Arano was recalled by Atlanta on Saturday.
Arano showed high-leverage potential in his first two seasons in the majors in 2017 and 2018, posting a 2.57 ERA and 3.13 FIP in 70 innings of work, but he battled elbow issues in 2019 and shoulder troubles in 2020, throwing just 4.2 innings. Still just 26 years old, Arano may still possess his former promise, but the fact that Atlanta kept him in the minors for over a month to start the year suggests expectations should be modest for now.
