Byron Buxton dislocated a finger while diving for a ball in the Arizona Fall League.

It's the latest setback for the Minnesota Twins outfield prospect, who was the top pick in the 2011 draft.

Buxton, 20, was considered to be the top prospect in baseball at the start of the year. He was limited to 31 minor league games this season because of a bruised left wrist during spring training, which he also injured while diving for a ball.
