Restocking the bullpen is on the to-do list for all Major League teams during the offseason, and the Houston Astros are no different. If the 2025 season proved one thing, it's that if Josh Hader goes down with an injury, the Astros' bullpen looks completely different. Hader and Bryan Abreu are an elite tandem to close out games, but the Astros need to find a high-leverage reliever who can get outs in the middle innings.
Their search could lead to one of 2025's most surprising success stories. Brad Keller opened his Major League career as the mainstay of the Kansas City Royals' pitching staff, but he may have been forgotten about after dreadful stops with the Boston Red Sox and Chicago White Sox in 2024.
