Since the day the Mariners acquired Encarnacion, there have been rumors about him being shipped elsewhere. It was a mild surprise when he was with the team in spring training, but Encarnacion has been a valuable member of the lineup during his time year. While his average is low (down to .225), Encarnacion has made up for it with power (12 home runs) and his ability to get on base (.358 on-base percentage).
The fact that he’s played a passable first base this year might open up National League teams as an option for him, but right now the best fits appear to be in the American League and even in the Mariners own division.
