Let’s check in on the Astros’ bullpen during these first 11 games of the season. The Astros’ bullpen (like most teams) is a work in progress at this early stage of the season. By that, I mean the team is still figuring out reliever roles to some extent, and new relievers (either returning from the injured list or being cycled between AAA and the ML roster) will affect the future composition of the bullpen.
All of the small sample caveats apply to our review. And this is particularly applicable to ERA or RA/9 which can have a distorted look because relievers have only pitched a few innings.
