But with three lost holes in a row at the end of regulation, Xiong felt the title match, which he had dominated all day, slip away. After getting as big as a 4-up advantage at the turn, Redman won No. 10 to get back to 3-down and tried his best to rally with birdies on Nos 13 and 14. When Xiong matched those, he was three up with four to play, then Redman birdied No. 15 to get back to having an outside chance. And Xiong gave him some help, losing Nos. 16 and 17 to par. That's three straight losses, and a huge swing in momentum.

The match was all square with one hole to play.

“After 16, I started to feel it,” Xiong told the WGA. “I got a little more nervous, a little more tense. Before that, I was loose. Doc and I had fun out there … before 16, it was a relaxing round. We tried to keep it light, even though it’s such a big stage.”

Redman had a 20 foot putt to win the match on No. 18, and he nearly holed it, lipping out.

Redman conceded Xiong’s four-foot putt for par on 18 because he said he didn’t want to win on a possible Xiong miss. Prior to that, Xiong gave Redman par putts on Nos. 16-17 that measured longer than two feet.

In extra holes, (starting at No. 1) Xiong had a 15-foot birdie putt to win, and like Redman on No. 18, he lipped out. The duo halved the second with pars and the third with birdies. Redman two-putted for his birdie on No. 3, while Xiong needed to make a 15-footer to keep his title hopes alive.

On the par-4 fourth, Xiong hit his approach to 12 feet, and Redman was more than 100 feet away, a very difficult two putt under the pressure of the 22nd hole. Xiong easily two-putted for par, and when Redman missed his par putt, Xiong, the 2016 Junior PGA winner, had clinched the biggest title of his young career.

Redman, who we will be keeping a close eye on at the U.S. Amateur as he eyes a potential spot on the U.S. Walker Cup team, said that despite digging himself so big of a hole he never gave up.

“I wanted to stick to what I’d been doing, see if I could get some birdies,” he said. “There was nothing crazy going on in my head.”

SEMIFINAL RECAP

Norman Xiong def. Derek Bard, 2&1

This was a tight one between Bard, the start golfer from Upstate New York, who played for Virginia and won the Monroe Invitational and Palmetto Intercollegiate in the spring. He displayed the kind of play that gives him a current Golfweek/AmateurGolf.com World Ranking of 26 with three-straight birdies on Nos. 5-7 (the last one matched by Xiong) to go 2-up.
