Jason Day's third shot from short range on the par-5 first hole at Chambers Bay -- his 10th hole in the second round of the U.S. Open on Friday -- sailed through the green and rolled roughly 30 yards off.
The mics caught Day's reaction, which was, "That was a joke."
His fourth shot, however? That was no joke.

That's one way to make a birdie. Day followed that birdie with another birdie on the par-4 11th and was in a tie for eighth at the time of this post.
