Chen, the only undefeated male skater in the 2017-18 season, will be joined on the team by 2016 U.S. winner Adam Rippon and teenager Vincent Zhou, the 2017 world junior champion, as U.S. officials overlooked Ross Miner, the surprise runner-up at Saturday's national championships in San Jose, California.
The Feb. 9-25 Winter Games in Pyeongchang, South Korea, will be the first Olympics for all three selected. Miner was named the second alternate behind 2014 Olympian Jason Brown as the selection committee took numerous criteria into consideration in making its choices.

Rippon, 28, had finished fourth at the championships and Zhou third.
"I feel like I have better criteria than second- and third-place here," Rippon told reporters after falling on his opening quadruple lutz jump.
Chen is the only man to receive credit for landing five different types of quadruple jumps in international competition.
“This is exactly what I wanted my entire life, and I’m ready for it,” Chen said when asked about going to the Games.
The 18-year-old, who was born in Salt Lake City, began skating on a practice rink designed for the 2002 Olympics, NBCSN reported.
When he won a novice national title in 2010, he said on the broadcast that he would be a factor in the 2018 Olympics.
U.S. Figure Skating earlier selected national champion Bradie Tennell, 2010 Olympian Mirai Nagasu and teenager Karen Chen for the 2018 Games. The remainder of the U.S. team will be named later on Sunday.
