The Astros reinstated Weiss (personal) from the paternity list Sunday.
The right-hander was away from the team for the last three days while welcoming a new addition to his family. The Astros haven't clarified what Weiss's role will look like, but he could be available out of the bullpen to cover multiple innings behind Cody Bolton, who will open Sunday's contest. If Weiss isn't used Sunday, he'll be a candidate to start or work in bulk relief during Monday's series opener versus the Dodgers.
