This is the first time Hader has been on the IL for an injury in his nine major-league seasons. The Astros signed Hader to a five-year, $95 million contract prior to last season. He had a 2.05 ERA and was 28-for-29 in save chances this year, also garnering his sixth All-Star selection, before landing on the IL.

Josh Hader going on the injured list was part of a series of moves the Astros made Tuesday involving their bullpen.
