This may be even better than a grand slam.
Marlins outfielder and MLB home run leader Giancarlo Stanton has stripped it all down for a sexy new music video with aspiring star Lexy Panterra.
Panterra's twerk videos already have millions of views on YouTube... and now the video vixen is working on her budding pop music career.
In the new video for her track, "So Good," Panterra straddles Stanton in barely-there lingerie.
Stanton, on the other hand, kind of just lays there, though it's definitely appropriate Panterra enlisted the Marlins star to be in her video for "So Good" -- because that's just how he's been at baseball, especially this season.
The pair appear to be a couple in the video, but according to TMZ, they are just friends.
