Guerrero's best tool is his righthanded power ... Guerrero takes an uppercut stroke and he loses his balance against breaking pitches. It's a pull-oriented, swing-for-the-fences approach that scouts think he will have to change to hit quality pitching.
Since arriving in the Dominican Republic, Guerrero has shown improved speed with above-average times in the 60-yard dash, which is highly unusual for a 26-year-old to start running faster ... [Some] scouts think he can stay in the middle of the infield, although shortstop is probably out of the question
. His hands and actions are playable but he doesn't have the first-step quickness or range to play shortstop and he can be a bit stiff in the field. Second base could be an option for him and a team that likes him a lot will probably play him there.
