So tonight's the night the Nationals will officially make Bryce Harper the No. 1 overall selection in the 2010 MLB Draft. That's the part we know. (Shameless plug: Follow all Harper pre-draft stuff in this stream).

Still, this is the place where we will keep track of everything as it happens. We'll also be providing coverage of the Nationals' 7:05 p.m. press conference after the first pick, as Patrick Reddington will be live at Nationals Park. 

For more background on the Nationals' draft plan as a whole, check out Adam Kilgore's piece in the Washington Post and this article by Nationals Farm Authority.
