Vladimir Guerrero Jr. took a trip to Top Golf on Monday ... and the results were shockingly average.

The Toronto Blue Jays superstar stepped up to the range mat with what appeared to be a 3-wood in his hands ... and proceeded to show off less power than your average dad.

Watch the clip ... the same violent swing that allows the 20-year-old to launch baseballs 500 feet only yielded some 175-yarders.

OKAY, he ain't exactly Zion Williamson with a golf club ... but come on, look at this kid with a baseball bat in his hands!!!

For their part, Vladdy's friends appeared to be making fun of his lack of pop on the links too!!

Don't worry, baby Guerrero's still raking on the baseball diamond ... he later posted some clips Monday night showing off his classic power.

But, still ... call up Nelson Cruz and get some golf lessons, bro!!!
