VIDEO: Pete Alonso Mashes Absurd 474-Foot Blast to Upper Deck and Nearly Nails Fan

You'd probably never expect to be almost hit by a ball when you're sitting in the third deck at a baseball game. Well, that certainly changes when Mets' rookie superstar Pete Alonso at the dish.

Alonso's 31st of the year was an absolute moon shot. Extending the Mets' lead over the Minnesota Twins, Alonso sent the ball 474 feet to the third deck.

The 24-year-old is on pace to shatter the Mets' franchise record for home runs, and is still proving that his victory in the Home Run Derby was no fluke.

When Alonso steps up to the plate, you better keep your head on a swivel.
