Ronny Mauricio

This comes after the Mets added catcher Francisco Alvarez and right-hander Matthew Allan over the weekend. Andres Gimenez is up in the majors, so the addition of Mauricio means that the organization's top-three prospects will all be at the alternate training site. Mauricio is just 19 years and not close to the majors, but it certainly doesn't hurt to put him in this environment.
