On Road 2028 Olympic Games, the 18-and-Under Rising Stars to Watch
One year into the latest Olympic Quad, we’ve gotten a look at the athletes who could emerge as legitimate medal threats for the 2028 Olympic Games in Los Angeles. The tandem of Japan’s Shin Ohashi and Great Britain’s Filip Nowacki have excelled in multiple breaststroke events, putting up times that rank among the best in the world. A rivalry on the international stage would be great for the sport, much in the way Kosuke Kitajima vs. Brendan Hansen offered intriguing duels.
Beyond Ohashi and Nowacki, there are plenty of rising stars to monitor over the next few years. Japan boasts an impressive crop of burgeoning standouts, including Tatsuya Murasa in the 200 freestyle and Yumeki Kojima and Raito Numata in the individual medley events. Meanwhile, China’s Zhang Zhanshuo has been shown great potential, including at this week’s Chinese National Games.
As the 2025 campaign winds down, here’s a look at the 18-and-under athletes who ranked among the top-20 performers in the world during the past 11 months.
