On night one of the MLB Draft, all eyes were on the Pirates' first pick Seth Hernandez. He could very well be the greatest high school arm to get drafted of all time, given the way development has changed across the modern era. Two rounds later, the Pirates selected Murf Gray, a third baseman from Fresno State University. MLB Pipeline and Baseball America were not very high on him, yet FanGraphs had him ranked as a top-20 draft prospect and Pittsburgh somehow stole him at pick 73.
Essentially, using FanGraphs' rankings as justification, the Pirates secured three potential first-rounders with their three picks at Nos.
