Johnson came over from the Rays this offseason as part of the James Shields-Wil Myers blockbuster.
The 29-year-old Johnson batted .179/.218/.241 in 173 plate appearances for the Royals this season — a steep decline from last season’s .242/.304/.350 in 331 plate appearances. While Johnson offered little with the bat this season, he did provide some value on defense and on the basepaths. Both UZR/150 (+15.9) and The Fielding Bible (nine runs above average) loved his work at second base at second base this season, and he went 14-for-14 in stolen base attempts.
