In the 18th round, the Cardinals picked Seton Hall junior righthander Shane McCarthy.
In April 2016, McCarthy became the first Seton Hall pitcher ever to throw a perfect game. McCarthy struck out eight batters against LIU-Brooklyn to earn the perfect game.
The 2017 season was not as kind to McCarthy. He made 12 starts and compiled a 3-7 record and a 5.13 ERA with no complete games.
