Kansas City optioned Fermin to Triple-A Omaha on Wednesday.
With Kansas City expected to go with Salvador Perez and MJ Melendez as its lone options at catcher to begin the season, Fermin will miss out on a spot on the Opening Day roster. Fermin performed well in the Cactus League with a .906 OPS in 25 plate appearances before the demotion, and if either Melendez or Perez is to miss time at any point, Fermin will likely be the first catcher called on as a replacement.
