Jesse Dougherty of the Washington Post believes that Javy Guerra could replace Hunter Strickland on the 26-man roster.
The Nationals released Strickland on Saturday, and it not only clears up a spot on the 26-man roster, it also makes room on the 40-man. That is necessary to add Guerra, who was re-signed in December to a minor league contract. Dougherty also mentions that the Nationals could go with a third catcher like Welington Castillo, or utility-man Emilio Bonifacio.
