The Houston Astros weren't supposed to take Carlos Correa with the No. 1 overall pick in the 2012 MLB First-Year Player draft. They were supposed to take Mark Appel or Byron Buxton. The experts said so.
But no. The Astros defied the experts and selected Correa anyway. It was shocking enough to make the Twitterverse cry out a collective "WOW!"
That's the beauty of the MLB draft. The No. 1 pick is never a surprise in the NFL draft, and it's rarely a surprise in the NBA draft. Both those drafts may indeed be flashier and more watchable, but they're not nearly as unpredictable as the MLB draft.
The Correa pick isn't the only pick that tells the story. There have been numerous shocking No. 1 picks throughout the history of the MLB draft.
Here's a look back at 10 that come immediately to mind.
