Dressel, 20, first to win three events in one night at worlds

Caeleb Dressel became the first swimmer to win three gold medals on a single night at the world championships in Budapest, Hungary.

The 20-year-old Floridian started with a victory in the 50-meter freestyle, came back about a half-hour later to nearly break Michael Phelps’ world record in the 100 butterfly and closed by leading off a world-record performance in the mixed 400 free relay.

Dressel has six gold medals in the championships, putting him in position to tie Phelps’ record of seven golds at the 2007 worlds. He will close the meet Sunday on the 400 medley relay team.
