Merrifield is coming off an All-Star campaign during which he played all 162 games and hit .302/.348/.463 with 16 home runs, 41 doubles, and a major-league leading 10 triples.
The 30-year-old led the American League in stolen bases in 2017 and 2018 but swiped only 20 bags this past season.
Merrifield is signed under a very team-friendly four-year, $16.25-million extension that kicked in this past campaign. He has a $6.5-million team option for 2023.
Royals general manager Dayton Moore said during the season that "the ask would be just crazy" for any team looking to acquire Merrifield via trade.
