Summary: The main piece in a deal that sent Ben Zobrist and Yunel Escobar to the A’s, Robertson is a polished prospect who is close to major league ready. He shows above-average bat speed, an advanced approach at the plate, and the ability to drive the ball all over the field. Robertson is an above-average athlete with average reads and reactions in the field but smooth and soft hands when fielding and transferring to his plus arm. His polish at the plate suggests he will have a solid-average hit tool but his lack of quick steps limits his range and has some questioning whether he’ll be able to stay at shortstop. If he doesn’t, he will have the arm to handle third base and the potential bat to handle second.
