Lucas Giolito was a bit of a gamble for the Nationals 2012 first round draft pick. He had an elbow issue, which eventually required Tommy John surgery, but he was also a former consensus number one overall pick before the injury. The Nats, with their history of being unafraid to draft proven talent with injury history (see: Purke, Matt; Rendon, Anthony), hope that Giolito's ceiling will pan out. Jason Parks, the infamous national prospect and player development writer for Baseball Prospectus, believes that Giolito has an elite ceiling.
Twice on Monday, Parks tweeted about Giolito's top tier talent and ability to reach "elite potential." This gels with Adam Kilgore's article in The Post last week, which had Nats' Scouting Director Kris Kline unapologetic about picking Giolito over Cardinals' star rookie Michael Wacha. Kline told Kilgore, “If I had to make the same decision again and [General Manager Mike Rizzo] had to make the decision again, we would take Lucas.”
Parks' tweets about Giolito are below. All of this shows why Baseball America has Giolito as the Nats number one pitching prospect in the organization.
