The shrinking bullpen of the Houston Astros may need an injection of help from outside. Joe Smith is out for 6-8 months following surgery, Collin McHugh is moving up to the starting rotation and Tony Sipp may be exiting via free agency. Zach Britton is a reliever on the free agent market that could be that booster shot.
Some might say there is plenty of young talent that could step up and fill the void. Josh James, Cionel Perez and Framber Valdez are promising young pitchers often mentioned.
