Rowing, women's eight final
When:
10:04 a.m.
The Americans have won every world championship and Olympics (that's 10 straight) in the women's eight since 2006 and that is likely not going to change. The U.S. bench is so deep that only two members from the London team are back. First-time Olympian Katelyn Snyder is the coxswain.

Tennis, women's gold medal match
When:
4:20 p.m.
The gold medal is up for grabs between Puerto Rican Monica Puig and Germany's Angelique Kerber after heavy favorite and defending champion Serena Williams lost in the third round. Kerber, the first German woman to win a Grand Slam since Steffi Graf, with her victory at the Australian Open in January, is hoping to join her countrywoman as an Olympic gold medalist too. The bronze medal match between Czech Petra Kvitova and American Madison Keys is at 1:40 p.m.
