As of this minute, Bryce Harper is still in Las Vegas. Next week, Harper will be in D.C. for an introductory press conference. After that, though? According to GM Mike Rizzo, Harper will go to the Gulf Coast League, and if he holds his own, the Nationals will give him a chance to prove himself in the Arizona Fall League.

Rizzo reportedly said "we'll see if [Harper's] ready" for the Arizona Fall League. That will be Nationals' fans first benchmark to see how Harper is progressing.
