They said it...
" He has a classic lefthanded swing, though he doesn't always pull the ball. Rizzo prefers to work the center of the field and go pole-to-pole. He has power in his bat, though he doesn't always try to muscle the ball. His barrel stays in the zone a long time, though that means his swing tends to get long at times. He's a plus defender, and I even had some people tell me that he could play above-average first base in the bigs right now. Rizzo has good glovework and footwork around the bag."
