Baseball clearly runs THICK in the Harper blood …

Here’s Bryce Harper’s 1-year-old son hitting a MOON SHOT home run off his toy tee ball set Wednesday … and, yeah, safe to say Dad loves it!!!

The Philadelphia Phillies superstar’s kid was getting in some hacks with his plastic baseball bat this week … when suddenly, the little man fired off a rocket DEEP to left-center!!

Check out the swing … little Krew Harper already has the one-handed follow-through down pat!

Bryce was impressed with his boy’s ability … writing of the clip, “That’ll work.”

The effort is pretty amazing … Krew was only born in August 2019 — so, only about 17 years to go until the MLB debut?!

By the way, baseball stars’ infant sons crushing homers is becoming quite the thing in the MLB … have you seen Freddie Freeman’s kid with the bat??
