SAN FRANCISCO -- Steven Duggar hasn't played in a Major League game. He's not even on the 40-man roster.
Yet No. 5 prospect Duggar's performance in Spring Training, which begins next week for the Giants in Scottsdale, Ariz., could heavily influence the competition for roles in the ballclub's outfield, as well as the definition of those roles themselves.
