King has won a spot in the Marlins' Opening Day bullpen, Christina De Nicola of MLB.com reports.
After signing a one-year deal with Miami in February, King lines up to be the top left-handed relief option for manager Clayton McCullough. King was sharp this spring, posting a 1.13 ERA and 9:4 K:BB over eight innings, and given his likely role, he could top the career-high 12 holds he recorded between the Rangers and Cardinals in 2023.
