Dressel was out in 22.83 seconds -- 0.53 seconds under Phelps' pace -- and came home in 26.67 to lead eight men into Saturday's final.

He was a whopping 1.44 seconds ahead of Andrei Minakov of Russia, the second-quickest qualifier.

It's the second world record of Phelps' to fall at this year's worlds. Kristof Milak of Hungary won the 200 fly in 1:50.73, bettering Phelps' mark of 1:51.51 also set in Rome.

Dressel, a two-time Olympic gold medalist, was a swimming star at Clay High School and the University of Florida.
