2020 Tokyo Olympics swimming: Katie Ledecky gets 800m three-peat; Dressel sets 100m world record

The Americans won more medals in the swimming pool on Friday night

The United States has seen swimmers Katie Ledecky and Caeleb Dressel have large amounts of success at the 2020 Tokyo Olympics thus far. On Friday, the two Americans took center stage once again.

Ledecky got off to an excellent start, winning gold for the third straight time in the 800-meter freestyle. Not only is that mark historic, but it is also the first time at the Tokyo Games that Ledecky finished ahead of Australia's Ariarne Titmus in an individual race. Ledecky took gold with a time of 8:12.57, while Titmus finished in 8:13.83 for the silver. Italy's Simona Quadarella finished in third.

The American jumped out to an early lead in the first 100 meters of the race. Titmus was about a half length behind Ledecky through the first 400 meters, but she eventually faded a few lengths behind. Ledecky led for the entire race.

Before that race, Dressel won the 100-meter butterfly final and broke the world record in the process, finishing in 49.45. He won the event in 49.45 seconds, surpassing the old mark -- which Dressel himself set in 2019 -- of 49.50.

As he almost always does, the American got off to a great start off the blocks. His main competition was Kristof Milak of Hungary. But Milak could not catch Dressel.

Milak did take silver and was followed by Switzerland's Noe Ponti in third place.

Dressel also competed in the 4x100-meter mixed medley relay, and the United States ended up finishing fifth.

Below are recaps of the other races that took place on Friday.

4x100-meter mixed medley relay final

Great Britain won the gold medal with a world record time of 3:37.58 and the United States finished in fifth place.
