USA (Claes/Sponcil) def. BRA (Ana Patricia/Rebecca)
The U.S. now has two women's beach volleyball teams with perfect 3-0 streaks at the 2020 Tokyo Olympics, as newcomers Kelly Claes and Sarah Sponcil downed the Brazilian pair of Ana Patrícia Silva Ramos and Rebecca Cavalcanti Barbossa Silva in three sets: 17-21, 21-19, 15-11.
Could a potential U.S. medal matchup between Claes/Sponcil and veterans April Ross and Alix Klineman be in the cards?
INTERNATIONAL MEN'S MATCHES
ROC (Krasilnikov/Stoyanovskiy) def. CZE (Perusic/Schweiner)
Czechia's Ondrej Perusic and David Schweiner had medal hopes but those fell hard at the hands of Russian Olympic Committee representatives Viacheslav Krasilnikov and Oleg Stoyanovskiy.
Down 1-0 after a 21-19 first set, Krasilnikov and Stoyanovskiy went to work and emerged with 21-13 and 15-8 wins to seal a place in the next round.
MEX (Gaxiola/Rubio) def. LAT (Plavins/Tocs)
A straight-sets win for Mexico's Josue Gaxiola and Jose Rubio kept the duo's hopes alive for a medal, although the ROC's win means they'll head to the Lucky Losers bracket.
CHI (Grimalt M./Grimalt E.) def. SUI (Heidrich/Gerson)
Chile cousins Marco and Esteban Grimalt came through with a 21-17, 21-18 win over Switzerland's Adrian Heidrich and Mirco Gerson.
Marco Grimalt made a series of crucial blocks midway through the second to set up victory and secure a spot in the round of 16.
ESP (Herrera/Gavira) def. POL (Kantor/Bartosz)
Spain's Pablo Herrera and Adrian Gavira edged Poland's Piotr Kantor and Bartosz Losiak 31-29, 19-21, 15-7 in a tense encounter to seal the first lucky losers spot. But, Spain’s Herrera said he had no plans to celebrate.
"A party? I'm 39 years (old), I think I'm going to eat something and go to bed," he said.
INTERNATIONAL WOMEN'S MATCHES
Latvian duo Tina Graudina and Anastasija Kravcenoka dominated Kenya's Gaudencia Makokha and Brackcides Khadambi, 21-6, 21-14 -- sending the latter team packing. While Latvia's 2-1 record qualifies them for the round of 16, the Kenyans did not win a single match during the Pool D preliminary rounds.
The Spanish pairing of Liliana Fernandez and Elsa Baquerizo have advanced to the round of 16 -- but their fourth match opponents, Japan's Murakami Magumi and Ishii Miki, are headed to the lucky loser bracket. Fernandez and Baquerizo looked sharp in their straight-set victory over Japan, 21-15, 21-10.
Cuba's Leila Martinez and Lidiannis Echevarria have advanced to the round of 16 after beating Dutch duo Katja Stam and Raisa Schoon, 21-17, 21-17.
