Byeong-Hun An is proving again that he's going to be a tough out in this championship. On No. 5, he drained a 33-foot eagle putt to go 2 up. He followed it immediately with a bevy of fist pumps. It seemed An was ready to take control of the match when he nailed an 8-foot birdie on the next hole to go 3 up.
If ever David Chung needed to stop the wave of momentum, it was now. He did so on No. 7, sticking his approach to 6 feet and making the putt to gain a hole back.
In the other semifinal match, Patrick Cantaly trailed Peter Uihlein 2 up as they went to No. 10. Cantaly was in the fairway with 122 yards to the flagstick discussing what shot to hit with his caddie. Cantaly said he was going to go with a low liner. He instead struck a high-arcing shot that bounded until it stopped 5 feet left of the hole. His caddie turned and said, "His definition of a low shot is different in his mind, I guess," drawing laughs.
He made the putt to cut the deficit, but then gave it back on the next hole.
