The Astros have signed reliever Armando Benitez to a minor league contract.
Benitez, 36, was pitching for the Newark Bears in the independent Atlantic League.
He was 1-0 with 16 saves and a 2.86 ERA in 34 appearances.
"We'll give Armando a chance to finish the season at Round Rock and then determine where we go from there," Astros general manager Ed Wade said in a statement Saturday.
