However, this doesn’t mean either player should be packing their bags anytime soon. The fact that they cleared waivers means that teams were not interested.
Sometimes you get lucky and an injury can lead a team to reevaluate and try to trade for these players as we saw last year when the Mets traded John Buck and Marlon Byrd to the Pirates for Vic Black and top prospect Dilson Herrera. However, both were also owed very little and had expiring contracts unlike Niese and Granderson.
Most teams will put a dozen or so of their players on revocable waivers to try and gauge whether there’s any interest in the players. If a player is claimed by another team, teams have 48 hours to work out a deal or the player can be pulled back.
There were rumors and speculation that Bartolo Colon would be placed on waivers after the non-waiver deadline, but according to reports that never happened and quite frankly I never expected it to as the Mets could likely get more in the offseason or include him as part of a bigger deal for a bat.
