Romero (finger) was added to the Athletics' 60-man roster pool Wednesday.
The 26-year-old dealt with a finger injury during spring training before being reassigned to minor-league camp in early March, but he'll have another chance to stake his claim to a roster spot. Romero spent 2019 at Triple-A and had a 3.96 ERA, 1.40 WHIP and 81:36 K:BB across 72.2 frames.
