Astros sent RHP Ryan Weiss outright to Triple-A Sugar Land.

Weiss was removed from Houston’s 40-man roster last week and passed through waivers unclaimed. The 29-year-old swingman struggled mightily in his stateside return, forging a disastrous 7.62 ERA and 30/20 K/BB ratio across 26 innings over nine appearances before being shipped to the minors back in early May.
