McCarthy was recalled from Triple-A Columbus on Friday, Mandy Bell of MLB.com reports.
EDGE Analysis
The Guardians lost a pair of starters (Zach Plesac and Aaron Civale) to the injured list, so McCarthy will probably take the bullpen place of Cody Morris, who is elevated to the rotation. He could potentially come in to piggyback either Morris (starting Friday) or Xzavion Curry (likely starting Saturday). McCarthy has a 6.04 ERA and 1.57 WHIP in 22.1 innings across six MLB appearances.
