Mejia didn't factor into the decision in Monday's 6-5 loss to the Pirates, allowing two runs on six hits and two walks over five innings. He struck out seven.
Making his 2021 debut, Mejia tossed 65 of 99 pitches for strikes in a strong effort and exited the game in line for the win before the Arizona bullpen made a mess of things in the seventh inning. The 24-year-old likely earned a longer audition in the rotation with this performance.
