Houston Astros closer Josh Hader was transferred to the 60-day injured list on Friday as he continues dealing with a biceps injury that has kept the left-handed pitcher out of action.
The roster move allowed Houston to create space on their 40-man roster to bring up right-handed pitcher Peter Lambert, whose contract was purchased from the minors. Meanwhile, the team sent reliever Christian Roa down to their Triple-A affiliate in Sugar Land.
The 32-year-old Hader earned All-Star honors last season after posting a 6-2 record with a 2.05 earned run average and recording 28 saves across 48 relief outings. Throughout his nine-year major league career with Milwaukee (2017-22), San Diego (2022-23), and Houston, the six-time All-Star has compiled a 34-31 record with a 2.64 ERA and 227 career saves.
Lambert, who celebrates his 29th birthday on Saturday, was scheduled to make his first appearance in an Astros uniform as a starter against St. Louis on Friday. Since entering the majors in 2019, all with Colorado, Lambert has appeared in 74 games (including 35 starts) and holds an 8-19 record with a 6.28 ERA.
The 27-year-old Roa had struggled in his seven relief appearances for Houston this season, posting a 5.19 ERA before being demoted.
