The Astros signed Velazquez to a major-league contract Monday, Matt Kawahara of the Houston Chronicle reports.
Velazquez cleared waivers Sunday after being designated for assignment by the Astros on Thursday. He was originally outrighted to Triple-A Sugar Land, but Velazquez will rejoin the Astros' 26-man roster to provide the team with depth in the outfield. In a corresponding move, Raynel Delgado was optioned to Sugar Land.
