Mookie Betts somehow managed to drive a golf cart into a pond

Not everyone can be good at everything. That's just not fair. You can't, for instance, be great at baseball, bowling, Rubik's Cubes and driving golf carts. The universe just wouldn't allow that much talent in one person.

Nope -- it was simply the combination of gravity and a parking brake not fully applied. Here's Betts' explanation:

Just remember -- if you ever go golfing with Betts, pack your water wings.
