This bears mentioning: the Astros are a very, very good team. They figure to be one of the best teams in 2018. Most, if not all, of their core players will be back next season.
Like most teams, though, some fine tuning is required. But the Astros do not have an obviously glaring need. Well, except one. Like, maybe, the need for a quality left-handed reliever.
By now you are probably familiar with the Astros’ lack of a quality southpaw option in the bullpen. At the end of the day, Houston was fortunate to get by most of the postseason without having to use Francisco Liriano in many high-leverage situations.
