Angulo signed a minor-league contract with the Athletics and received an invitation to spring training.

The 26-year-old split 2019 between Double-A and Triple-A and had a 3.45 ERA, 1.29 WHIP and 88:38 K:BB over 82.2 innings, with most of his struggles coming at the higher level. Angulo will face long odds to make the Opening Day roster.
