Delvin Perez was drafted by the St. Louis Cardinals with the 23rd overall pick in the first round of the 2016 amateur draft, the final player selected in the first round proper as a number of teams had given up their first round pick due to free agent signings that year. He began his professional career that year with the GCL Cardinals, where he hit .294/.352/.393 in 43 games as the team's shortstop. In 2017, still only 18, he split his time between the Gulf Coast League team and the Johnson City Cardinals. Things did not go as well in his sophomore season, as he hit just .203/.314/.271.
Given his mediocre performance in 2017, the Cardinals did not move him up to full-season ball in 2018, instead sending him to the State College Spikes of the New York-Penn League. The results were again disappointing as in 64 games, he hit .213/.301/.272.
