Here are our 4 to Watch for Saturday Aug. 6:
1. Women's Beach Volleyball
Two of the United States' stars of the London Olympics take to the beach in Rio. They were opponents four years ago, but this time around Manhattan Beach's Kerri Walsh-Jennings teams with the player she defeated for London gold, Costa Mesa's April Ross, in Rio. Walsh-Jennings, 37, will be aiming for her fourth consecutive gold medal to write another chapter to her incredible career. The retirement of Walsh-Jennings' long-time teammate, Misty May-Treanor, opened the door for her to partner with Ross, who attended the University of Southern California and won a silver medal in London.
2. Men's Water Polo
The United States, led by several Southern Californians, opens water polo competition and its quest for an elusive gold medal against powerful Croatia. The U.S. team is captained by Tony Azevedo, who lives in Long Beach, but will be making a homecoming at the 2016 Rio Olympics. Azevedo, 34, was born in Rio de Janeiro and his father, Ricardo, played on the Brazilian national water polo team. Azevedo is making his fifth appearance at the Olympics, the most by any U.S. water polo player. The team finished sixth in 2002, seventh in 2004, then earned silver at the 2008 Beijing Olympics to tie the best-ever finish by a U.S. team before an eighth-place showing in London.

3. U.S. Women's Soccer
Diamond Bar's Alex Morgan and the United States women's soccer team got things rolling Wednesday in a 2-0 defeat of New Zealand. Morgan, who scored three goals at the 2012 London Olympics, and Carli Lloyd scored the first two goals for the defending gold medalists in Rio. France, which made its Olympics debut in London, is coming off a convincing win over Colombia in its group state opener.
The game is a rematch of a 2012 London Olympics meeting that saw France jump out to a surprising 2-0 lead before the U.S. equalized ahead of halftime. Morgan scored in the second half to help the U.S. win 4-2.
Team USA is back in action against Colombia Tuesday at 3 p.m. PT.
