Magnificent Seven win team gold at the
1996 Summer Olympics. She won the all-around and the vault at the 2010
Level 10 National Championships. Jay finished third in the all-around and won the vault at the 2011 American Classic, qualifying to the
2011 U.S. Championships as a result. There, she finished third on the vault and placed 11th in the all-around. As a result, she was invited to the selection camp for the 2011 World Championships and the 2011 Pan American Games. At the
2012 U.S. Championships, Jay won the silver medal on the vault, behind
Alicia Sacramone, and placed 17th in the all-around after falling three times. She was not selected to compete at the 2012 U.S. Olympic Trials. She enrolled at the
University of Georgia in the fall of 2012 to begin competing for the
Georgia Gymdogs in the 2013 season. During her freshman, sophomore, and junior years, she was named an
All-American on the vault. She remained at Georgia for another year as the team's graduate student coach. ==Competitive history==
