UCLA gymnast Katelyn Ohashi earned a perfect "10" score for her floor routine at Under Armour's 2019 Collegiate Challenge on Saturday (January 12th), and the video of her performance has gone viral after it was tweeted out by UCLA Gymnastics. Before going to UCLA, Ohashi, who's a senior, had competed at the elite level, but she decided to go to college and compete on the collegiate level after injuring her back and shoulder.
