The Houston Astros moved left-hander Josh Hader to the 60-day injured list Friday as the closer continues to recover from a biceps injury.
The move gave the Astros 40-man roster space to purchase the contract of right-hander Peter Lambert, while right-hander Christian Roa was optioned to Triple-A Sugar Land.
Hader, 32, as an All-Star last season when he went 6-2 with a 2.05 ERA and 28 saves in 48 relief appearances. The six-time All-Star is 34-31 with a 2.64 ERA and 227 saves in nine seasons with the Milwaukee Brewers (2017-22), San Diego Padres (2022-23) and Astros.
Lambert, who turns 29 on Saturday, was set to make his Houston debut in a start against the St. Louis Cardinals on Friday. In 74 career appearances (35 starts) since 2019, all with the Colorado Rockies, Lambert is 8-19 with a 6.28 ERA.
Roa, 27, had a 5.19 ERA in seven relief appearances with the Astros this season.
