Salazar will be included on the Astros' Opening Day roster, Brian McTaggart of MLB.com reports.
With Houston optioning Korey Lee to Triple-A Sugar Land on Tuesday, Yainer Diaz and Salazar will share backup duties behind starting catcher Martin Maldonado. Salazar has flashed decent power in recent minor-league seasons and produced a sparkling .979 OPS over 27 plate appearances this spring in the Grapefruit League.
