Cameron Young gets two shot penalty for putting from wrong spot
World number 15 Young, who was fighting to make the cut after a disappointing opening round four-over 74, made the task tougher with a costly mental error on the 16th hole.
Young had putted up close to the hole and marked his ball.
As his ball-marker was on the line of play of both playing partners Englishman Tommy Fleetwood (32) and Japan's Hideki Matsuyama (31), he moved his marker one clubhead-length to the side.
After the other players completed the hole, Young failed to move the marker back to its original position and tapped in from a wrong place incurring a two shot penalty.
Young finished with a 75 to leave him on nine-over well over the projected cut line of four-over.
