There are a few reasons why this video of an apparent Derek Jeter hole-in-one might be fake:
1) The ball disappears after the tee;
2) The reactions seem a little scripted;
3) Sharlee, Jeter's sister who uploaded the video, captioned it "Love my job!!! Hole in one by #DerekJeter...or is it?"
There is one thing that makes it believable, though.
It's Derek Jeter.
