Tyler Clary grabbed the win with a 4:19.59 to win the A final, though Conor Dwyer nearly ran him down with a wild final 50. Dwyer finished in 4:20.25, while 16-year-old Sean Grieshop took third (4:23.16). The top three swimmers lopped off over five seconds each from their morning swims, but none of them cracked the top 25 in the world.
