Trade Deadline Need

I think we can all admit we could use another left-handed bat and a starting pitcher or two. Assuming we only go after one of those positions at the trade deadline which would you rather see the Astros go out and get and what player in particular would you want them to try and acquire?

​

With the two Central Divisions being so weak I am not sure they will be looking to offload anyone (I was looking at Burns for a SP from the Brewers) and I am not sure we would go after/pay for who the Mets or Padre's could be willing to part with.
