For the second year in a row, the Nationals will have the most highly touted prospect in the Arizona Fall League.
After sending 2009 No. 1 overall pick Stephen Strasburg to the AFL a year ago, the Nationals will send 2010 top pick Bryce Harper to the circuit this year.
Harper will join Scottsdale as a member of the taxi squad, meaning he will be able to play two games per week for the Scorpions, who are managed by Washington's Randy Knorr. Harper turns 18 on Saturday.
Harper, who did not play in the minors this season after signing at the Aug. 17 signing deadline, has been getting acclimated to pro ball with the Nationals at the club's instructional league. After spending most of his time this year with JC of Southern Nevada at catcher, Harper will make the full-time transition to right field.
