Astros' Rogelio Armenteros: Throws three scoreless

Armenteros allowed two hits and struck out one over three scoreless innings Monday against the Mets.

Armenteros filled in for Collin McHugh (back) and was impressive against New York's B-teamers. McHugh's injury is not considered serious, so it's likely Armenteros opens at the Triple-A level for a third consecutive season.
