Georgia Tech’s Ollie Schniederjans sounded the warning Wednesday after his rout in the first round of U.S. Amateur match play. They weren’t all going to be as easy as that 6-and-5 laugher.

He didn’t want to be this right. In Thursday’s round of 32 match it took Schniederjans 20 holes to rid himself of Louisiana high school senior Sam Burns. The world’s top-ranked amateur, Schniederjans was 3 up with four holes to play and still backed himself into the corner of elimination. He lost two of those closing holes to a Burns bogey, after taking double bogey himself. Burns outright won another hole with a birdie on the par-3 17th.

Then into sudden death, Burns had a chance for the upset with a 10-foot birdie on the first hole, but left his putt low. A poor drive on the 20th hole led to a Burns bogey, allowing Schniederjans to take the match with a par.

Survive and advance was good enough for the moment. In the afternoon, he was matched against Korea’s Gunn Yang, who on Wednesday eliminated Schniederjans’ Tech teammate Seth Reeves.
