The Mets placed Nick Evans, Luis Hernandez and Pat Misch on waivers Monday, according to a baseball official who was not authorized to speak publicly because the process is secretive.

The results of the waiver process should be known Wednesday.

Manny Acosta is the lone Met in a tenous position who is out of options and may not have been placed on waivers Monday, according to the source. Acosta seemingly is the third combatant in the battle with Blaine Boyer and Jason Isringhausen for one relief spot.

The Padres had appeared interested in Hernandez via trade, but just acquired Alberto Gonzalez from Washington instead.

Misch can opt out if he clears waivers, but he is more likely to stay if he is unclaimed, because of his attractive minor league salary and his familiarity with the organization.

Evans would have to report to Triple-A Buffalo if unclaimed. His being placed on waivers means that Lucas Duda would break camp with the Mets if something should go awry with Carlos Beltran in the next day or two.
