The United States is still leading the pack at the 2016 Summer Olympics in Rio de Janeiro.
As Day 4 of the international competition begins, the American athletes have claimed the most medals, 19. China is in second place with 13 medals. Japan and Russia each have 10 medals total, but four of Australia's seven medals thus far are gold, earning the Aussies third place in the medal standings as of Tuesday morning.
Australia's medal standings are in part due to the first ever women's rugby sevens event in Olympic history. The team beat out its neighbor, New Zealand, in a 24-17 win to take home the inaugural gold medal Monday. Canada won in the bronze medal match against Britain.
If you're looking to see who takes home more hardware, here are a few events not to miss on Tuesday. You can watch on NBC-TV or online through live streaming. All events are in Eastern time.
Gymnastics: The women's team all-around is set to compete for medals starting at 3:00 p.m. The US women's team is the team to beat going into this event. Two members of the team, Aly Raisman and Gabby Douglas, were members of the team that won gold in 2012 and were then dubbed the Fierce Five. Joining the two veterans are Simone Biles, Laurie Hernandez, and Madison Kocian. Russian gymnast Aliya Mustafina told the Associated Press through a translator, "It's going to be really difficult to compete against the American team…. They are unbeatable at the moment."
Swimming: The pools will be busy again in Rio Tuesday. Four final events are scheduled for the evening: the women's 200-meter freestyle, the men's 200-meter butterfly, the women's 200-meter individual medley, and the men's 4x200 meter freestyle relay (see the below schedule for times). Michael Phelps, who has taken home the most medals in Olympics history, will face off with Tamás Kenderesi of Hungary in the men's-200 meter butterfly final at 9:28 p.m. Kenderesi won both his heat and semifinal in the event. Katie Ledecky, who reset the world record that she had set in the women's 400-meter freestyle Monday by almost two seconds, will be in for a tough fight for gold against fellow multiple world record holder Sweden's Sarah Sjöström in the women's 200-meter freestyle at 9:19 p.m.
