additions of Luke Gregerson, Pat Neshek and Jed Lowrie will certainly upgrade both the bullpen and either short or third for the Astros going forward. If the younger players on the team take that next step forward, then the 2015 could truly be an exciting time in Houston.
However, that does not mean that all of the Astros problems have been addressed. In fact, far from it. They could still use another arm in the bullpen, either a third baseman or a shortstop, depending on where Lowrie plays, help in left field, and potentially, another starting pitcher. This would appear to be quite the shopping list.
Yet, the Astros still have assets they could move in trade if need be. Jason Castro would be an attractive option for a team in need of help at catcher, and may be a piece the Astros could move to improve one of their own weaknesses. While most of the quality free agents have been picked through at this point, there are still several free agents available that could help.
While Max Scherzer or James Shields would certainly improve the Astros, the idea is for this look through to be realistic. With that in mind, here are five possible targets, in no particular order, that the Astros could focus on to improve the 2015 roster.
