9:00 a.m. — Field Hockey: U.S. vs. Australia
After finishing in last place in the 2012 Olympics, Team USA has rebounded in international play. The Yanks won gold at the Pan-American Games last year, a testament to their improvement. An opening match against the Aussies will indicate if the U.S. can contend for the country's third field hockey medal.
3:00 p.m. — Gymnastics: Men’s Team Final
Eight countries will compete to be the Olympic champions. China has won gold in the team all-around for two straight Games. The U.S. is a longshot to win, but success stories like John Orozco, who tore his Achilles last summer but is back to compete, make this a must-watch event.
4:30 p.m. — Women’s Rugby
Rugby Sevens, a form of the sport with seven players on each side, is making its Olympic debut in Rio. The women's medal matches will be interesting. The field includes perennial power New Zealand, which will be the team to beat. The U.S. team features several crossover athletes. Alev Kelter, for example, played flag football, ice hockey, and soccer before joining the U.S. squad.
