Here's New York Mets superstar rookie Pete Alonso SLAUGHTERING a baseball so hard ... IT NEARLY LEFT TARGET FIELD!!!
The incredible home run came in the top of the 8th inning Wednesday when Alonso stepped up to bat against Twins reliever Matt Magill.
Pete took the first 3 pitches ... but then when he got a slider that hung over the heart of the plate -- he absolutely destroyed it, parking it into the 10th row of the THIRD DECK!!!
Seriously, watch the ball fly ... it lands only a few feet from the highest seat in the park!
