Top MLB prospect Delvin Perez was taken with the No. 23 pick by the St. Louis Cardinals on Thursday, just days after he failed a drug test.
Perez, a shortstop out of Puerto Rico, was seen as potential top-five pick in the weeks leading up to the draft, with MLB.com projecting him to go to the Milwaukee Brewers with the fifth pick in a recent mock draft.
It is not yet clear what substance cause Perez to fail the test. According to Jon Heyman of Today’s Knuckleball, character issues have been the knock against Perez.
At 6’3”, 165-pounds, Perez has been compared to fellow Puerto Rican shortstop Carlos Correa.
The MLB has declined to comment on the positive test because of the league’s agreement with the Players Association to not publicize drug testing results for prospects.
The 17-year-old played his amateur baseball at Puerto Rico’s International Baseball Academy.
