3:35pm: The Royals officially announced the extension, according to MLB.com's Dick Kaegel. Moore is under contract through 2014.
1:48pm: The Royals are set to sign GM Dayton Moore to a four-year extension, according to Bob Dutton of the Kansas City Star. The deal, which could be officially announced tonight, will keep Moore in charge through 2014. He became GM in 2006, when he agreed to a five-year deal that locked him up through 2010.
When we heard last week that the Royals were considering an extension for their GM, ESPN.com's Keith Law wrote that there was no good reason to do so.
