Giancarlo Stanton Strips for Erotic Sex Scene In Lexy Panterra Video

Giancarlo Stanton just hit another one out the park ...

TMZ Sports has a first look at the MLB home run leader like we KNOW you've never seen him before ... as a VIDEO VIXEN ... getting up close and personal -- and damn near naked with Lexy Panterra.

Lexy's twerk vids have gotten millions of views on YouTube (you've seen them) but she's also a budding pop star, and enlisted the slugger for some sexy visuals for her track, "Deep End."

Stanton doesn't do much in the video -- he kinda just lies there (typical), but let's face it, when you're as yoked (and rich) as the Miami Marlins superstar, that's pretty much all you have to do.

BTW -- the chemistry in the video is evident, but we asked, and they're just friends. Although, we honestly can't see why. Now stop reading and enjoy.
