Astros sent RHP Ross Seaton outright to Double-A Corpus Christi.

Astros designated RHP Ross Seaton for assignment.

He's now off the 40-man roster. A former third-round pick, Seaton has had an ugly year between Double- and Triple-A this season, posting an 8.18 ERA and 28/26 K/BB ratio over 55 innings. He seems likely to clear waivers.
