Athletics added INFs Eric Campbell and Robert Puason, RHPs Wandisson Charles and Miguel Romero and OFs Luis Barrera and Brayan Buelvas to their player pool.
Campbell will report to Oakland, taking the roster spot of Jorge Mateo, who was traded to the Padres. The other five players will report to the A’s alternate site. Puason is 17 and has yet to play an inning of pro ball, but he’s considered one of the club’s top prospects.
