There’s really no need to sell how great Corey Seager is to anyone, as any baseball fan knows he may be one of the best young SS in the game today. Still a young 21 years old and ranked the 5th best prospect in baseball by BA pre-2015, he has the potential to be a middle-of-the-order bat who can take his team to the next level.
Defensively, Seager is just as outstanding at either SS or 3B. Much like Manny Machado in Baltimore, he has such great hands, a great arm, and range that he makes the transition between the positions seamlessly.
