1. Corey Seager, Dodgers
His brother Kyle is an All-Star, and Corey should be even better. He led the Minors in hitting (.349) and doubles (50) in 2014, then batted .337/.425/.561 during a September callup last year -- at age 21. Seager may eventually move to third base, but his combination of a sweet left-handed stroke, bat speed, strength, uncanny feel for hitting and mature approach give him a higher offensive ceiling than any Major League shortstop except for Carlos Correa.
