Sánchez, who has four sisters and three brothers, was discovered in 2014 when a Cuban catcher named Lednier Ricardo was auditioning for teams in the Dominican Republic. Ruben Amaro Jr., then the Phillies’ general manager, and Mike Ondo, the team’s director of pro scouting, dispatched special assistant Bart Braun to take a look at Ricardo. The workout was at the Phillies’ academy in Boca Chica. Luis Garcia, one of the Phillies’ scouts in the Dominican Republic, was responsible for providing a couple of pitchers so Ricardo could take batting practice. Sánchez was one of the pitchers that Garcia brought to the workout.
