Donald Trump Hits Kid In The Head W/ Baseball At World Series

Welp, he was trying to do something nice ... but former President Donald Trump knocked a kid upside the head with a baseball at the World Series, and the video is pretty funny.

(The boy is okay!!)

#45 was in the house at Truist Park in Atlanta for game 4 of the World Series last Saturday night -- sitting in an open-air suite with Melania Trump -- a game the Braves won 3-2 over the Astros.

The video shows a young boy desperately attempting to get DT's attention. Finally, the ex-prez heard the kid, and asked him to throw a baseball for him to sign.

The boy complies ... and Trump -- who claimed he could've gone pro as a baseball player -- made a nice catch, snagging the ball, which was underthrown by the kid.

The 75-year-old politician grabbed a marker from a Secret Service agent ... and signed the baseball.

Then came time to toss the ball back ... and that's when Trump plunked a kid square in the dome, after an adult male who was with the kid failed to make the routine catch.

Thankfully, the boy appears to be okay ... and fans nearby were able to retrieve the baseball.

The silver lining ... we previously reported on Trump-signed balls that have sold for around a thousand bucks a pop.

As for Trump, he spoke about his baseball prowess back in 2004.

“I was supposed to be a pro baseball player. At the New York Military Academy, I was captain of the baseball team. I worked hard like everyone else, but I had good talent.”
