Yeah, the golf club part of the story is even more weird than the rest. Who runs out of the house with a golf club when they hear an accident? Also, she apparently had to break open the rear window of the car to get him out?? That's hard to believe.
He hits a fire hydrant and tree, in an Escalade, going less than 33mph while apparently backing out of the driveway and, what, the doors were so horribly mangled that they didn't work? Are we supposed to believe she then hoisted him from the broken window? Everything about this story is a little odd. I smell cover-up... they were probably fighting, he left, either in a rage or trying to escape her and the golf club, and the rest is history.
Not a big deal in the grand scheme of things, but Tiger has a squeaky clean image and he certainly wouldn't want any domestic drama going public.
