Bryson DeChambeau makes his par putt at 18. He signs for a 69 that promised to be so much better. He was blemish free until powering a short par putt through the line on 16. Then the watery tee shot at 17. How quickly things can go south. See also: Matt Fitzpatrick, who sends his tee shot at the generous par-four 14th onto the high bank to the right of the green. Worried about the water on the other side, he fluffs his first chip, then blades his second through the green. The fringe stops the ball dropping into the drink, but the chip coming back stops six feet short, and suddenly he’s staring a double-bogey six in the face.
