Add Kansas City Royals designated hitter Billy Butler to the list of trade candidates this offseason as Butler's name has surfaced in trade rumors at this year's winter meetings in Nashville. The Baltimore Orioles and Seattle Mariners are said to be two teams showing strong interest in acquiring Butler, according to Bob Dutton of The Kansas City Star.

#Orioles and #Mariners show strong interest in #Royals DH Billy Butler. Could see Seattle as a fit; hard to see a match with Baltimore.

As aforementioned, it is easy to see a potential trade between the Seattle Mariners and Kansas City Royals. The Mariners have a surplus of young pitching to deal from at the major league level and in their farm system, but are desperately seeking an offensive punch.

Butler, 26, had a career season at the plate in 2012, batting .313/.373/.510 with 29 home runs in 679 plate appearances, helping him land his first All-Star bid. He is also under contract through 2014 with a $12.5 million team option for 2015.
