I just assume any young Nationals pitcher is an injury riddled mess who needs to be switched to relief appearances as soon as possible lest they be unable to pick up a pen with their dominant hand by the time they turn 30.
I try to be hopeful for Cavalli, but as a 1st round Nats pitching prospect since 2012 his company is Erick Fedde, Dane Dunning, Mason Denaburg, Jackson Rutledge, and Seth Romero. I know Rutledge is still hanging in there, but he's about to turn 24 and has yet to throw a pitch in AA.
