Michael Phelps and the United States swimming team have fully established their dominance at the 2016 Rio Games. Phelps has already secured gold medals No. 19, 20, 21, and 22 of this career, while Lilly King and Katie Ledecky have lived up to every expectation and led the women’s side with four more golds. Altogether, Team USA has built a substantial medal lead over rival China thanks to the swim squad gathering 22 of the nation’s 38 medals won so far.

But more could be on the way as the swimming events wind down in Rio Friday and Saturday night.

Phelps, in his fourth and final Games, enters the last Olympic race of his career and can further increase his stranglehold on the record books in the men’s 100-meter butterfly Friday. Phelps will face teammate Tom Shields, as well as China’s Zhuhao Li, France’s Mehdy Metella, and Russia’s Aleksandr Sadovnikov, among others, in the final. Meanwhile, Nathan Adrian and Anthony Ervin will represent the U.S. in the men’s 50-meter freestyle final.

For the women, Ledecky can notch her fourth gold of the games in the 800-meter freestyle but faces some stiff competition from teammate Leah Smith, Australia’s Jazz Carlin, and Hungary’s Boglarka Kapas. Already considered the favorite after her uplifting performances in Rio, the 19-year-old Ledecky broke her own Olympic record with a run of 8:12.86 seconds in the preliminary heats on Thursday, besting Kapas’ second-best qualifying time by nearly seven seconds.

Following the conclusion of the preliminary heats on Friday afternoon and evening, Saturday night’s events include the medal races for the women’s 50-meter freestyle and 4x100-meter medley relay, while the men vie for the 1,500-meter freestyle and their 4x100-meter medley relay.
