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.
2. J.P. Crawford, Phillies
Several teams regret passing on Carl Crawford's cousin in the 2013 Draft, when he somehow lasted 16 picks despite projecting as an all-around shortstop who undoubtedly would stick at the position.
