Both players have quickly returned to the Royals two weeks after the club non-tendered them. The two debuted in the majors last season, but the 25-year-old Arteaga garnered more experience. Arteaga totaled 135 plate appearances, but he batted a nonthreatening .197/.258/.230 without a home run during that span and managed minus-0.7 fWAR along the way. The light-hitting Arteaga didn’t pack much of a punch over 302 PA in Triple-A ball, either, as he slashed .299/.333/.394 with five HRs and 11 stolen bases.
Mejia, whom the Royals acquired from the Dodgers in a 2018 three-way trade, went to the plate 27 times at the big league level in 2019 and hit .227/.333/.273. Like Arteaga, the 25-year-old Mejia also produced at a below-average rate in Triple-A ball, where he put up a .271/.339/.382 line and logged seven long balls with 19 steals over 556 PA.
