The MLB trade deadline is quickly approaching and the Astros are going to miss out on the best relief pitchers on the market if they don't make a move soon. Orioles closer Zach Britton and Reds closer Raisel Iglesias are the two big-names the Astros have been rumored to be interested in, but is Astros GM Jeff Luhnow willing to give up enough to make a deal happen? Adding an impact player after the non-waiver trade deadline like the Astros did last year with Justin Verlander, is not very likely.
