Luke Gregerson did a fine job in the closer role for the Astros this past season, posting a 3.10 ERA and 59/10 K/BB ratio over 61 innings while going 31-for-37 in save opportunities. He’s still under contract for two more seasons, but the Astros are apparently making it priority No. 1 to upgrade the back-end of their bullpen:
Astros relievers ranked sixth in the majors this season with a 3.27 ERA. However, they weren’t nearly as effective down the stretch and while it’s unfair to single out a specific game as a motivation for anything, they melted down in Game 4 of the ALDS against the Royals. One of the Royals’ big strengths has been the high-velocity back-end of their bullpen, so while the price tag in talent would be significant, a major addition like Aroldis Chapman or Andrew Miller has obvious appeal.
