• Making sense of Gordon's suitors
Gordon, 31, spent the first nine seasons of his career in Kansas City and was selected to the American League All-Star team in each of the past three seasons.
The Royals reportedly offered the outfielder a four-year deal worth $12 million-$13 million per year, according to ESPN. But Gordon is seeking a contract worth closer to $20 million per year, and has plenty of suitors.
Of course, things change all the time during free agency and if the Royals change their offer to meet Gordon's wishes, a return may still be possible.
Royals GM Moore: Reckless to comment on negotiations
The Cardinals, Orioles, Giants and Angels -- although owner Arte Moreno has said the club is unlikely to land a marquee free-agent outfielder -- have all shown interest in Gordon.
With Gordon unlikely to return, the Royals are looking at other options for the outfield including Denard Span, Austin Jackson, Gerardo Parra and Alex Rios, who was with the Royals in 2015.
