RIO DE JANEIRO, Aug. 13 (UPI) -- The United States won its 1,000th gold medal Saturday night -- the first nation to do so -- when Simone Manuel solidly won the women's 4x100 swimming relay, and the U.S. men's 4x100 meter swimming relay team set a new Olympic record to help Michael Phelps grab another gold medal before retiring.
After becoming the greatest Olympian in history two nights ago, Phelps claimed one more gold in what is expected to be his final Olympic race -- which he and his teammates made sure was not much of a contest.
Ryan Murphy gave the U.S. an early half-second lead in the 4x100 meter relay, setting a world record as Cody Miller jumped in. Miller kept the U.S. in contention despite their lead narrowing before Phelps took his turn in the pool. Phelps got a small lead, which Nathan Adrian turned into a huge lead -- and helping the team set a new Olympic record for the race.
The only challenge to the Americans came from Great Britain, who lost by more than a full second to take the silver. Australia won the bronze medal just behind Great Britain.
Women's 4x100 relay
Kathleen Baker led the Americans with the backstroke, with Lilly King keeping the race close while swimming the breaststroke. But the team did not take the lead until Dana Vollmer swam the fly. Manuel dominated the last stretch of the race after inheriting a solid lead from Vollmer, helping the team finish two seconds ahead of the rest of the field.
Australia and Denmark, who took the silver and bronze medals, were separated by one one-hundredth of a second in the race's finish.
Women's 100 meter dash
Thompson was never challenged in the race, winning by one-tenth of a second as her lead widened before she crossed the finish lane. Fraser-Pryce, who has won gold in the race at the last two Summer Olympics, was seeking to become the first woman in track to win three gold medals in a row.
Fraser-Pryce wound up taking bronze after American runner Tori Bowie lunged at the finish line to narrowly snatch the silver medal.
Women's beach volleyball
The quarterfinals are set for women's beach volleyball after Russia beat Spain 2 to 0 and Brazil beat China 2 to 0 in the day's late matches.
Sunday's quarterfinals matches include two Brazilian teams, one facing Switzerland and the other facing Russia, while Germany faces Canada in the second match of the day and the United States will play Australia in the day's last match.
Great Britain's Jessica Ennis-Hill won the silver medal in the event, after handily winning the 800 meter and finishing in the top three in the 100 meter hurdles, high jump and 200 meter race. Although she'd entered the day with a 72-point lead in the heptathlon, Ennis-Hill ended up losing the overall event by 35 points because of weak performances in the throwing events.
Brianne Theisen-Eaton of Canada took third in the heptathlon, finishing more than 100 points behind Ennis-Hill.
