Caeleb Dressel broke two short-course world records, plus lowered another American record, in one afternoon in Budapest on Saturday.
Dressel, competing in the International Swimming League final, crushed the 100m butterfly world record, lowered his own 50m freestyle world record and got under his own 100m freestyle American record leading off a relay.
The ISL is contested in a short-course, 25-meter pool. The biggest meets, such as the Olympics, world championships and national championships, are held in 50-meter pools.
Still, what he did on Saturday was mighty impressive.
Dressel, who broke Michael Phelps‘ 100m butterfly world record at the 2019 World Championships, shattered the short-course record in the 100m fly by three tenths of a second, clocking 47.
