The Arizona Fall League has announced the 2011 roster for the Washington Nationals affiliated Scottsdale Scorpions.
Outfielder Bryce Harper, pitcher Sammy Solis and catcher Derek Norris head the roster for the defending champions.
It will be Harper's second season with the Scorpions, but his first as a full-time starter. Last year, he was on the taxi squad and was eligible to play only on Wednesdays and Saturdays.
George Washington University pitcher Pat Lehman and Rafael Martin from the Double-A Harrisburg Senators have also been invited.
The Nationals have been allotted two more slots on the roster, one pitcher and one infielder who have yet to be named.
Harrisburg trainer Jeff Allred will be on the coaching staff. Arnie Beyeler from the Red Sox organization is the team's manager and Ken Youce from the Giants will be the hitting coach. Brandon Emanuel of the Angels is the pitching coach.
