First baseman Matt Olson is currently ranked as the A’s overall-best prospect. The 21-year-old slugger is known for his power and ability to take walks, and he’s not too far away from making a major impact on the Oakland Athletics.
Olson led the High-A California League in walks last season, taking 117 free passes. The next highest total was 88, which is an astonishing margin to lead by. His 37 home runs also led the league, six more than the Angels’ Dennis Raben had. He scored a league-high 111 runs, and ranked third in RBIs, with 97.
