The Astros spent a large part of the past season attempting to beef up their pitching staff, and it didn’t really pay off. Their most anticipated addition, Tatsuya Imai, really struggled, and a small handful of pitchers were left to carry the rotation. Injuries also hit their rotation early on, and they lost their ace for a good part of the first half of the season. That is not to undermine some of the outstanding performances from Peter Lambert and Hunter Brown. Their staff needs some new arms and some work. The Astros used a club-record 19 starting pitchers. They managed to wear out their best arms and set a record for the most starting pitchers used. That is something that just cannot happen again.
