D'Backs infielder Tony Abreu, Cubs catcher Max Ramirez, Royals outfielder Gregor Blanco and Mets infielder Luis Hernandez are on waivers, according to Ken Rosenthal of FOX Sports (on Twitter). Adam Rubin of ESPNNewYork adds that Nick Evans and Pat Misch of the Mets are also on waivers.
It's not surprising to see Abreu on waivers, since Arizona made him available earlier in the month. Ramirez is no stranger to waivers, having been claimed twice this past winter. Hernandez doesn't have an obvious role on the Mets and has drawn trade interest.
