Houston optioned Salazar to Triple-A Sugar Land on Friday, Matt Kawahara of the Houston Chronicle reports.
With Yainer Diaz and Victor Caratini at full health, Salazar is expendable. He'll lose his spot on the active roster in order for Zach Cole to have his contract selected. Salazar is 3-for-13 (.231) with a 2:2 BB:K in 11 big-league games this season.
