This probably doesn’t mean much for the Yankees who would still have to trade for Greinke even to have a shot at signing him. It is worth noting that Close is also the agent for Derek Jeter.
Like I said though, it probably doesn’t mean much. The Yankees don’t appear interested in Greinke fearing that he might not be able to cut it in the Bronx and don’t want to give up the top prospects to find out.
The Yankees have contact the Royals at least once though and will probably continue to monitor trade talks just to make sure they don’t miss out on getting him cheaply.
