Sikkema, Chandler Champlain and Beck Way were traded from the Yankees to the Royals on Wednesday in exchange for Andrew Benintendi, Joel Sherman of the New York Post reports.
Sikkema missed the 2021 campaign due to a lat injury but has been pitching well at the High-A level this year with a 2.48 ERA, 0.83 WHIP and 54:9 K:BB across 36.1 innings. He'll likely remain at that level with his new organization, though he could also make the move to Double-A.
