After David Peterson made his Grapefruit League debut in the beginning of spring training, manager Mickey Callaway stated that there was “definitely a chance” that the former first-round pick could have a role with the major league team at some point this season. At first glance, that may seem like an optimistic outlook for a minor league pitcher who has not pitched above High-A ball and who did not even perform particularly well at that level, as evidenced by his 4.33 ERA in 11 starts. While it wouldn’t be the most egregious instance of a prospect being rushed to the major leagues, one would think that 2020 may be a more realistic ETA for him.
